mfd: wm8994: Set mfd id-base for regulator devs creation to avoid conflicts

2015-01-22T15:56:03+00:00

After commit: 6e3f62f0793e ("mfd: core: Fix platform-device id generation")
We must set the id base when register a duplicate name of mfd_cell.
If not, duplicate filename error was reported.

- sysfs: cannot create duplicate filename '/devices/.../wm8994-ldo'

MFD / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T02:04:12+00:00

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/mfd/.

mfd: wm8994-core: Naturalise cross-architecture discrepancies

2014-02-19T13:30:27+00:00

If we compile the WM8994 for a 64bit architecture we receive the following
warnings:

drivers/mfd/wm8994-core.c: In function ‘wm8994_i2c_probe’:
drivers/mfd/wm8994-core.c:639:19:

mfd: wolfson: Constify struct mfd_cell where possible

2014-01-06T09:13:25+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.

mfd: wm8994: Inline register I/O functions

2013-10-23T15:20:37+00:00

Since the register I/O functions are all simple wrappers for the regmap
equivalents inline them to provide a small code size saving and an example
of good practice.

mfd: wm8994: Remove check for active audio in runtime suspend

2013-07-31T00:04:29+00:00

Since enabling VMID takes a runtime PM reference there is no need to
suppress suspend when doing a runtime suspend. Similarly the digital
inputs and outputs are DAPM widgets and therefore the ASoC core will
be holding a reference for them.

This used to be required when integration with system suspend was being
bodged.

mfd: wm8994: Remove unneeded check for JACKDET

2013-07-31T00:04:23+00:00

The jack detection code holds runtime PM references when required so
there is no need for suspend to do any checks.

mfd: wm8994: Remove duplicate check for active JACKDET

2013-07-01T22:54:39+00:00

Probably the result of a mismerge or rebase failing to notice that the
hunk had already been applied.

mfd: wm8994: Reset device during probe

2013-06-17T22:07:49+00:00

Ensure that the device is in a known good state. This should have little
practical impact as the runtime PM will reset the device shortly after
probe but it's neater.

mfd: wm8994: Add some OF properties

2013-04-18T22:35:21+00:00

Add properties for some of the more important bits of platform data and
fill out the binding document.

Not all of the current platform data is suitable for the sort of fixed
configuration that is done using DT, some of it should have runtime
mechanisms added instead and some is unlikely to ever be used in practical
systems.
