Add support for Intel MSIC chip found on Intel Medfield platforms. This
chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The
driver creates platform device for each subdevice.We also provide an MSIC register access API which should replace the more
generic SCU IPC interface currently used. Existing drivers can choose
whether they convert to this new API or stick with the SCU IPC interface.Signed-off-by: Mika Westerberg

In order to ease system integration provide a simulation of active high
IRQs on the GPIOs by polling the GPIO status when an IRQ is generated.This isn't ideal on several fronts and will miss initially active IRQs in
the current implementation but it should work well for most cases.Signed-off-by: Mark Brown

A led subdevice is registered now iff the corresponding platform data is
available. Without platform data the device isn't usable so this is a

TWL6030 devices have an interrupt line which is connected to
application processor like OMAP. These devices support multiple features
such as MMC card detect, USB cable detect, RTC interrupt, etc. that must
wake up the application processor.With this change, TWL6030 client drivers can make use of
irq_wake() if the wakeup is desirable on it's irq events.Signed-off-by: Santosh Shilimkar

In systems where there is no hardware signal from the processor to the
PMIC to initiate the final power off sequence we must initiate the
shutdown with a register write to the PMIC. Support such systems in the
driver. Since this may prevent a full shutdown of the system platform
data is used to enable the feature.Signed-off-by: Mark Brown

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 57fe7251f5bfc4332f24479376de48a1e8ca6211
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.Signed-off-by: Thomas Weber

We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.Signed-off-by: Arnd Bergmann

This is the first step to also support the touch interface of the mc13892

Signed-off-by: Samuel Ortiz -
This is needed to convert the touch driver away from using struct mc13783.
Note this patch drops MC13783_ADC0_ADREFMODE. This is unused and doesn't
exist on mc13892.Signed-off-by: Uwe Kleine-König

- Support wake-up from suspend-to-ram.
- Handle pending interrupt after a resume.
- If pdata->wakeup is enabled, by default, the device is assumed to be
capable of wakeup (the interrupt pin is connected to a wakeup-source GPIO)
and may wakeup the system (MAX8997 has a power button input pin).Signed-off-by: MyungJoo Ham

Enhancements to the WM8994 audio driver and new features on more modern
devices in the series mean that we can no longer rely on VMID being active
as an indication that the device is active. Add further checks for digital

In systems where the LDO enables are always driven (for example, being
connected to an always on supply rail or a GPIO which is driven by the
CPU even in suspend) then we can disable the pull downs on the LDO for

I was trying to fix the error handling part because in the case of
request_irq failure, it should call kthread_stop instead of free_irq.
But it seems more reasonable to do request_irq before calling kthread_run.Signed-off-by: Axel Lin

Refactor the GPADC interface to avoid bugs in calling code:
- ab8500_gpadc_[convert|read_raw|ad_to_voltage] clarifies
each functions use case, *convert wraps *read_raw, and we
can access raw ADC values properly.
- Renamed gpadc function arguments from "input" to "channel" to
clarify use, so we don't get confused again.Signed-off-by: Kalle Komierowski

The mfd/asic3 driver did not define the suspend/resume handlers for the mmc cell
driver. Consequently the mmc driver did not resume properly after returning from
suspend, making sd cards unusable and preventing suspend from being entered a
