435792d934 ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp
omap3isp depends on omap's iommu and will fail to probe if
initialized before it (which always happen if they are builtin).

Make omap's iommu subsys_initcall as an interim solution until
the probe deferral mechanism is merged.

Currently, the "clockevent_next_event" function only works correctly

ddba6c7f7e OMAP1: pass LCD config with omapfb_set_lcd_config()
LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.

This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.

arch/arm/plat-omap/fb.c contains code to alloc omapfb buffers at early

This code isn't currently used by any board, and is anyway something

later patches make old omapfb driver use vram.c.

58e0d6ab02 OMAP: N770: remove HWA742 platform data
In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.

This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.

ef64a54f6e sock: Introduce the SO_PEEK_OFF sock option
This one specifies where to start MSG_PEEK-ing queue data from. When
set to negative value means that MSG_PEEK works as ususally -- peeks
from the head of the queue always.

When some bytes are peeked from queue and the peeking offset is non
negative it is moved forward so that the next peek will return next
portion of data.

When non-peeking recvmsg occurs and the peeking offset is non negative
is is moved backward so that the next peek will still peek the proper
data (i.e. the one that would have been picked if there were no non
peeking recv in between).

The offset is set using per-proto opteration to let the protocol handle
the locking issues and to check whether the peeking offset feature is
supported by the protocol the socket belongs to.

3b61436a79 PCMCIA: sa11x0: shannon: convert to use new irq/gpio management
Convert Shannon socket driver to use the new irq/gpio management.
This is slightly more involved because we have to touch the private
platform header file to modify the GPIO bitmasks to be GPIO numbers.

3ddd4d0c62 ARM: OMAP: fix voltage domain build errors with PM_OPP disabled
The voltage domain code wants the voltage tables, which are in the

causing the following build errors at link time:

e23e8c0690 ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency'
The patch series to re-factor PCI's 'latency timer' setup (re:
http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
remove the ARM specific definition of 'pcibios_max_latency' once such
had been moved into the pci core resulting in ARM related compile
errors -
  drivers/built-in.o:(.data+0x230): multiple definition of
  `pcibios_max_latency'
  arch/arm/common/built-in.o:(.data+0x40c): first defined here
  make[1]: *** [vmlinux.o] Error 1

In the series, patch 2/16 (commit 168c8619fd) converted the ARM
specific version of 'pcibios_set_master()' to a non-inlined version.
This was done in preperation for hosting it up into PCI's core, which
was done in patch 10/16 (commit 96c5590058) of the series (and
where the removal of ARM's 'pcibios_max_latency' was overlooked).

910ba598c8 ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised
Current ARM local timer code registers CPUFREQ notifiers even in case
the twd_timer_setup() isn't called. That seems to be wrong and
would eventually lead to kernel crash on the CPU frequency transitions
on the SOCs where the local timer doesn't exist or broken because of
hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt).

The issue was observed with v3.3-rc3 and building an OMAP2+ kernel
on OMAP3 SOC which doesn't have TWD.

Below is the dump for reference :

97899e555b ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module
On some omaps twl4030_gpio has a callback to try to initialize
the MMC controller. If twl4030_gpio is compiled as a module,
bad things can happen because the callback function starts
calling functions that are supposed to be marked __init:

Kernel panic - not syncing: Attempted to kill the idle task!
twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
gpiochip_add: registered GPIOs 192 to 209 on device: twl4030
Unable to handle kernel paging request at virtual address b82a4c74
...

Additionally if this does not fail, warnings are produced
about trying to register the MMC multiple times.

Fix this by removing __init from omap_mux_get_by_name,
and add checks if omap2_hsmmc_init() is getting called more
than once.

Note that this will get fixed properly later on by splitting
omap2_hsmmc_init into two functions.

6b783f7c5d irq_domain: Remove irq_domain_add_simple()
irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete.  This patch removes the irq_domain_add_simple()
interface.

