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

+* Rockchip RK3188/RK3066 Clock and Reset Unit
+
+The RK3188/RK3066 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3188-cru", "rockchip,rk3188a-cru" or
+ "rockchip,rk3066a-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+ If missing pll rates are not changable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3188-cru.h and
+dt-bindings/clock/rk3066-cru.h headers and can be used in device tree sources.
+Similar macros exist for the reset sources in these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "xin32k" - rtc clock - optional,
+ - "xin27m" - 27mhz crystal input on rk3066 - optional,
+ - "ext_hsadc" - external HSADC clock - optional,
+ - "ext_cif0" - external camera clock - optional,
+ - "ext_rmii" - external RMII clock - optional,
+ - "ext_jtag" - externalJTAG clock - optional
+
+Example: Clock controller node:
+
+ cru: cru@20000000 {
+ compatible = "rockchip,rk3188-cru";
+ reg = <0x20000000 0x1000>;
+ rockchip,grf = <&grf>;
+
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller:
+
+ uart0: serial@10124000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0x10124000 0x400>;
+ interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <1>;
+ clocks = <&cru SCLK_UART0>;
