The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v
capable, and it truthfully reports so in its capabilities. This
alternate voltage is used for driving new "UHS-I" SD cards at their
full speed.
However, what the controller doesn't know is that the motherboard
physically doesn't have a 1.8v supply available, so attempting to
switch to the 1.8v level will result in a situation that cannot be
recovered from without physically replugging the SD card.
Add a device tree flag that can be used on systems like these,
and hook it up to the equivalent SDHCI quirk.

HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.
From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation):
The MMC/SD/SDIO output signals can be driven on either falling edge or
rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows
to reach better timing performance, and thus to increase data transfer
frequency.
There are few pre-requisites for enabling the HSPE bit
- Controller should support High-Speed-Enable Bit and
- Controller should not be using DDR Mode and
- Controller should advertise that it supports High Speed in
capabilities register and
- MMC/SD clock coming out of controller > 25MHz

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

Filenames of devictree binding documentation seems to be arbitrary and
for me it is unneeded hazzle to find the corresponding documentation for
a specific driver.
Naming the description the same as the driver is a lot easier and makes
sense to me since the driver defines the binding it understands.
Also, remove a reference in one source to the binding documentation, since path
information easily gets stale.

pinctrl subsystem needs gpio chip base to prepare set of gpio
pin ranges, which a given pinctrl driver can handle. This is
important to handle pinctrl gpio request calls in order to
program a given pin properly for gpio operation.
As gpio base is allocated dynamically during gpiochip
registration, presently there exists no clean way to pass this
information to the pinctrl subsystem.
After few discussions from [1], it was concluded that may be
gpio controller reporting the pin range it supports, is a
better way than pinctrl subsystem directly registering it.

The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework
and don't support this API anymore.
The i.MX6q sabrelite platform equips an egalax touchscreen controller,
and this platform already transfered to GENERIC_GPIO framework, to
support this driver, we use a more generic way to get gpio.
Add a return value checking for waking up the controller in the probe
function, this guarantee only a workable device can pass init.

Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."

All legacy PWM providers have now been moved to the PWM subsystem. The
plan for 3.8 is to adapt all board files to provide a lookup table for
PWM devices in order to get rid of the global namespace. Subsequently,
users of the legacy pwm_request() and pwm_free() functions can be
migrated to the new pwm_get() and pwm_put() functions. Once this has
been completed, the legacy API and the compatibility code in the core
can be removed.
In addition to the above, these changes also add support for configuring
the polarity of a PWM signal (currently only supported on ECAP and
EHRPWM) and include a much needed rework of the i.MX driver. Managed
functions to obtain and release a PWM device (devm_pwm_get() and
devm_pwm_put()) have been added and the pwm-backlight driver has been
updated to use them. If the PWM subsystem hasn't been enabled, dummy
functions are provided that allow the subsystem to safely compile out.
Some common checks on input parameters have been moved to the core and
removed from the drivers. Finally, a small fix corrects the description
of the PWM specifier's second cell in the device tree representation.

This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to
the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers
- A new driver for DA9055 and the support for regulator bypass mode.

Merge tag 'sound-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support
of D3 clock-stop. Also changing the power_save option in sysfs
kicks off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in
HD-audio are continued cleanups and standardization for the generic
auto parser and bug fixes (HBR, device-specific fixups), in
addition to the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers
- A new driver for DA9055 and the support for regulator bypass mode."
Fix up various arm soc header file reorg conflicts.

clk_{un}prepare is mandatory for platforms using common clock framework.
Since this driver is used by SPEAr platform, which supports common clock
framework, add clk_{un}prepare() support for it.

Pull ARM updates from Russell King:
"This is the first chunk of ARM updates for this merge window.
Conflicts are expected in two files - asm/timex.h and
mach-integrator/integrator_cp.c. Nothing particularly stands out more
than anything else.
Most of the growth is down to the opcodes stuff from Dave Martin,
which is countered by Rob's patches to use more of the asm-generic
headers on ARM."
(A few more conflicts grew since then, but it all looked fairly trivial)

This branch contains updates to OMAP and Marvell platforms (kirkwood,
dove, mvebu) that came in after we had done the big multiplatform merges,
so they were kept separate from the rest, and not separated into the
traditional topics of cleanup/driver/platform features.
For OMAP, the updates are:
- Runtime PM conversions for the GPMC and RNG IP blocks
- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
- OMAP hwmod code and data improvements
- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support
For Kirkwood/Dove/mvebu:
- New driver for "address decoder controller" for mvebu, which
is a piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP since
it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect
nand, mv_cesa and the above address decoder controller.
- Some defconfig updates, mostly to enable new DT boards and a few drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
- New clean gpio driver for mvebu

The second cell in the PWM specifier denotes the period in nanoseconds,
not the duty cycle. The latter can be freely configured at runtime and
a PWM with a fixed duty cycle would be rather pointless.
