[PATCH v8 00/14] Move Hisilicon 6421v600 SPMI and USB drivers out of staging

Hi Greg/Mark/Lee/Vinod,

Another rebase , also the top of staging-testing.

This series contain the remaining patches for USB to start working,
except for a final DTS patch.

Patches 1 and 2 convert the SPMI and regulator
drivers to use regmap and simplifies the logic by using
regmap helpers.

Patches 3 to 9 address some issues pointed by Lee at the MFD driver.

I guess the best would be if Greg could apply patches 1 to 9
via the staging tree.

Patches 10 to 13 move the drivers and their corresponding
DT documentation bindings out of staging.

Patch 14 contains the DT which describes the regulator,
SPMI controller and MFD.

I'll submit the final patch with USB bindings after having
everything set (e.g. after 5.12-rc1).

-

v8: contains a fix for REGMAP dependencies and for a build breakage.

Add a device tree for the HiSilicon 6421v600 SPMI PMIC, used
on HiKey970 board.

As we now have support for it, change the fixed regulators
used by the SD I/O to use the proper LDO supplies.
