Merge branch 'clk-rockchip' of git://git.linaro.org/people/mike.turquette/linux into next/soc
This is a dependency for the rk3288 DT updates, the branch should
first get merged through Mike's clk git.
* 'clk-rockchip' of git://git.linaro.org/people/mike.turquette/linux:
ARM: rockchip: Select ARCH_HAS_RESET_CONTROLLER
clk: rockchip: add clock controller for rk3288
dt-bindings: add documentation for rk3288 cru
clk: rockchip: add clock driver for rk3188 and rk3066 clocks
dt-bindings: add documentation for rk3188 clock and reset unit
clk: rockchip: add reset controller
clk: rockchip: add clock type for pll clocks and pll used on rk3066
clk: rockchip: add basic infrastructure for clock branches
clk: composite: improve rate_hw sanity check logic
clk: composite: allow read-only clocks
clk: composite: support determine_rate using rate_ops->round_rate + mux_ops->set_parent
