On a system with a USB3317 ULPI transceiver the following message
is shown on kernel boot:
ULPI transceiver vendor/product ID 0x0424/0x0006
Found SMSC USB3319 ULPI transceiver.
ULPI integrity check: passed.
The reason is that USB3317 has the same vendor/product ID as USB3319.
Make the ULPI ID generic for the USB331x transceivers.

Added the TWL6030-usb transceiver option in the Kconfig

Adding the twl6030-usb transceiver support for OMAP4 musb driver.
OMAP4 supports 2 types of transceiver interface.
1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.
There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.
The internal transceiver has functional clocks and
powerdown bits to powerdown the PHY for power saving.
Since there is no option available for having 2 transceiver drivers
for one USB controller, internal PHY specific APIs are passed through
plaform_data function pointers to use in the twl6030-usb transceiver
driver.
2. ULPI interface is provided for off-chip transceivers.

Function twl4030_usb_remove can cause unbalanced regulator disables in
twl4030_phy_power if the cable is not connected. Regulator enable/disable
calls are in balance only if the twl4030_phy_resume was called prior the
twl4030_usb_remove, that is, the cable was connected.
Fix this by checking the 'asleep' variable in twl4030_usb_remove since that
variable is used to check state in other functions.

Commit 461c317705eca5cac09a360f488715927fd0a927(into 2.6.36-v3)
is put forward to power down phy if no usb cable is connected,
but does introduce the two issues below:
1), phy is not into work state if usb cable is connected
with PC during poweron, so musb device mode is not usable
in such case, follows the reasons:
-twl4030_phy_resume is not called, so
regulators are not enabled
i2c access are not enabled
usb mode not configurated
2), The kernel warings[1] of regulators 'unbalanced disables'
is caused if poweron without usb cable connected
with PC or b-device.
This patch fixes the two issues above:
-power down phy only if no usb cable is connected with PC
and b-device
-do phy initialization(via __twl4030_phy_resume) if usb cable
is connected with PC(vbus event) or another b-device(ID event) in
twl4030_usb_probe.
This patch also doesn't put VUSB3V1 LDO into active mode in
twl4030_usb_ldo_init until VBUS/ID change detected, so we can
save more power consumption than before.
This patch is verified OK on Beagle board either connected with
usb cable or not when poweron.

The reset state of twl4030-usb is not sleeping, it starts
up awaken and we need to disable it if we have booted
with a disconnected cable to avoid over consumption on
the default state.
To avoid problems later, we read the current state of the
transceiver from the PHY_PWR_CTRL register. The bootloader
can, anyways, put the device to sleep before us.

ulpi_set_vbus and ulpi_set_flags are using ULPI_SET(register) to write
to the PHY's registers, which means we can only set bits in the PHY's
register and not clear them.
By directly using the address of the register without any offset, we
now get the expected behaviour for these functions.

this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

With CONFIG_USB_ULPI=y, CONFIG_USB<=m, CONFIG_PCI=n and

the build for all mx3 platforms fails because drivers/usb/otg/ulpi.c
where otg_ulpi_create is defined is not compiled.
Build error:

when USB regulators are in enabled state: 3v1, 1v5, 1v8
On a USB cable attach, twl4030_phy_resume(twl) function enables
the regulators. Enable USB charging, only after all regulators
are enabled.
Its observed that enabling USB charging before regulators are
enabled, causes USB charging to fail.

This patch fixes the .probe failure of twl4030_usb driver if
it is compiled into kernel.
Since twl4030_usb USB transceiver .probe depends on
twl4030-regulator, marking twl4030_usb_init as subsys_initcall_sync
can make it called after twl4030-regulator initialization is finished,
then twl4030_usb USB transceiver driver can be probed successfully.

Description:
This driver is used for Intel Langwell* USB OTG controller in Intel
Moorestown* platform. It tries to implement host/device role switch
according to OTG spec. The actual hsot and device functions are
accomplished in modified EHCI driver and Intel Langwell USB OTG client
controller driver.
* Langwell and Moorestown are names used in development. They are not
approved official name.
Note:
This patch is the first version Intel Langwell USB OTG Transceiver
driver. The development is not finished, and the bug fixing is on going
for some hardware and software issues. The main purpose of this
submission is for code view.
Supported features:
- Data-line Pulsing SRP
- Support HNP to switch roles
- PCI D0/D3 power management support
Known issues:
- HNP is only tested with another Moorestown platform.
- PCI D0/D3 power management support is not fully tested.
- VBus Pulsing SRP is not support in current version.

Fix a reporting glitch in the twl4030 USB transceiver code.
It wasn't properly distinguishing the two types of active
USB link: ID grounded, vs not. In the current code that
distinction doesn't much matter; in the future this bugfix
should help support better USB controller communications.
Provide a comment sorting out some of the cryptic bits of
the manual: different sections use different names for
key signals, and the register definitions don't help much
without the explanations and diagrams.

A pointer to twl4030_usb_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
