[PATCH v9 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.

It takes a different approach from the past series: basically,
it moves all IRQ related stuff into a new driver ( hi6421v600-irq),
and the MFD driver (hi6421-spmi-pmic) is now quit simple:
it contains just probe and regmap, which attaches into
two MFD "child" drivers (a regulator driver and an IRQ one).

This series also fixes a sutile bug recently introduced via the
regulator tree (patch 2).

Basically, the SPMI/MFD driver combination already uses the
platform data, but the new patch re-uses it to store a mutex
instead, overlapping the previous usage.

This was unoticed on my past tests, as there were some
unused data at the platform struct, that were big enough
to store a mutex, but when I tried to remove it, it caused
crashes and instability at the board.

Regards,
Mauro