This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it.  This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

v4: Fixed number of irqs in mx5 gpio code
v2: Updated to pass in host_data pointer on irq_domain allocation.

75294957be irq_domain: Remove 'new' irq_domain in favour of the ppc one
This patch removes the simplistic implementation of irq_domains and enables
the powerpc infrastructure for all irq_domain users.  The powerpc
infrastructure includes support for complex mappings between Linux and
hardware irq numbers, and can manage allocation of irq_descs.

This patch also converts the few users of irq_domain_add()/irq_domain_del()
to call irq_domain_add_legacy() instead.

v3: Fix bug that set up too many irqs in translation range.
v2: Fix removal of irq_alloc_descs() call in gic driver

fee6a3c33a ARM: 7327/1: need to include asm/system.h in asm/processor.h
For files that include asm/processor.h but not asm/system.h:

In this case, smp_mb() is from the cpu_relax() call in the msm putc().

It likely went uncaught when the uncompress.h change went in since the
defconfig didn't enable that code path, but later changes (e76f4750f4:
ARM: debug: arrange Kconfig options more logically) resulted in the
option being on for msm_defconfig and thus exposed it.

8e43a905dd ARM: 7325/1: fix v7 boot with lockdep enabled
Bootup with lockdep enabled has been broken on v7 since b46c0f7465
("ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR").

This is because v7_setup (which is called very early during boot) calls
v7_flush_dcache_all, and the save_and_disable_irqs added by that patch
ends up attempting to call into lockdep C code (trace_hardirqs_off())
when we are in no position to execute it (no stack, MMU off).

Fix this by using a notrace variant of save_and_disable_irqs.  The code
already uses the notrace variant of restore_irqs.

Part of the series to unify the irq remapping mechanisms in the

kernel/irq/irqdomain.c, which will be a lot easier if the structures
are identical.

Where they differ, I've chose to use the powerpc names since there is
a lot more code using those names.

This set of changes are fixing various section mismatch warnings which
look to be completely valid.  Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs.  For
example: calling code marked __init from driver probe __devinit
functions.

Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out.  In the mean time, I think it's
important to have this fixed for correctness.

Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
errors, and more importantly, making them greppable by unwrapping them.

Tony Lindgren has acked all these patches, put them out for testing a
week ago, and I've tested them on the platforms I have.

70d669de73 ARM: omap: resolve nebulous 'Error setting wl12xx data'
It's useful to print the error code when a called function fails so a
diagnosis of why it failed is possible.  In this case, it fails because
we try to register some data for the wl12xx driver, but as the driver
is not configured, a stub function is used which simply returns -ENOSYS.

Let's do the simple thing for -rc and print the error code.

Also, the return code from platform_register_device() at each of these
sites was not being checked.  Add some checking, and again print the
error code.

This should be fixed properly for the next merge window so we don't
issue error messages merely because a driver is not configured.

This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents
it being marked with an __init annotation.

As it calls omap2_hsmmc_init() unconditionally, the only resolution to
this warning is to remove the __init markings from omap2_hsmmc_init()
and its called functions.  This addresses the functions in hsmmc.c.

d5de63f5f8 ARM: omap: preemptively fix section mismatch in omap4_sdp4430_wifi_mux_init()

omap4_sdp4430_wifi_mux_init() is called by an __init marked function,
and only calls omap_mux_init_gpio() and omap_mux_init_signal() which
are both also an __init marked functions.

The only reason this doesn't issue a warning is because the compiler
inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init().

So, lets add the __init annotation to ensure this remains safe should
the compiler choose not to inline.

0bf68f53f1 ARM: omap: fix uninformative vc/i2c configuration error message
On my OMAP4 platform, I'm getting this error message repeated several
times at boot:

omap_vc_i2c_init: I2C config for all channels must match.
omap_vc_i2c_init: I2C config for all channels must match.

