82ee620dc6 ARM: OMAP: AM35xx: fix UART4 softreset
During kernel init, the AM3505/AM3517 UART4 cannot complete its softreset:

omap_hwmod: uart4: softreset failed (waited 10000 usec)

This also results in another warning later in the boot process:

omap_hwmod: uart4: enabled state can only be entered from initialized, idle, or disabled state

From empirical observation, the AM35xx UART4 IP block requires either
uart1_fck or uart2_fck to be enabled while UART4 resets.  Otherwise
the reset will never complete.  So this patch adds uart1_fck as an
optional clock for UART4 and adds the appropriate hwmod flag to cause
uart1_fck to be enabled during the reset process.  (The choice of
uart1_fck over uart2_fck was arbitrary.)

Unfortunately this observation raises many questions.  Is it necessary
for uart1_fck or uart2_fck to be controlled with uart4_fck for the
UART4 to work correctly?  What exactly do the AM35xx UART4 clock
tree and the related PRCM idle management FSMs look like?  If anyone
has the ability to answer these questions through empirical functional
testing, or hardware information from the AM35xx designers, it would
be greatly appreciated.

bf76523727 ARM: OMAP AM35xx: clock and hwmod data: fix UART4 data
Add missing terminators to the arrays of IRQ, DMA, and address space
structure records in the AM35xx UART4 hwmod data.  Without these
terminators, the following warnings appear on boot:

omap_uart.3: failed to claim resource 58
omap_device: omap_uart: build failed (-16)
WARNING: at /home/paul/linux/arch/arm/mach-omap2/serial.c:375 omap_serial_init_port+0x198/0x284()
Could not build omap_device for omap_uart: uart4.

Also, AM35xx uart4_fck has an incorrect parent clock pointer.  Fix it
and clean up a whitespace issue.

Fix some incorrectly-named macros related to AM35xx UART4.

89ea25835a ARM: OMAP AM35xx: clock and hwmod data: fix AM35xx HSOTGUSB hwmod
Partially fix the hwmod data for the AM35xx USB OTG hwmod.  This
should resolve the following boot warning on AM35xx platforms:

omap_hwmod: am35x_otg_hs: cannot be enabled for reset (3)

While here, also fix the clkdev records, to avoid warnings about
duplicate clock aliases.

The hwmod is also connected to the wrong interconnect.  It should be
connected to the IPSS, not the L4 CORE.  But that is left for a future
fix, since it probably has a dependency on some hwmod core changes.

The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.

This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.

Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

afd6bb3873 Fix OMAP EHCI suspend/resume failure (i693) '354ab856' causes
an oops on boot for all omap3xxx platforms that use usbhs_omap for
EHCI. The actual oops comes from faulty ehci-omap cleanup, but the
failure caused by the change is evidenced here:

[    3.655059] ehci-omap ehci-omap.0: utmi_p1_gfclk failed error:-2
[    3.661376] ehci-omap: probe of ehci-omap.0 failed with error -2

utmi_p1_gfclk is a clock that exists on OMAP4, but not OMAP3. In the
OMAP3 case, it is configured as a dummy clock. However, OMAP4 lists
the dev_id as NULL, but OMAP3 lists it as "usbhs_omap".

Attempting to get that clock from ehci-omap then fails. The solution
is to just change the clock3xxx_data.c for dummy clocks used in the
errata fix to match the dev_id, NULL, used in clock44xx_data.c.

Tested on BB-xM.

commit 8259573b (ARM: OMAP2+: nand: Make board_onenand_init() visible

removing the static in the header file, it created a duplicate definition
in the .c and the .h files, resuling in a build error:

05011f711f ARM: OMAP3: PM: cpuidle: optimize the clkdm idle latency in C1 state
For a power domain to idle all the clock domains in it must idle.
This patch implements an optimization of the cpuidle code by
denying and later allowing only the first registered clock domain
of a power domain, and so optimizes the latency of the low power code.

The functions _cpuidle_allow_idle and _cpuidle_deny_idle are
not used anymore and so are removed.

