Subject: [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).

Icenowy Zheng (5):
  ARM: sun8i: h3: add operating-points-v2 table for CPU
  ARM: sun8i: h2+: add SY8113B regulator used by Orange Pi Zero board
  ARM: sun8i: h3: add SY8113B regulator used by Orange Pi One board
  ARM: sun8i: h3: fix ALL-H3-CC H3 ver VDD-CPUX voltage
  ARM: sun8i: h3: set the cpu-supply to VDD-CPUX on ALL-H3-CC H3 ver

Ondrej Jirman (5):
  dt-bindings: add binding for the SY8106A voltage regulator
  regulator: add support for SY8106A regulator
  ARM: sunxi: h3/h5: Add r_i2c pinmux node
  ARM: sunxi: h3/h5: Add r_i2c I2C controller
  ARM: sun8i: h3: Add SY8106A regulator to Orange Pi PC
