Mark Brown 898d8054ec mfd: Correct WM8350 I2C return code usage
The vendor BSP used for the WM8350 development provided an I2C driver
which incorrectly returned zero on succesful sends rather than the
number of transmitted bytes, an error which was then propagated into the
WM8350 I2C accessors.

David Brownell a30d46c042 mfd: twl4030 IRQ handling update
- Move it into a separate file; clean and streamline it
 - Restructure the init code for reuse during secondary dispatch
 - Support both levels (primary, secondary) of IRQ dispatch
 - Use a workqueue for irq mask/unmask and trigger configuration

Code for two subchips currently share that secondary handler code.
One is the power subchip; its IRQs are now handled by this core,
courtesy of this patch.  The other is the GPIO module, which will
be supported through a later patch.

There are also minor changes to the header file, mostly related
to GPIO support; nothing yet in mainline cares about those.  A
few references to OMAP-specific symbols are disabled; when they
can all be removed, the TWL4030 support ceases being OMAP-specific.

Linus Torvalds 9301975ec2 Merge branch 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]).  The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

David Brownell 9297a0e7e0 mfd: twl4030-core irq simplification
Simplify twl4030 IRQ handling by removing a needless custom flow
handler.  The top level IRQs, from the PIH, are well suited for
handle_simple_irq() ... they can't be acked or masked.

Switching resolves some issues with how IRQs were dispatched.
Notably, abuse of desc->status, IRQ accounting, and handling
of various faults.

In short, use standard genirq code.

Drivers that request_irq() to the PIH will need to pay more
attention to things like setting IRQF_DISABLED (since it's
no longer ignored), and making I2C calls from handlers (you'll
need a lockdep workaround).

David Brownell a603a7fa87 mfd: TWL4030 core driver
This patch adds the core of the TWL4030 driver, which supports
chips including the TPS65950.  These chips are multi-function; see

  http://focus.ti.com/docs/prod/folders/print/tps65950.html

Public specs are in the works.  For now, the block diagram on
the second page of the datasheet is fairly informative.

There are some known issues with this core code.  Most notably,
the IRQ dispatching needs simplification (to use more of genirq),
generalization (integrating support for secondary IRQ dispatch
as well as primary, and removing the build dependency on OMAP),
and then probably updating to leverage threaded IRQ support
(expected to arrive in mainline "soon").

Once the core is in mainline, drivers for other parts of this
chip can follow its lead and start swimming upstream too.

Samuel Ortiz 1c2c30acc5 mfd: have TMIO drivers and subdevices depend on ARM
The TMIO chips are only found (and thus tested) on ARM machines.
Moreover, we don't want the TMIO cells to be built if one of the TMIO
driver is not selected (which indirectly make the TMIO cells drivers
depend on ARM as well).

Ian Molton cbdfb42639 mfd: driver for the TC6387XB TMIO controller.
This patch adds support for the TC6387XB. Unlike other TMIO devices this one
has only one subdevice and no interrupt mux, however using the MFD framework
allows it to share the TMIO MMC driver.