One of the main contributors of the low power code latency is
the PER power domain. To optimize the high-performance and
low-latency C1 state, prevent any PER state which is lower
than the CORE state in C1.

commit e7410cf7 (OMAP3: PM: move device-specific special cases from PM

some remnants behind, namely the call to clkcm_allo_idle() for the
clockdomains in the MPU pwrdm.  Remove these since they are not
necessary and cause unwanted latency in the idle path.

e055548953 ARM: OMAP2+: powerdomain: allow pre/post transtion to be per pwrdm
Iteration over all power domains in the idle path is unnecessary since
only power domains that are transitioning need to be accounted for.
Also PRCM register accesses are known to be expensive, so the
additional latency added to the idle path is signficiant.

In order allow the pre/post transitions to be isolated and called
per-pwrdm, change the API so passing in a specific power domain will
trigger the pre/post transtion accounting for only that specific power
domain.  Passing NULL means iterating over all power domains as is
current behavior.

5165882a38 ARM: OMAP3PLUS: hwmod: reconfigure IO Daisychain during hwmod mux
IO Daisychain feature has to be triggered whenever there is a change in
device's mux configuration (See section 3.9.4 in OMAP4 Public TRM vP).

Now devices can idle independent of the powerdomain, there can be a
window where device is idled and corresponding powerdomain can be
ON/INACTIVE state. In such situations, since both module wake up is
enabled at padlevel as well as io daisychain sequence is triggered,
there will be 2 PRCM interrupts (Module async wake up via swakeup and
IO Pad interrupt). But as PRCM Interrupt handler clears the Module
Padlevel WKST bit in the first interrupt, module specific interrupt
handler will not triggered for the second time

Also look at detailed explanation given by Rajendra at

dea6200ba0 ARM: OMAP4: PRM: Add IO Daisychain support
IO daisychain is a mechanism that allows individual IO pads to generate
wakeup events on their own based on a switch of an input signal level.
This allows the hardware module behind the pad to be powered down, but
still have device level capability to detect IO events, and once this
happens the module can be powered back up to resume IO. See section
3.9.4 in OMAP4430 Public TRM for details.

fe7ea0062f ARM: OMAP3: PM: correct enable/disable of daisy io chain
Currently the enabling and disabling of IO Daisy chain is not
according to the TRM. The below steps are followed to enable/
disable the IO chain, based loosely on the "Sec 3.5.7.2.2
I/O Wake-Up Mechanism" section in OMAP3630 Public TRM[1].

Steps to enable IO chain:
[a] Set PM_WKEN_WKUP.EN_IO bit
[b] Set the PM_WKEN_WKUP.EN_IO_CHAIN bit
[c] Poll for PM_WKST_WKUP.ST_IO_CHAIN.
[d] When ST_IO_CHAIN bit set to 1, clear PM_WKEN_WKUP.EN_IO_CHAIN
[e] Clear ST_IO_CHAIN bit.

Steps to disable IO chain:
[a] Clear PM_WKEN_WKUP.EN_IO_CHAIN bit
[b] Clear PM_WKEN_WKUP.EN_IO bit
[c] Clear PM_WKST_WKUP.ST_IO bit by writing 1 to it.

Step [e] & [c] in each case can be skipped, as these are handled
by the PRCM interrupt handler later.

75a4433e40 ARM: OMAP2+: PRM: fix compile for OMAP4-only build

to detect incorrect usage.  However, several unrelated omap3 PRM

the omap2_prm stubs, causing them to disappear on OMAP4-only builds.

This was unnoticed until the IO chain support was added and introduced
a new function in this section which is referenced by omap_hwmod.c:

aef2b89662 ARM: OMAP: Fix Beagleboard DVI reset gpio
Commit e813a55eb9 ("OMAP: board-files:
remove custom PD GPIO handling for DVI output") moved TFP410 chip's
powerdown-gpio handling from the board files to the tfp410 driver. One
gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in
the Beagle board file. This causes the tfp410 driver to fail to request
the gpio on Beagle, causing the driver to fail and thus the DVI output
doesn't work.

This patch removes several boot errors from board-omap3beagle.c:

 - gpio_request: gpio--22 (DVI reset) status -22
 - Unable to get DVI reset GPIO

There is a combination of leftover code and revision confusion.
Additionally, xM support is currently a hack.

