[PATCH v5 0/7] Move Hisilicon 6421v600 SPMI and USB drivers out of staging

[Mauro Carvalho Chehab]

Hi Greg,

Those are the remaining patches that are needed for the USB to work
with Hikey970. This is based on the top of next-20210323.

The main change from the previous patch series is that a new patch
was added:
  - staging: hisilicon,hisi-spmi-controller.yaml cleanup schema

It does some changes at the DT binding file, as requested by Rob.

My understanding from the discussions we had, back on Feb, is that
those patches will be merged via the staging tree.

Thanks!
Mauro

[PATCH v5 6/7] dts: hisilicon: add support for the PMIC found on Hikey 970

[Mauro Carvalho Chehab]

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.
