Hi Greg,

Those are the remaining patches needed for USB3 to start working on HiKey 970.

I would prefer to have those merged during this cycle, as the PCIe patchset
currently under review depends on patch 1 and 2 of this series.

So, I dropped the cleanup patch from this series, due to a merge conflict with
the regulator's tree. I'll re-submit it against the mfd tree after the merge window. 

Mauro Carvalho Chehab (3):
  mfd: hi6421-spmi-pmic: move driver from staging

This driver is ready for mainstream. So, move it out of staging.

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.
