mfd: Use IS_ENABLED(CONFIG_FOO) instead of checking FOO || FOO_MODULE

2016-05-09T07:23:56+00:00

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

mfd: wm8400-core: Delete wm8400_reg_read()

2016-05-09T07:20:45+00:00

There was a static checker warning in wm8400_reg_read() because we were
returning u16 and that can't hold the negative error codes.  The
function isn't used, so let's just delete it.

mfd: wm8400: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:57:03+00:00

Use devm_mfd_add_devices() for MFD devices registration and get
rid of .remove callback to remove MFD child-devices. This is done
by managed device framework.

mfd: Drop owner assignment from i2c_drivers

2015-08-11T14:08:48+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

mfd: wm8400-core: Make mfd_cell array const

accessing dev->platform_data directly.

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.
