Subject: [PATCH 0/5] Some Allwinner CCU tweaks and basical DVFS support for H3/H2+

This patchset aim to add basical DVFS support for Allwinner H3/H2+ SoCs, they
seem to be nearly the same.

The first patch is a CCU fix for all NKMP-type clocks, not H3 limited. Please
schedule this patch to 4.11 queue, as A33 needs also this patch. It solves the
problem that system hangs when the PLL_CPUX change for the first time.

The second patch allows the PLL_CPUX to change for CPUX clock on H3.

The third patch imports a bunch of new SoCs' compatibles into
cpufreq-dt-platdev driver.

The fourth patch adds several operating points for Allwinner H3/H2+ CPU.

The fifth patch adds the regulator node to Orange Pi Zero board's device
tree.

Icenowy Zheng (5):
  clk: sunxi-ng: prevent NKMP clocks from temporarily get higher freq
  clk: sunxi-ng: allow set parent clock (PLL_CPUX) for CPUX clock on H3
  cpufreq: dt: Add support for some new Allwinner SoCs
  ARM: sun8i: h3: add operating-points-v2 table for CPU
  ARM: sun8i: h2+: add SY8113B regulator used by Orange Pi Zero board
