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: Remove wm8400 custom cache implementation

2012-05-20T15:27:01+00:00

Save a useful amount of code by removing the custom cache implementation
for wm8400 and using the regmap cache. Also simplify things by not
separately reseting the CODEC registers, this is a sufficiently infrequent
operation that we can simply invalidate the entire cache when this happens.

Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

2012-03-28T20:56:35+00:00

Pull MFD changes from Samuel Ortiz:
 - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
   TI's TPS65090 and TPS65217.
 - New variants support (8420, 8520 ab9540), cleanups and bug fixes for
   the abx500 and db8500 ST-E chipsets.
 - Some minor fixes and update for the wm8994 from Mark.
 - The beginning of a long term TWL cleanup effort coming from the TI
   folks.
 - Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997
   drivers.

Fix up trivial conflicts due to duplicate patches and header file
cleanups ( removal etc).

mfd: Use mfd cell platform_data for wm8400 cells platform bits

2011-05-26T17:45:14+00:00

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.