For original Beagleboard this removes the double initialization of GPIO
170, properly configures it as an output, and wraps the initialization
in an if block so that xM does not attempt to request it.

For Beagleboard xM it removes reference to GPIO 129 which was part
of rev A1 and A2 designs, but never functioned. It then properly assigns
beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the
hack of initializing it high. Additionally, it uses
gpio_set_value_cansleep since this GPIO is connected through i2c.

Unfortunately, there is no way to tell the difference between xM A2 and
A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL
GPIO used on A3 and beyond is not used on rev A1 and A2, there are no
problems created by this fix.

Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

got rid of a bunch of ifdefs in the MUSB code. Looks like the
platform init code is still using these dropped defines though,
which in many cases results the board defaulting always to host
mode.

Currently the situation is that USB_MUSB_HDRC is the main
Kconfig option with additional USB_GADGET_MUSB_HDRC so only
these two should be used to select between host and OTG mode.

Fix the situation for omaps. The following users should fix the
platform init code in a similar way:

The current Makefile compiles the cpuidle34xx.c and cpuidle44xx.c files
even if the cpuidle option is not set in the kernel.

This patch fixes this by creating a section in the Makefile where these
files are compiled only if the CONFIG_CPU_IDLE option is set.

This modification breaks an implicit dependency between CPU_IDLE and PM as
they belong to the same block in the Makefile. This is fixed in the Kconfig
by selecting explicitely PM is CPU_IDLE is set.

The linux coding style recommend to use no-op functions in the headers
when the subsystem is disabled instead of adding big section in C files.

3f0ea7645a ARM: OMAP AM33xx: powerdomains: add AM335x support
Add offset & mask fields to struct powerdomain

In case of AM33xx family of devices, there is no consistency between
PWRSTCTRL & PWRSTST register offsers in PRM space, for example -

PRM_XXX           PWRSTCTRL     PWRSTST
=======================================
PRM_PER_MOD:      0x0C,         0x08
PRM_WKUP_MOD:     0x04,         0x08
PRM_MPU_MOD:      0x00,         0x04
PRM_DEVICE_MOD:   NA,           NA

And also, there is no consistency between bit-offsets inside
PWRSTCTRL & PWRSTST register, for example -

PRM_XXX           LOGICRET  MEMON  MEMRET
=======================================
GFX_PWRCTRL:      2,        17,    6
PER_PWRCTRL:      3,        25,    29
MPU_PWRCTRL:      2,        18,    22
WKUP_PWRCTRL:     3,        NA,    NA

This means, we need to maintain and pass on all this information
in powerdomain handle; so adding fields for,
   - PWRSTCTRL/ST register offset
   - Logic retention state mask
   - mem_on/ret/pwrst/retst mask

Currently, this fields is only applicable and used for AM33XX devices.

c59b537d87 ARM: OMAP2+: Simplify dmtimer clock aliases
The OMAP dmtimer driver allows you to dynamically configure the functional
clock that drives the timer logic. The dmtimer driver uses the device name and
a "con-id" string to search for the appropriate functional clock.

Currently, we define a clock alias for each functional clock source each timer
supports. Some functional clock sources are common to all of the timers on a
device and so for these clock sources we can use a single alias with a unique
con-id string.

The possible functional clock sources for an OMAP device are a 32kHz clock,
a system (MHz range) clock and (for OMAP2 only) an external clock. By defining
a unique con-id name for each of these (timer_32k_ck, timer_sys_ck and
timer_ext_ck) we can eliminate a lot of the clock aliases for timers. This
reduces code, speeds-up searches and clock initialisation time.

2b2d352300 ARM: OMAP2+: Move dmtimer clock set function to dmtimer driver
OMAP1 uses an architecture specific function for setting the dmtimer clock
source, where as the OMAP2+ devices use the clock framework. Eventually OMAP1
device should also use the clock framework and hence we should not any
architecture specific functions.

