Merge branch 'clk-rockchip' into clk-next

Documentation/devicetree/bindings/clock/rockchip,rk3188-cru.txt

+* 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>;