This doesn't help identify what the problem is.  Fix this message to
be more informative:

omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0).
omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0).

This allows us to identify which voltage domains have a problem, and
what the I2C configuration state (a boolean, i2c_high_speed) setting
being used actually is.

From this we find that omap4_core_pmic has i2c_high_speed false, but
omap4_iva_pmic and omap4_mpu_pmic both have it set true.

e93bcee00c pinctrl: move generic functions to the pinctrl_ namespace
Since we want to use the former pinmux handles and mapping tables for

refactoring by renaming them from pinmux_* to pinctrl_*.

ChangeLog v1->v2:
- Also rename the PINMUX_* macros in machine.h to PIN_ as indicated
  in the documentation so as to reflect the generic nature of these
  mapping entries from now on.

1e056dddab ARM: OMAP2xxx: PM: fix OMAP2xxx-specific UART idle bug in v3.3
On OMAP2420-based systems, the PM code ignores the state of the UART
functional clocks when determining what idle state to enter.  This
breaks the serial port now that the UART driver's clock behavior can
be controlled via the PM autosuspend timeout.

To fix, remove the special-case idle handling for the UARTs in the
OMAP2420/2430 PM idle code added by commit
4af4016c53 ("OMAP3: PM: UART: disable
clocks when idle and off-mode support").

Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.

The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.

be4b028195 tty: serial: OMAP: block idle while the UART is transferring data in PIO mode
Prevent OMAP UARTs from going idle while they are still transferring
data in PIO mode.  This works around an oversight in the OMAP UART
hardware present in OMAP34xx and earlier: an idle UART won't send a
wakeup when the TX FIFO threshold is reached.  This causes long delays
during data transmission when the MPU powerdomain enters a low-power
mode.  The MPU interrupt controller is not able to respond to
interrupts when it's in a low-power state, so the TX buffer is not
refilled until another wakeup event occurs.

This fix changes the erratum i291 DMA idle workaround.  Rather than
toggling between force-idle and no-idle, it will toggle between
smart-idle and no-idle.  The important part of the workaround is the
no-idle part, so this shouldn't result in any change in behavior.

This fix should work on all OMAP UARTs.  Future patches intended for
the 3.4 merge window will make this workaround conditional on a
"feature" flag, and will use the OMAP36xx+ TX event wakeup support.

Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291
workaround, which led to the development of this approach.

Instead of printing:

print

This should prevent people from thinking the BUG_ON was an

b46c0f7465 ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR
armv7's flush_cache_all() flushes caches via set/way. To
determine the cache attributes (line size, number of sets,
etc.) the assembly first writes the CSSELR register to select a
cache level and then reads the CCSIDR register. The CSSELR register
is banked per-cpu and is used to determine which cache level CCSIDR
reads. If the task is migrated between when the CSSELR is written and
the CCSIDR is read the CCSIDR value may be for an unexpected cache
level (for example L1 instead of L2) and incorrect cache flushing
could occur.

Disable interrupts across the write and read so that the correct
cache attributes are read and used for the cache flushing
routine. We disable interrupts instead of disabling preemption
because the critical section is only 3 instructions and we want
to call v7_dcache_flush_all from __v7_setup which doesn't have a
full kernel stack with a struct thread_info.

This fixes a problem we see in scm_call() when flush_cache_all()
is called from preemptible context and sometimes the L2 cache is
not properly flushed out.

b8b9987ffd ARM: 7320/1: Fix proc_info table alignment
With an admittedly exotic choice of configuration options
(CC_OPTIMIZE_FOR_SIZE, THUMB2, some other size-minimizing ones)
and compiler, the proc_info table can end up being misaligned,
and the kernel being unbootable (Error: unrecognized/unsupported
processor variant).

Forcing the alignement to 4 bytes in the linker script fixes the
issue.