For now move the OMAP2+ function for configuring the clock source into the
dmtimer driver. Therefore, we do no longer need to specify an architecture
specific function for setting the clock source for OMAP2+ devices. This will
simplify device tree migration of the dmtimers for OMAP2+ devices.

From now on, only OMAP1 devices should specify an architecture specific
function for setting the clock source via the platform data set_dmtimer_src()
function pointer.

0b30ec1cb7 ARM: OMAP: Remove timer function pointer for context loss counter
For OMAP2+ devices, a function pointer that returns the number of times a timer
power domain has lost context is passed to the dmtimer driver. This function
pointer is only populated for OMAP2+ devices and it is pointing to a platform
function. Given that this is a platform function, we can simplify the code by
removing the function pointer and referencing the function directly. We can use
the OMAP_TIMER_ALWON flag to determine if we need to call this function for
OMAP1 and OMAP2+ devices.

The benefit of this change is the we can remove the function pointer from the
platform data and simplifies the dmtimer migration to device-tree.

The platform data variable loses_context is used to determine if the timer may
lose its logic state during power transitions and so needs to be restored. This
information is also provided in the HWMOD device attributes for OMAP2+ devices
via the OMAP_TIMER_ALWON flag. When this flag is set the timer will not lose
context. So use the HWMOD device attributes to determine this.

For OMAP1 devices, loses_context is never set and so set the OMAP_TIMER_ALWON
flag for OMAP1 timers to ensure that code is equivalent.

67d2e760ae ARM: OMAP2+: Fix external clock support for dmtimers
Currently, the dmtimer determines whether an timer can support an external
clock source (sys_altclk) for driving the timer by the IP version. Only
OMAP24xx devices can support an external clock source, but the IP version
between OMAP24xx and OMAP3xxx is common and so this incorrectly indicates
that OMAP3 devices can use an external clock source.

Rather than use the IP version, just let the clock framework handle this.
If the "alt_ck" does not exist for a timer then the clock framework will fail
to find the clock and hence will return an error. By doing this we can eliminate
the "timer_ip_version" variable passed as part of the platform data and simplify
the code.

We can also remove the timer IP version from the HWMOD data because the dmtimer
driver uses the TIDR register to determine the IP version.

d1c1691be5 ARM: OMAP: Add DMTIMER capability variable to represent timer features
Although the OMAP timers share a common hardware design, there are some
differences between the timer instances in a given device. For example, a timer
maybe in a power domain that can be powered-of, so can lose its logic state and
need restoring where as another may be in power domain that is always be on.
Another example, is a timer may support different clock sources to drive the
timer. This information is passed to the dmtimer via the following platform data
structure.

struct dmtimer_platform_data {
	int (*set_timer_src)(struct platform_device *pdev, int source);
	int timer_ip_version;
	u32 needs_manual_reset:1;
	bool loses_context;
	int (*get_context_loss_count)(struct device *dev);
};

The above structure uses multiple variables to represent the timer features.
HWMOD also stores the timer capabilities using a bit-mask that represents the
features supported. By using the same format for representing the timer
features in the platform data as used by HWMOD, we can ...

1. Use the flags defined in the plat/dmtimer.h to represent the features
   supported.
2. For devices using HWMOD, we can retrieve the features supported from HWMOD.
3. Eventually, simplify the platform data structure to be ...

struct dmtimer_platform_data {
	int (*set_timer_src)(struct platform_device *pdev, int source);
	u32 timer_capability;
}

Another benefit from doing this, is that it will simplify the migration of the
dmtimer driver to device-tree. For example, in the current OMAP2+ timer code the
"loses_context" variable is configured at runtime by calling an architecture
specific function. For device tree this creates a problem, because we would need
to call the architecture specific function from within the dmtimer driver.
However, such attributes do not need to be queried at runtime and we can look up
the attributes via HWMOD or device-tree.

This changes a new "capability" variable to the platform data and timer
structure so we can start removing and simplifying the platform data structure.

b7b4ff764f ARM: OMAP2+: Add dmtimer platform function to reserve systimers
During early boot, one or two dmtimers are reserved by the kernel as system
timers (for clocksource and clockevents). These timers are marked as reserved
and the dmtimer driver is notified which timers have been reserved via the
platform data information.

