Keshava Munegowda 8f2df0147f Revert "mfd: Add omap-usbhs runtime PM support"
This reverts commit 7e6502d577.

Oops are produced during initialization of ehci and ohci
drivers. This is because the run time pm apis are used by
the driver but the corresponding hwmod structures and
initialization is not merged. hence revering  back the
commit id 7e6502d577

Misael Lopez Cruz f19b2823f8 mfd: twl6040: Add initial support
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.

Jorge Eduardo Candelaria a2974732ca TPS65911: Add new irq definitions
TPS65911 adds new interrupt sources, as well as two new registers
to handle them, one for interrupt status and one for interrupt
masking. The added irqs are:

-VMBCH2 - Low and High threshold
-GPIO1-8 - Rising and falling edge detection
-WTCHDG - Watchdog interrupt
-PWRDN	- PWRDN reset interrupt

The code should handle these new registers only when the chip

Abhijeet Dharmapurikar c013f0a56c mfd: Add pm8xxx irq support
Add support for the irq controller in Qualcomm 8xxx pmic. The 8xxx
interrupt controller provides control for gpio and mpp configured as
interrupts in addition to other subdevice interrupts. The interrupt
controller also provides a way to read the real time status of an
interrupt. This real time status is the only way one can get the
input values of gpio and mpp lines.

The fact that we can't actually raise any interrupts doesn't stop us
setting up the IRQs we're exporting. While this isn't actually going
to do anything it allows us to proceed further through device setup
during board bringup and avoids issues with the MFD core not letting
us suppress the configuration of IRQ resources.

This is a snapshot of the current PRCMU firmware API as it looks
right now. The PRCMU firmware is still subject to change. This
also updates the CPUfreq driver to a newer version that will
utilize the new API.

Linus Walleij 650c2a2145 mach-ux500: move the DB8500 PRCMU driver to MFD
We have decided that this function arbiter fits better in the MFD
subsystem. Since we need to concatenate the split header files we move
it basically like this:

mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c
mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h
mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h
mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h

Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.

That allows all MFD sub devices drivers to be MFD agnostic, unless

especially the ones for IPs used by both MFD and non MFD SoCs.

Andres Salomon 15b7cf1416 MFD: allow cs5535-mfd to build on X86 only
Stephen ran into the following build error:

  drivers/mfd/cs5535-mfd.c:30:22: error: asm/olpc.h: No such file or directory

olpc.h exists only on x86 (and in the future, ARM).  Rather than
wrapping the include in an #ifdef, just change cs5535-mfd to only build
on x86.

Bibek Basu 0cb3fcd72c gpio: driver for 42 AB8500 GPIO pins
To get rid of port expanders, the free GPIOs of ab8500
can be used. There are 42 GPIO pins. Out of which 16
are interrupt capable.This patch implements 16 virtual
IRQ mapped to 16 interrupt capable AB8500 GPIOs.

Thomas Gleixner d740f4523b mfd: twl4030: Cleanup interrupt handling
irq_desc checking in a function which is called with that irq
descriptor locked, is pointless. Equally pointless as the irq desc
check in the interrupt service routine. The driver sets those lines
up, so that cant go away magically.

Remove the open coded handler magic and use the proper accessor.

No need to fiddle with irq_desc in the type setting function. The
original value is in irq_data and the core code stores the new setting
when the return value is 0.

This driver needs to be converted to threaded interrupts and buslock.

Remove the pointless irq_desc check in set_type. This function is

Also store the flow type in the chip data structure, so there is no

There is no point in checking irq_desc here, as it _is_ available. The
driver configured those lines, so they cannot go away.

The home brewn disabled/note_interrupt magic can be removed as well by
adding a irq_disable callback which avoids the lazy disable.

MyungJoo Ham 8de6bc7f6b mfd: Add MAX8997/8966 IRQ control
This patch enables IRQ handling for MAX8997/8966 chips.

Please note that Fuel-Gauge-related IRQs are not implemented in this
initial release. The fuel gauge module in MAX8997 is identical to
MAX17042, which is already in Linux kernel. In order to use the
already-existing MAX17042 driver for fuel gauge module in MAX8997, the
main interrupt handler of MAX8997 should relay related interrupts to
MAX17042 driver. However, in order to do this, we need to modify
MAX17042 driver as well because MAX17042 driver does not have any
interrupt handlers for now. We are not going to implement this in this
initial release as it is not crucial in basic operations of MAX8997.

Daniel Drake adfa4bd4a8 mfd: OLPC: Clean up names to match what OLPC actually uses
The cs5535-pms cell doesn't actually need to be cloned, so we can drop that
and simply have the olpc-xo1.c driver use "cs5535-pms" directly.

Also, rename the cs5535-acpi clones to what we actually use for the (currently
out-of-tree) SCI driver.  In the process, that fixes a subtle bug in
olpc-xo1.c which broke powerdown on XO-1s.. olpc-xo1-ac-acpi was a typo, not
something that actually existed.

Andres Salomon fa1df69168 mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to it
Replace mfd_shared_platform_driver_register with mfd_clone_cell.  The
former was called by an mfd client, and registered both a platform driver
and device.  The latter is called by an mfd driver, and registers only a
platform device.

The downside of this is that mfd drivers need to be modified whenever
new clients are added that share a cell; the upside is that it fits
Linux's driver model better.  It's also simpler.

This also converts cs5535-mfd/olpc-xo1 from the old API.  cs5535-mfd
now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to
them via platform drivers.
