[PATCH 00/11] clk: rockchip: add a cpu clock-type

This series implements cpu frequency-scaling for Rockchip SoCs.
The whole handling of the armclk frequency changes and therefore
the implementention is very similar to the recent series for
Samsung SoCs from Thomas Abraham.

Tested on a
- rk3066 Marsboard
- rk3188 Radxa Rock
- rk3288 Evaluation board

If applicable, a good split would be patch 6 in a pullable branch
of the clock tree so that arm-soc can pull it in, patches 8-11
through arm-soc and the rest through the clock tree.


Heiko Stuebner (10):
  clk: rockchip: fix rk3066 pll status register location
  clk: rockchip: reparent aclk_cpu_pre to the gpll
  clk: rockchip: make tightly bound armclk child-clocks read-only
  clk: rockchip: add new clock-type for the cpuclk
  clk: rockchip: add binding id for ARMCLK
  clk: rockchip: switch to using the new cpuclk type for armclk
  ARM: dts: rockchip: add operating points and armclk references
  ARM: dts: rockchip: add cpu supplies to boards
  ARM: rockchip: enable cpufreq-related options
  ARM: rockchip: add a cpufreq-cpu0 device
