Subject: [PATCH 0/6] MFD: add driver for HiSilicon Hi6421v530 PMIC

This patchset adds driver for HiSilicon Hi6421v530 PMIC.

Mainline kernel already has driver support to a similar chip, Hi6421.
Hi6421 and Hi6421v530 are both from the same vendor, HiSilicon, but
they are at different revisions. They both use the same Memory-mapped
I/O method to communicate with Main SoC. However, they differ quite a
lot in their regulator designs. Eg. they have completely different LDO
voltage points.

In order to enable future extension of Hi6421v530 functionality, a new
mfd driver and regulator driver are added in this patchset. Only header
file hi6421-pmic.h is reused between them. Patch 2 is for just this
purpose.

Patch 3 and 4 adds mfd and regulator driver respectively.
Patch 5 is dts change, it depends and can be applied on hi3660/hikey960
        patchset [1].
Patch 6 enables the relevant config items.