5a97d0ae5b ARM: 7314/1: kuser: consistently use usr_ret for returning from helpers
__kuser_cmpxchg64 has a return path using bx lr to get back to the caller.
This is actually ok since the code in question is predicated on
CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret
macro is probably better.

6d3ec1ae6c ARM: 7302/1: Add TLB flushing for both entries in a PMD
Linux uses two PMD entries for a PTE with the classic page table format,
covering 2MB range. However, the __pte_free_tlb() function only adds a
single TLB flush corresponding to 1MB range covering 'addr'. On
Cortex-A15, level 1 entries can be cached by the TLB independently of
the level 2 entries and without additional flushing a PMD entry would be
left pointing at the wrong PTE. The patch limits the TLB flushing range
to two 4KB pages around the 1MB boundary within PMD.

8130b9d7b9 ARM: 7308/1: vfp: flush thread hwstate before copying ptrace registers
If we are context switched whilst copying into a thread's
vfp_hard_struct then the partial copy may be corrupted by the VFP
context switching code (see "ARM: vfp: flush thread hwstate before
restoring context from sigframe").

This patch updates the ptrace VFP set code so that the thread state is
flushed before the copy, therefore disabling VFP and preventing
corruption from occurring.

247f4993a5 ARM: 7307/1: vfp: fix ptrace regset modification race
In a preemptible kernel, vfp_set() can be preempted, causing the
hardware VFP context to be switched while the thread vfp state is
being read and modified.  This leads to a race condition which can
cause the thread vfp state to become corrupted if lazy VFP context
save occurs due to preemption in between the time thread->vfpstate
is read and the time the modified state is written back.

This may occur if preemption occurs during the execution of a
ptrace() call which modifies the VFP register state of a thread.
Such instances should be very rare in most realistic scenarios --
none has been reported, so far as I am aware.  Only uniprocessor
systems should be affected, since VFP context save is not currently
lazy in SMP kernels.

The problem was introduced by my earlier patch migrating to use
regsets to implement ptrace.

This patch does a vfp_sync_hwstate() before reading
thread->vfpstate, to make sure that the thread's VFP state is not
live in the hardware registers while the registers are modified.

Thanks to Will Deacon for spotting this.

2af276dfb1 ARM: 7306/1: vfp: flush thread hwstate before restoring context from sigframe
Following execution of a signal handler, we currently restore the VFP
context from the ucontext in the signal frame. This involves copying
from the user stack into the current thread's vfp_hard_struct and then
flushing the new data out to the hardware registers.

This is problematic when using a preemptible kernel because we could be
context switched whilst updating the vfp_hard_struct. If the current
thread has made use of VFP since the last context switch, the VFP
notifier will copy from the hardware registers into the vfp_hard_struct,
overwriting any data that had been partially copied by the signal code.

Disabling preemption across copy_from_user calls is a terrible idea, so
instead we move the VFP thread flush *before* we update the
vfp_hard_struct. Since the flushing is performed lazily, this has the
effect of disabling VFP and clearing the CPU's VFP state pointer,
therefore preventing the thread from being updated with stale data on
the next context switch.

97f1040982 Revert "ARM: 7304/1: ioremap: fix boundary check when reusing static mapping"
This reverts commit 3c424f3598.

Joachim Eastwood reports:
| "ARM: 7304/1: ioremap: fix boundary check when reusing static mapping"
| Commit: 3c424f3598 in Linus master
|
| Breaks booting on my custom AT91RM9200 board.
| There isn't any error messages or anything that indicates what goes
| wrong it just stops after; Uncompressing Linux... done, booting the
| kernel.
|
| Reverting it makes my board boot again.

and further debugging reveals:

ioremap: pfn=fffff phys=fffff000 offset=400 size=1000
ioremap: area c3ffdfc0: phys_addr=200000 pfn=200 size=4000
ioremap: found: addr fef74000 => fed73000 => fed73400

Clearly, an area for pfn 0x200, 16K can't ever satisfy a request for pfn
0xfffff.  This happens because the changed if statement becomes:

                if (0x00200 > 0xfffff ||
                    0xfffff000 + 0x400 + 0x1000-1 > 0x00200000 + 0x4000-1)
and therefore:
                if (0x00200 > 0xfffff ||
                    0x000003ff > 0x00203fff)

The if condition fails, and so we _believe_ that the SRAM mapping fits
our request.  Clearly that's totally bogus.

