Mark Brown ebe38f80b2 mfd: wm8994: Remove check for active audio in runtime suspend
Since enabling VMID takes a runtime PM reference there is no need to
suppress suspend when doing a runtime suspend. Similarly the digital
inputs and outputs are DAPM widgets and therefore the ASoC core will
be holding a reference for them.

This used to be required when integration with system suspend was being
bodged.

Mark Brown 4dd0b2ba1d mfd: wm8994: Remove unneeded check for JACKDET
The jack detection code holds runtime PM references when required so
there is no need for suspend to do any checks.

Mark Brown f3799e9372 mfd: wm8994: Reset device during probe
Ensure that the device is in a known good state. This should have little
practical impact as the runtime PM will reset the device shortly after
probe but it's neater.

Mark Brown 20fb277250 mfd: wm8994: Add some OF properties
Add properties for some of the more important bits of platform data and
fill out the binding document.

Not all of the current platform data is suitable for the sort of fixed
configuration that is done using DT, some of it should have runtime
mechanisms added instead and some is unlikely to ever be used in practical
systems.

Mark Brown 6394678e6e mfd: wm8994: Don't use system PM operations
For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

Jingoo Han 222bc784dc mfd: wm8994: Silence bogus warning in wm8994_device_init()
'patch_regs' cannot be used uninitialized in wm8994_device_init(),
because 'patch_regs' was already guarded by 'regmap_patch'.
Thus, that's a bogus warning.

Without this patch, the build warning happens as below:

drivers/mfd/wm8994-core.c: In function 'wm8994_i2c_probe':
drivers/mfd/wm8994-core.c:595:7: warning: 'patch_regs' may be used uninitialized in this function [-Wuninitialized]

Linus Torvalds 2dfea3803d This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub devices
 drivers:
 
 - 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
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

Mark Brown 0848c94fb4 mfd: core: Push irqdomain mapping out into devices
Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

Pull MFD changes from Samuel Ortiz:
 - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
   TI's TPS65090 and TPS65217.
 - New variants support (8420, 8520 ab9540), cleanups and bug fixes for
   the abx500 and db8500 ST-E chipsets.
 - Some minor fixes and update for the wm8994 from Mark.
 - The beginning of a long term TWL cleanup effort coming from the TI
   folks.
 - Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997
   drivers.

Fix up trivial conflicts due to duplicate patches and header file
cleanups (<linux/device.h> removal etc).

Linus Torvalds 9586c959bf Things are really quieting down with the regmap API, while we're still
seeing a trickle of new features coming in they're getting much smaller
 than they were.  It's also nice to have some features which support
 other subsystems building infrastructure on top of regmap.  Highlights
 include:
 
 - Support for padding between the register and the value when
   interacting with the device, sometimes needed for fast interfaces.
 - Support for applying register updates to the device when restoring the
   register state.  This is intended to be used to apply updates supplied by
   manufacturers for tuning the performance of the device (many of which
   are to undocumented registers which aren't otherwise covered).
 - Support for multi-register operations on cached registers.
 - Support for syncing only part of the register cache.
 - Stubs and parameter query functions intended to make it easier for other
   subsystems to build infrastructure on top of the regmap API.
 
 plus a few driver updates making use of the new features which it was
 easier to merge via this tree.