For OMAP2+ devices the timers reserved may vary depending on device and compile
flags. Therefore, it is not easy to assume which timers we be reserved for the
system timers. In order to migrate the dmtimer driver to support device-tree we
need a way to pass the timers reserved for system timers to the dmtimer driver.
Using the platform data structure will not work in the same way as it is
currently used because the platform data structure will be stored statically in
the dmtimer itself and the platform data will be selected via the device-tree
match device function (of_match_device).

There are a couple ways to workaround this. One option is to store the system
timers reserved for the kernel in the device-tree and query them on boot.
The downside of this approach is that it adds some delay to parse the DT blob
to search for the system timers. Secondly, for OMAP3 devices we have a
dependency on compile time flags and the device-tree would not be aware of that
kernel compile flags and so we would need to address that.

The second option is to add a function to the dmtimer code to reserved the
system timers during boot and so the dmtimer knows exactly which timers are
being used for system timers. This also allows us to remove the "reserved"
member from the timer platform data. This seemed like the simpler approach and
so was implemented here.

c3a21fc79b OMAPDSS: fix registration of DPI and SDI devices
The omapdss arch initialization code registers all the output devices as
omap_devices. However, DPI and SDI are not proper omap_devices, as they
do not have any corresponding HWMOD. This leads to crashes or problems
when the platform code tries to use omap_device functions for DPI and
SDI devices.

One such crash was reported by John Stultz <johnstul@us.ibm.com>:

91930652a2 OMAP2+: UART: Add mechanism to probe uart pins and configure rx wakeup
The commit (bce492c0  ARM: OMAP2+: UART: Fix incorrect population of
default uart pads) removed default uart pads that where getting populated
and which was making rx pin wakeup capable. If uart pads were used in
different mode by any other module then it would fail since the default
pads took over all the uart pins forcefully. With removal of default pads
the rx_pad wakeup for console uart while waking up from off mode is broken.

Utilise the mux api available to probe the availability of mux pins
in uart mode and probe for availability of uart pin in mux mode0
if uart is available as uart pin itself then configure rx pin
as wakeup capable.

This patch itself doesn't cater to all boards. Boards using uart rx wakeup
mechanism should ensure the usage of omap_serial_init_port by configuring
required uart ports and pass necessary mux data, till then this probing of
uart pins can cater to enabling of rx pad wakeup to most of the boards.

This patch can also throw some boot warning from _omap_mux_get_by_name
if pin is requested for availability is not present while dynamically probing
the uart pins availability such boot warnings can be addressed only when board
files are patched with omap_serial_init_port calls passing the right pads
needed for a given port.

08f3098928 ARM: OMAP2+: am33xx: Add AM335XEVM machine support
This patch adds minimal support for AM335X machine init.

During last merge window, two separate patches supporting am33xx
machine init had been submitted,

1. Link to earlier Baseport patch submission (Legacy):
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg59325.html
2. Link to earlier DT based machine init support patch submission:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg61398.html

And both had got accepted at that time, but got missed during
merge window.

But now, since we have taken decision to make am33xx as a separate
class and not to follow omap3 family, these patches needs to changes
accordingly (only changes),

 - Combine both the patches, since early init and timer init
   used in board-generic.c file requires them.
 - Remove dependency on AM3517EVM, and only use DT approach
   for machine init.
 - Change the config option (as changed recently)
   CONFIG_SOC_OMAPAM33XX --> CONFIG_SOC_AM33XX

fe57ab0605 ARM: OMAP2: Remove legacy USB FS support
The FS (Full Speed) USB controller is available on 2420 and 2430,
but not being used.

Out of the 2420 based boards only Nokia N8X0 are seeing active
development and they have external HS (High Speed) TUSB controller.
On omap 2430sdp there is MUSB HS controller, so there's no need
to use the legacy USB FS controller.

That leaves only H4 and Apollon boards that could use the FS USB
controller. As both H4 and Apollon boards are old proprietary
development boards, it's unlikely that we have any active
developers working on those boards using the USB.

