0c73b992dd input: Add support for the WM831x ON pin
The WM831x series of PMICs support control of initial power on
through the ON pin on the device with soft control of the pin
at other times. Represent this to userspace as KEY_POWER.

08bad5a821 hwmon: WM831x PMIC hardware monitoring driver
This driver adds support for the hardware monitoring features of
the WM831x PMICs to the hwmon API. Monitoring is provided for
the system voltages supported natively by the WM831x, the chip
temperature, the battery temperature and the auxiliary inputs
of the WM831x.

Currently no alarms are supported, though digital comparators on
the WM831x devices would allow these to be provided.

Since the auxiliary and battery temperature input scaling depends
on the system configuration the value is reported as a voltage to
userspace.

e4b736f18f gpio: Add WM831X GPIO driver
Add support for the GPIO pins on the WM831x. No direct support is
currently supplied for configuring non-gpiolib functionality such
as pull configuration and alternate functions, soft configuration
of these will be provided in a future patch.

Currently use of these pins as interrupts is not supported due to
the ongoing issues with generic irq not support interrupt controllers
on interrupt driven buses. Users can directly request the interrupts
with the wm831x-specific APIs currently provided if required.

698659d5f7 mfd: Export ISEL values from WM831x core
The current settings which can be used with the WM831x current sinks
can't easily be mapped between register values and currents at run
time without a lookup table since the values scale logarithmically
to match the way the human eye interprets brightness. This lookup
table is inclided in the core since several drivers need to use it.

6704e5171b mfd: Add basic WM831x OTP support
The WM831x series of devices use OTP (One Time Programmable, a type
of PROM) to store system configuration. At run time this data is
visible via registers.

Currently the only explicitly supported feature is that the unique
ID provided by every WM831x device is exported to user space via
sysfs. Other configuration data may be read by system-specific
code in the pre_init() and post_init() platform data operations.

63aed85e35 mfd: Conditionally add WM831x backlight subdevice
The WM831x backlight driver requires at least the specification of the

will actively interfere with other users of the regulators it uses if
misconfigured so only register the subdevice for it if this platform
data has been supplied.

7e9f9fd4b8 mfd: Add WM831x AUXADC support
The WM831x contains an auxiliary ADC with a number of switchable
inputs which is used to monitor some of the voltages and
temperatures in the system and has some external inputs which can be
used for machine specific purposes. Provide an API allowing drivers
to read values from the ADC.

An internal reference voltage is provided to allow callibration of
the ADC. This is used to calibrate the device at startup.

The hardware also supports continuous readings and digital comparators.
These are not yet supported by the driver.

7d4d0a3e73 mfd: Add WM831x interrupt support
The WM831x includes an interrupt controller managing interrupts for
the various functions on the chip. This patch adds support for the
core interrupt block on the device.

Ideally this would be supported by genirq, particularly for the
GPIOs, but currently genirq is unable to cope with controllers on
interrupt driven buses so we cut'n'paste the generic interface.
Once genirq is able to cope chips like this it should be a case
of filing the prefixes off the code and redoing wm831x-irq.c to
move over.

3bed6e415f mfd: Allow multiple MFD cells with the same name
Provide basic support for MFDs having multiple cells of a given
type with different IDs by adding an id to the mfd_cell structure
and then adding that to the id passed in to mfd_add_devices().

As it stands this approach requires that MFDs using this feature
deal with ensuring that there aren't any ID collisions resulting
from multiple MFDs of the same type being instantiated. This needs
to happen with the existing code too, but with this approach there
is a knock on effect on the IDs for non-duplicated devices.

89a99e76f6 mfd: Correct ro and cd implemantion on DM355
This patch corrects the support for MMCSD card detection
and read only feature for SoC DM355.

EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that
Bit 2 and 4 should be checked for card detection. However
on the EVM, bits 1 and 3 gives this status, for MMC/SD
instance 0 and 1 respectively. The pdf also suggests that
Bit 1 and 3 should be checked for write protection. However
on the EVM bits 2 and 4 gives this status.

bd8ef10261 mfd: revise locking for pcf50633 ADC
Current implementation is prone to races, this patch attempts to remove all
but one (in pcf50633_adc_sync_read).

The idea is that we need to guard the queue access only on inserting and
removing items. If we insert and there're no more items in the queue it
means that the last irq already happened and we need to trigger ADC
manually. If not, then the next conversion will be triggered by the irq
handler upon completion of the previous.

ed52e62ebe mfd: use a dedicated workqueue for pcf50633 irq processing
Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.

I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

7dbefe3d58 Staging: rt3090: remove possible conflict with rt2860
Both drivers (rt2860 and rt3090) register themselves as "rt2860" on
loading the module.

In the very rare case of somebody having two cards in his machine, one
using rt3090 and the other one using the rt2860 driver, loading both
modules would be impossible, the second one will not be loaded as the
kernel will tell you that the driver is already registered.

This was also present with rt2870/rt3070 (with both driver registering
as "rt2870"), but the code has been merged to one driver recently.

The follwoing patch fixes this potential problem until merging of
rt2860/rt3090 code to a single driver.

18526c7896 Staging: rtl8192e: Drop unnecessary NULL test
The result of container_of should not be NULL.  In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.

A simplified version of the semantic patch that makes this change is as
follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
identifier fn,work,x,fld;
type T;
expression E1,E2;
statement S;
@@

static fn(struct work_struct *work) {
  ... when != work = E1
  x = container_of(work,T,fld)
  ... when != x = E2
- if (x == NULL) S
  ...
}
// </smpl>
