[PATCH v7 0/8] Move Hisilicon 6421v600 SPMI and USB drivers out of staging

[PATCH v7 0/8] 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 series address the comments made on v5. Sorry for taking so long to
return back on this. Got sidetracked by other unrelated stuff.

v6:

Only patch 3 was changed (*):
- Copyrights changed to "20xx-" in order to indicate just the start date
  of the copyrights;
- HISI_8BITS_MASK is now defined as simply 0xff (without using GENMASK);
- There's no sense to mask the value read by regmap_read() when writing
  it back to acknowledge that IRQs got handled;
- removed one extra tab from the regmap_config identation;
- if irq_create_mapping() fails, return -ENODEV;
- use devm_request_threaded_irq().

(*) as we're using --no-merges, in order to show the full code at renames,
    patch 6 will also look different.

[PATCH v7 7/8] 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.
