[PATCH] mfd: qcom-pm8xxx: Clean up PM8XXX namespace

Hi Linus,

On 10/26/2016 03:10 PM, Linus Walleij wrote:

The Kconfig and file naming for the PM8xxx driver is totally
confusing:

- Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel
  users depending on or selecting either at random.
- A driver file named pm8921-core.c even if it is indeed
  used by the whole PM8xxx family of chips.
- An irqchip named pm8xxx since it was (I guess) realized that
  the driver was generic for all pm8xxx PMICs.

As I may want to add support for PM8901 this is starting to get
really messy. Fix this situation by:

- Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX
  and convert all users, including LEDs Kconfig and ARM defconfigs
  for qcom and multi_v7 to use that single symbol.
- Renaming the driver to qcom-pm8xxx.c to fit along the two
  other qcom* prefixed drivers.
- Rename functions withing the driver from 8921 to 8xxx to
  indicate it is generic.
- Just drop the =m config from the pxa_defconfig, I have no clue
  why it is even there, it is not a Qualcomm platform. (Possibly
  older Kconfig noise from saveconfig.)

I do NOT think it is a good idea to try to split this commit up,
I rather prefer that Lee simply merge it into MFD.

The reason is that files like qcom_defconfig already contain both
the right symbols, but the MFD_PM8921_CORE symbol cannot be removed
until this rename has happened, whereas multi_v7_defconfig needs
it added etc, and this is just a clean nice cut.

Jacek, ARM SoC person: please ACK this patch to get merged into
MFD.
