Merge branch 'akpm' (Andrew's patch-bomb)

2012-10-05T18:09:16+00:00

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."

mfd: core: Push irqdomain mapping out into devices

2012-09-15T21:22:04+00:00

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

mfd: Also restore wm8994 GPIO IRQ masks after reset

2012-07-08T22:33:29+00:00

This ensures that if we are using a GPIO as a wake source it continues to
function while we're suspended.

mfd: Use regcache_sync_region() to sync wm8994 GPIO registers on suspend

2012-07-08T22:33:04+00:00

Now we have regcache sync region we can use it to do a more efficient
sync of the pin configuration after we reset the device during suspend.

mfd: Restore wm8994 pin configuration after reset during suspend

2012-07-08T22:16:11+00:00

Ensure that we leave the device with the pins in the expected
configuration if we leave it in reset over suspend, avoiding any
interoperation problems with other devices in the system.
