- Austria Microsystem's AS3711
- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader
- Nokia's retu
We also got some notable cleanups and improvements:
- tps6586x got converted to IRQ domains.
- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ

- sta2x11 gained regmap support.
Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
wm5xxx and wm8xxx patchset.

Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some
firmware loading updates and other minor things in the driver core.
All of these have (much to Stephen's annoyance), been in linux-next for
a while.

The twl6030-pwm driver is going to be deleted since it was only able to
control the Charging indicator LED on the twl6030 PMIC.
The new set of drivers are going to provide support for both PWMs and PWM
driven LED outputs on TWL4030 and TWL6030 PMICs.
The twl-pwm driver will handle the PWMs (2 instance) while the twl-pwmled
driver is to control the two LED instance on TWL4030 and to charging
indicator LED (1 instance) on TWL6030.

The correct chip id is 1 since the PWM module is on address 0x49. With the
current TWL6030_MODULE_ID1 the kernel will crash early since we have:
#define TWL6030_MODULE_ID1 0x0E
and
static struct twl_client twl_modules[4];
Down in the stack we try to get the module by:
struct twl_client *twl = &twl_modules[chip];
Which is obviously going to do nasty things.

- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke
compile for non-omap as include plat/cpu.h was added. This header
was indirectly included earlier when SPARSE_IRQ was not set, but
does not exist on most platforms.
Fix the problem by removing the cpu_is_omap usage that should
not exist in drivers at all. We can do this by adding proper
clock aliases for the twl-core.c drivers, and drop separate
handling for cases when clock framework is not available as
the behaviour will stay the same.
Note that we need to add a platform device to avoid using the
i2c provided names that may be different on various omaps.

As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.
Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.
While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.
Note that for drivers/staging/tidspbridge we just define things
locally.

all pretty straightforward, except one thing.
One of our patches added thermal support for power supply class, but
thermal/ subsystem changed under our feet. We (well, Stephen, that is)
caught the issue and it was decided[1] that I'd just delay the battery
pull request, and then will fix it up by merging upstream back into
battery tree at the specific commit.
That's not all though: another[2] small fixup for thermal subsystem was
needed to get rid of a warning in power supply subsystem (the warning
was not drivers/power's "fault", the thermal registration function just
needed a proper const annotation, which is also done by a small commit
on top of the merge.
So, to sum this up:
- The 'master' branch of the battery tree was in the -next tree for
weeks, was never rebased, altered etc. It should be all OK;
- Although, for-v3.6 tag contains the 'master' branch + merge + the
warning fix.

device_init_wakeup uses the dev_name() of the device to set the
name of the wakeup_source which appears in
/sys/kernel/debug/wakeup_sources.
For a platform device, that name is not set until platform_device_add
calls dev_set_name.
So the call to device_init_wakeup() must be after the call to
platform_device_add().
Making this change causes correct names to appear in the
wakeup_sources file.

The charger needs usb3v1 to be running, so add a new consumer to
keep it running.
This allows the charger to draw current even when the USB driver has
powered down.

twl-regulator has a collection of feature flags, some defined
in twl-core.c and one defined in i2c/twl.h.
This is confusing for anyone adding a new feature flag.
So collect them together and place them in twl.h immediately
after the structure in which they are initially set.

During DT adaptation, the irq_alloc_desc was added into twl-core, but
due to the rather different and weird IRQ management required by the twl4030,
it is much better to have a different approach for it.
The issue is that twl4030 uses a two level IRQ mechanism but handles all the
PWR interrupts as part of the twl-core interrupt range. It ends up with a
range of 16 interrupts total for CORE and PWR.
The other twl4030 functionalities already have a dedicated driver and thus
their IRQs and irqdomain can and should be defined localy.
twl6030 is using a single level IRQ controller and thus does not require any
trick.
Move the irq_alloc_desc and irq_domain_add_legacy in twl4030-irq and
twl6030-irq.
Allocate together CORE and PWR IRQs for twl4030-irq.

This has been a fairly quiet release from a regulator point of view, the
only real framework features added were devm support and a convenience
helper for setting up fixed voltage regulators.
We also added a couple of drivers (but will drop the BQ240022 driver via
the arm-soc tree as it's been replaced by the more generic
gpio-regulator driver) and Axel Lin continued his relentless and
generally awesome stream of fixes and cleanups.

In commit aeb5032b3f, a dependency on IRQ_DOMAIN was added, which causes
regressions on previously working setups: a previously working non-DT
kernel configuration now loses its PMIC support. The lack of PMIC
support in turn causes the loss of other functionality the kernel had.
This dependency was added because the driver now registers its
interrupts with the IRQ domain code, presumably to prevent a build error.
The result is that OMAP3 oopses in the vp.c code (fixed by a previous
commit) due to the lack of PMIC support.
However, even with IRQ_DOMAIN enabled, the driver oopses:

This happens because we try to register an IRQ domain with a NULL ops
structure, and the first thing irq_domain_add() does is try to
dereference this ops structure.
So, fix the problem by getting rid of the incorrect OF_IRQ ifdef and
wrapping the IRQ domain bits of the driver with an IRQ_DOMAIN ifdef
instead.

This has been deprecated for considerable time now and support has been
removed from the regulator API. dev_name should be used instead.

Add initial device-tree support for twl familly chips.
The current version is missing the regulator entries due
to the lack of DT regulator bindings for the moment.
Only the simple sub-modules that do not depend on
platform_data information can be initialized properly.
Add irqdomain support.
Add documentation for the Texas Instruments TWL Integrated Chip.

The codec for Devkit8000 (TWL4030) was not detected except
when build with CONFIG_SND_SOC_ALL_CODECS.
twl-core.c still uses the CONFIG_TWL4030_CODEC for
twl_has_codec().
In commit 57fe7251f5
the CONFIG_TWL4030_CODEC was renamed
into CONFIG_MFD_TWL4030_AUDIO, thatswhy the codec
was not detected.
This patch renames the CONFIG_ TWL4030_CODEC into
CONFIG_MFD_TWL4030_AUDIO in twl-core.c.

TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.
TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.
This driver is based on TWL4030 and WM8350 MFD drivers.

Allign the platform data names for twl4030 audio submodule:
twl4030_audio_data: for the core MFD driver
twl4030_codec_data: for ASoC codec driver
twl4030_vibra_data: for the input/ForceFeedback driver
To avoid breakage, change all depending drivers, files
to use the new types.