So remove the FS USB support for omap2 machines. Patches are
welcome if somebody wants to instead fix it all up to the
current standards.

f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

b324c67d48 arm-soc: device tree conversions, part 1
The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of
 booting using device trees, which is a great step forward for them. at91
 and spear have pretty much completed this process with a huge amount of
 work being put into at91. The other platforms are continuing the process.
 
 We finally start to see the payback on this investment, as new machines
 are getting supported purely by adding a .dts source file that can be
 completely independent of the kernel source.

Pull device tree conversions for arm-soc, part 1, from Olof Johansson:
 "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game
  of booting using device trees, which is a great step forward for them.
  at91 and spear have pretty much completed this process with a huge
  amount of work being put into at91.  The other platforms are
  continuing the process.

  We finally start to see the payback on this investment, as new
  machines are getting supported purely by adding a .dts source file
  that can be completely independent of the kernel source."

8d602cf50d ARM: OMAP3: gpmc: add BCH ecc api and modes
This patch adds a simple BCH ecc computation api, similar to the
existing Hamming ecc api. It is intended to be used by the MTD layer.
It implements the following features:

- support 4-bit and 8-bit ecc computation
- do not protect user bytes in spare area, only data area is protected
- ecc for an erased NAND page (0xFFs) is also a sequence of 0xFFs

This last feature is obtained by adding a constant polynomial to
the hardware computed ecc. It allows to correct bitflips in blank pages
and is extremely useful to support filesystems such as UBIFS, which expect
erased pages to contain only 0xFFs.

This api has been tested on an OMAP3630 board.

Artem: The OMAP maintainer Tony Lindgren gave us his blessing for merging
this patch via the MTD tree.

The machine-specific omap2_mbox_startup is called only once
to initialize the whole mbox module, and as a result,
enabling the mbox irq at that point only works for the very first
mailbox instance opened.

Instead, this patch makes sure enable_irq() is called every
time a new mbox instance is opened. In addition, we're now
enabling the mbox's irq only after its notifier_block is registered,
to avoid possible race of receiving an interrupt without invoking
the user's notifier callback.

1ce0299687 arm: omap3: am35x: Don't mark missing features as present
The Chip Identification register on the am35x family of SoCs
has bits 12, 7:5, and 3:2 marked as reserved and are read as
zeroes.  Unfortunately, on other omap SoCs, a 0 bit means a
feature is "Full Use" so the OMAP3_CHECK_FEATURE() macro
called by omap3_check_features() will incorrectly interpret
those zeroes to mean that a feature is present even though it
isn't.  To fix that, the feature bits that are incorrectly
set (namely, OMAP3_HAS_IVA and OMAP3_HAS_ISP) need to be
cleared after all of the calls to OMAP3_CHECK_FEATURE() in
omap3_check_features() are made.

99b59df048 ARM: OMAP3: PM: fix shared PRCM interrupts: leave disabled at boot
By default, request_irq() will auto-enable the requested IRQ.

For PRCM interrupts, we may want to avoid that until the PM core code
is fully ready to handle the interrupts.  This is particularily true
for IO pad interrupts on OMAP3, which are shared between the hwmod
core and the PRM core.

In order to avoid PRCM IO-chain interrupts until the PM core is ready
to handle them, ready, set the IRQ_NOAUTOEN flag for the PRCM IO-chain
interrupt,  which means it will remain disabled after request_irq().

Then, explicitly enable the PRCM interrupts after the request_irq() in
the PM core (but not in the hwmod core.)

Special thanks to Tero Kristo for suggesting to isolate the fix to
only the IO-chain interrupt on OMAP3 instead of all PRCM interrupts.

e3c83c2db4 ARM: OMAP2+: INTC: fix suspend abort, set IRQCHIP_SKIP_SET_WAKE
Without an ->irq_set_wake() method in an irq_chip, calls to
enable_irq_wake() will fail.  This also causes these interrupts to not
be able to abort suspend (via check_wakeup_irqs() in late suspend.)

Currently, we don't implement ->irq_set_wake() for INTC interrupts
because they default to be wakeup enabled by setting the GRPSEL bits
in PM init.  Even though there is no ->irq_set_wake(), we want
enable_irq_wake() to succeed so these interrupts can abort suspend
when necessary.

