[PATCH v5 00/14] Clock support for rk3066,rk3188 and rk3288

[Heiko Stübner]

This series adds a clock driver infrastructure for Rockchip SoCs in
general and clock-definitions for the RK3188 and RK3288 in particular.

Apart from the arch/arm patches included here, there are some more
in the waiting line, like adding the i2c nodes and possibly the pwm, i2s
and spi nodes if the relevant drivers get accepted, where the ids
defined in the dt-binding headers are needed.

So if the whole thing is acceptable could we either offer a branch
from the clk-tree that can get merged or take the whole series through
the arm tree?


changes since v4.2:
- fix uninitialized compiler warning in patch4
- add cleanup patch for clk-composite from Mike Turquette
- fix some softrst-issues in patch6
changes since v4.1:
- forgot the From override, Boris is the original author
changes since v4:
- address comments from Gabriel Fernandez
  - use abs()
  - init best_rate
changes since v3:
- add rk3288 clock controller
- add reset controller ids
- fix some incorrect values in rk3188-cru and export some more clocks
- fold new rk3066 clock tree into the rk3188 one, as can be easily seen
  the differences are not really big between them
- expand the composite fix description to highlight the underlying issue
changes since v2:
- drop the special cpuclk type until coordinated range changes
  matured, as mentioned in the Samsung cpufreq thread.
- add the patch from Boris BREZILLON that reenables correct rate
  calculations in composite clocks
- change pll handling to better handle the pll output mux and also
  the enabling/disabling of the pll clock
- change core code to handle composite clock branches instead of
  individual basic clock definitions
- use the newly defined GRF syscon instead of mapping a grf register
  individually
changes since v1:
- adapt to apply on current clk-next branch
- add saradc clock
- add rk3188a cru, which has a slightly different handling of one
  pll value (bwadj)
