[v10,0/5] Move Hisilicon 6421v600 SPMI and USB drivers out of staging

Hi Greg,

This series contain the final bits needed for the USB3 bus to work
without staging drivers on Hikey 970.

Tested on a Hikey 970:

	$ lsusb
	Bus 002 Device 002: ID 0451:8140 Texas Instruments, Inc. TUSB8041 4-Port Hub
	Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
	Bus 001 Device 003: ID 046d:c52b Logitech, Inc. Unifying Receiver
	Bus 001 Device 002: ID 0451:8142 Texas Instruments, Inc. TUSB8041 4-Port Hub
	Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and checked that mouse events are working using evtest:

	...
	Input device ID: bus 0x3 vendor 0x46d product 0xc52b version 0x111
	Input device name: "Logitech USB Receiver Mouse"
	....
	Testing ... (interrupt to exit)
	Event: time 1624640001.871917, type 2 (EV_REL), code 0 (REL_X), value -4
	Event: time 1624640001.871917, type 2 (EV_REL), code 1 (REL_Y), value -3
	Event: time 1624640001.871917, -------------- SYN_REPORT ------------
	Event: time 1624640001.879868, type 2 (EV_REL), code 0 (REL_X), value -5
	Event: time 1624640001.879868, type 2 (EV_REL), code 1 (REL_Y), value -4
	....

v10:
  - Addressed some issues pointed by Axel Lin at the regulator;
  - Removed a now uneeded header file (hi6421-spmi-pmic.h);
  - Addressed a couple of checkpatch warnings and did minor
    cleanups.

Mauro Carvalho Chehab (5):
  staging: hikey9xx: split hi6421v600 irq into a separate driver
  regulator: hi6421v600-regulator: fix platform drvdata
  mfd: hi6421-spmi-pmic: move driver from staging
  dts: hisilicon: add support for the PMIC found on Hikey 970
  dts: hisilicon: add support for USB3 on Hikey 970
