Richard Röjfors 071193ff41 V4L/DVB: mfd: Add timb-radio to the timberdale MFD
This patch addes timb-radio to all configurations of the timberdale MFD.

Connected to the FPGA is a TEF6862 tuner and a SAA7706H DSP, the I2C
board info of these devices is passed via the timb-radio platform data.

Richard Röjfors 8edbede9eb V4L/DVB: mfd: Add support for the timberdale FPGA
The timberdale FPGA is found on the Intel in-Vehicle Infotainment reference board
russelville.

The driver is a PCI driver which chunks up the I/O memory and distributes interrupts
to a number of platform devices for each IP inside the FPGA.

Misael Lopez Cruz d62abe563f OMAP4: PMIC: Add support for twl6030 codec
In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.

For twl6030 audio codec, the following data may be passed:
    - audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
      transition powers codec up. Setting audpwron_gpio to a negative value
      means that codec will use manual power sequence instead of automatic
      sequence
    - naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
      to low when an interrupt (codec ready, plug insertion/removal, etc) is
      detected

However, codec driver can operate if any or none of them are passed.

Uwe Kleine-König 9e2726776d mfd: Near complete mc13783 rewrite
This fixes several things while still providing the old API:

 - simplify and fix locking
 - better error handling
 - don't ack all irqs making it impossible to detect a reset of the
   rtc
 - use a timeout variant to wait for completion of ADC conversion
 - provide platform-data to regulator subdevice (This allows making
   struct mc13783 opaque for other drivers after the regulator driver is
   updated to use its platform_data.)
 - expose all interrupts
 - use threaded irq

After all users in mainline are converted to the new API, some things
(e.g. mc13783-private.h) can go away.

warning as well as a runtime error intended to flag up to users that

Mark Brown 6a6127462e mfd: Mask and unmask wm8350 IRQs on request and free
Bring the WM8350 IRQ API more in line with the generic IRQ API by
masking and unmasking interrupts as they are requested and freed.
This is mostly just a case of deleting the mask and unmask calls
from the individual drivers.

The RTC driver is changed to mask the periodic IRQ after requesting
it rather than only unmasking the alarm IRQ. If the periodic IRQ
fires in the period where it is reqested then there will be a
spurious notification but there should be no serious consequences
from this.

The CODEC drive is changed to explicitly disable headphone jack
detection prior to requesting the IRQs. This will avoid the IRQ
firing with no jack set up.

Amit Kucheria b4ead61e57 mfd: Add support for remapping twl4030-power power states
The <RESOURCE>_REMAP register allows configuration of the <RESOURCE> in case

Allow this property of resources to be configured (through twl4030_resconfig)
and add code to parse these values to program the registers accordingly.

Lars-Peter Clausen 98c2e49030 mfd: Fix pcf50633-regulator drvdata usage
Currently the pcf50633-regulator driver data is set to the pcf50633 core
structure, but the pcf50633-regulator remove handler assumes that it is set to
the regulator device. This patch fixes the issue by accessing the pcf506533
core structure through its parent device and setting the driver data to the
regulator device.

Lars-Peter Clausen 68d641efd8 mfd: Fix memleak in pcf50633_client_dev_register
Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.

Mark Brown 0c7229f93a mfd: Convert WM835x IRQ handling to use a data table
Rather than open coding individual IRQs in each function which
manipulates them store data for IRQs in a table which is then
referenced in the users.

This is a substantial code shrink and should be a performance win in
cases where only a single IRQ goes off at once since instead of
reading four of the second level IRQ registers for each interrupt
we read only the sub-registers which have had an interrupt flagged.

New MFD child to twl4030 MFD device.

Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.

This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.

The platform specific configuration data is passed along to the
child drivers (audio, vibra).

Peter Ujfalusi 0b83ddebc6 MFD: twl4030: add twl4030_codec MFD as a new child to the core
New MFD child to twl4030 MFD device.

Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.

This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.

The platform specific configuration data is passed along to the
child drivers (audio, vibra).

Amit Kucheria 75a7456539 mfd: Print warning for twl4030 out-of-order script loading
When the sleep script is loaded before the wakeup script, there is a
chance that the system might go to sleep before the wakeup script
loading is completed. This will lead to a system that does not wakeup
and has been observed to cause non-booting boards.

Various options were considered to solve this problem, including
modification of the core twl4030 power code to be smart enough to
reorder the loading of the scripts. But it felt too over-engineered.

Hence this patch just warns the DPS script developer so that they may be
reordered in the board-code itself.

Ideally this would be supported by genirq, particularly for the

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

Current implementation is prone to races, this patch attempts to remove all

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.

Russell King 1cef8e4107 mfd: twl4030 irq fixes
The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is
calling the 'unmask' function in a process context. :The mask/unmask/ack
functions are only designed to be called from the IRQ handler code,
or the proper API interfaces found in linux/interrupt.h.

Also there is no need to have IRQ chaining mechanism. The right way to
handle this is to claim the parent interrupt as a standard interrupt
and arrange for handle_twl4030_pih to take care of the rest of the devices.

The keypad driver for the DM355 EVM got slightly broken as it merged,
since it moved from input/keyboard to input/misc and its Kconfig

Philipp Zabel e956a2a87c mfd: asic3: add clock handling for MFD cells
Since ASIC3 has to work on both PXA and S3C and since their
struct clk implementations differ, we can't register out
clocks with the clkdev mechanism (yet?).
For now we have to keep clock handling internal to this
driver and enable/disable the clocks via the
mfd_cell->enable/disable functions.

Daniel Ribeiro 13a09f93d2 mfd: add PCAP driver
The PCAP Asic as present on EZX phones is a multi function device with
voltage regulators, ADC, touch screen controller, RTC, USB transceiver,
leds controller, and audio codec.

It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.

This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).

Thomas Gleixner 516eca2726 drivers/mfd: remove obsolete irq_desc_t typedef
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users and remove the typedef.