To fix, set IRQCHIP_SKIP_SET_WAKE flag for all the INTC
interrupts which avoids trying to check irq_chip->irq_set_wake()
and failing when it doesn't exist.

Longer term, we need to implement ->irq_set_wake() for the INTC
which can manage the appropriate GRPSEL bits.

35deca3de6 OMAPDSS: interface drivers register their panel devices
Currently the higher level omapdss platform driver gets the list of
displays in its platform data, and uses that list to create the
omap_dss_device for each display.

With DT, the logical way to do the above is to list the displays under
each individual output, i.e. we'd have "dpi" node, under which we would
have the display that uses DPI. In other words, each output driver
handles the displays that use that particular output.

To make the current code ready for DT, this patch modifies the output
drivers so that each of them creates the display devices which use that
output. However, instead of changing the platform data to suit this
method, each output driver is passed the full list of displays, and the
drivers pick the displays that are meant for them. This allows us to
keep the old platform data, and thus we avoid the need to change the
board files.

53f576a8dc OMAPDSS: create DPI & SDI devices
We currently have separate device/driver for each DSS HW module. The DPI
and SDI outputs are more or less parts of the DSS or DISPC hardware
modules, but in SW it makes sense to represent them as device/driver
pairs similarly to all the other outputs. This also makes sense for
device tree, as each node under dss will be a platform device, and
handling DPI & SDI somehow differently than the rest would just make the
code more complex.

This patch modifies arch/arm/mach-omap2/display.c to create platform
devices for DPI and SDI, and later patches will implement driver for
them.

00928eaf52 OMAPDSS: clean up the omapdss platform data mess
The omapdss pdata handling is a mess. This is more evident when trying
to use device tree for DSS, as we don't have platform data anymore in
that case. This patch cleans the pdata handling by:

- Remove struct omap_display_platform_data. It was used just as a
  wrapper for struct omap_dss_board_info.
- Pass the platform data only to omapdss device. The drivers for omap
  dss hwmods do not need the platform data. This should also work better
  for DT, as we can create omapdss device programmatically in generic omap
  boot code, and thus we can pass the pdata to it.
- Create dss functions for get_ctx_loss_count and dsi_enable/disable_pads
  that the dss hwmod drivers can call.

68a88b9887 ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xx
Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.)  To make it more clear what is
being detected, convert the names from 3517 to AM35xx.

This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

3410773013 ARM: OMAP: AM35xx: remove redunant cpu_is checks for AM3505
There are several checks for AM35x devices done using

      if (cpu_is_omap3517() || cpu_is_omap3505())

However, since the 3505 is just a 3517 without an SGX, the 3505 check
is redundant because cpu_is_omap3517() will always be true whenever
cpu_is_omap3505() is true.  From <plat/cpu.h>:

 #define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx())

Therefore, remove the redunant 3505 checks.  This helps move towards
removal of SoC detection that depends on specific IP detection.

fde0190d69 OMAP4: twl-common: Add twl6030 V1V8, V2V1 SMPS common configuration
V1V8 supply from twl6030 commonly used as VIO for the machine.
V2V1 is adviced to supply the twl6040, and also to feed the twl6030's
VCXIO_IN, and VDAC_IN inputs.
Create the common regulator configurations for these regulators:
Make the V2V1 as supply_regulator for VCXIO, VDAC.
Add twl6040 (1-004b) as consumer for V1V8, and V2V1.

a42cf2c6c6 ARM: OMAP3: igep0020: Add support for Micron NAND Flash storage memory
IGEP-based boards can have two different flash memories, a OneNAND or
a NAND device. The boot configuration pins (sys_boot) are used to
specify which memory is available.

Also, this patch removes unnecesary code for registering the OneNAND.

8259573b32 ARM: OMAP2+: nand: Make board_onenand_init() visible to board code
board_onenand_init() and board_nand_init() initialization functions are
used to initialize OneNAND and NAND memories respectively. But only
board_nand_init() was visible to be used from board code. This patch makes
possible to initialize a OneNAND flash memory within platform code.
