[PATCH v2 00/10] Allwinner H3 DVFS support

This patchset tries to add DVFS support for Allwinner H3 SoC,
considering two kinds of adjustable regulators used on H3 boards:
SY8106A I2C-controlled regulator and SY8113B regulator (controllable
by GPIO with some special designs on the board), and also taking the
uncontrollable boards into consider.

PATCH 1 and PATCH 2 are for the SY8106A regulator, then PATCH 3 and
PATCH 4 are for the r_i2c bus, which is used by boards with SY8106A
to communicate with the regulator.

PATCH 5 adds the operating points v2 table to the H3 SoC, but with
OPPs higher than 1008MHz temporarily dropped.

Then there's patches for several tested boards: Orange Pi PC (with
SY8106A), Orange Pi One/Zero (with GPIO-adjustable SY8113B) and
ALL-H3-CC (unadjustable).