Moreover, the original premise of the 'fix' patch was wrong:
|    The condition checking boundaries of the requested and existing
|    mappings didn't take in-page offset into consideration though,
|    which lead to obscure and hard to debug problems when requested
|    mapping crossed end of the static one.

as the code immediately above this loop does:

        size = PAGE_ALIGN(offset + size);

so 'size' already contains the requested offset into the page.

So, revert the broken 'fix'.

04511a6fae ARM: SAMSUNG: Fix missing api-change from subsys_interface change
Commit 4a858cfc9a (arm: convert sysdev_class to a regular subsystem)
converted the samsung sysdevs into subsys_interface instances.

While the original add-function only had a (struct sys_device *)
parameter, the dev_add from subsys_interface needs
	(struct device *, struct subsys_interface *)
leading to "initialized from incompatible pointer type" warnings.

693cec9755 ARM: SAMSUNG: Fix platform data setup for I2C adapter 0
The common static default_i2c_data structure gets bus_num set by each
s3c_i2c?_set_platdata() call, except for s3c_i2c0_set_platdata(). Thus
if for instance s3c_i2c1_set_platdata() is called prior to
s3c_i2c0_set_platdata() the I2C0 controller has bus_num set to wrong value
of 1, i.e. the one from previous set_platdata call. Fix this by also setting
bus_num for I2C0.

5d3a21990c ARM: S3C6410: Use device names for both I2C clocks
When the S3C64xx CPUs were converted to clkdev mappings were added for the
I2C controllers on them. On S3C6410 a device name is specified for I2C
controller 1 but not for controller 0 which makes the code less robust as
we'll falsely return the clock for controller 0 if there's an error in the
request for controller 1.

Improve things by registering a device name for controller 0 as well. Due
to the fact that we change the numbering for controller 0 depending on if
we've registered controller 1 this requires an ifdef to choose the name.

d82e5190da ARM: OMAP: fix MMC2 loopback clock handling
Currently MMC2 setup code can only enable loopback clock and
relies on reset value for boards that need to have it disabled.
This causes a problem with certain bootloaders that always enable
that clock, resulting with unwanted bootloader dependencies.

Fix this by making it disable the clock if board data says so.

ffa1e4ede4 ARM: OMAP: fix erroneous mmc2 clock change on mmc3 setup
hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which
enables internal clock for MMC2. Currently this function is also called
by code handling MMC3, and if .internal_clock is set in platform data
(by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2
instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to
be done). This breaks 2nd SD slot on pandora.

Fix this by changing hsmmc23_before_set_reg() to only handle MMC2.
Note that this removes .remux() call for MMC3, but no board currently
needs it and it's also not called for MMC4 and MMC5.

just clear both bits and then OR with the desired value

dbc3982ae2 ARM: OMAP2+: timer: Fix crash due to wrong arg to __omap_dm_timer_read_counter
Commit 2f0778af (ARM: 7205/2: sched_clock: allow sched_clock to be
selected at runtime) had a typo for the case when CONFIG_OMAP_32K_TIMER
is not set.

In dmtimer_read_sched_clock(), wrong argument was getting passed to
__omap_dm_timer_read_counter() function call; instead of "&clksrc",
we were passing "clksrc.io_base", which results into kernel crash.

To reproduce kernel crash, just disable the CONFIG_OMAP_32K_TIMER config
option (and DEBUG_LL) and build/boot the kernel.
This will use dmtimer as a kernel clocksource and lead to kernel
crash during boot  -
