Merge tag 'v4.8-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next
Pull rockchip clk driver updates from Heiko Stuebner:
Placeholder for the rk3399 watchdog pclk, some newly exported
rk3228 clockids and a small fix for the not yet used spdif to
displayport clock on the rk3399.

+* Amlogic GXBB Clock and Reset Unit
+
+The Amlogic GXBB clock controller generates and supplies clock to various
+controllers within the SoC.
+
+Required Properties:
+
+- compatible: should be "amlogic,gxbb-clkc"
+- reg: physical base address of the clock controller and length of memory
+ mapped region.
+
+- #clock-cells: should be 1.
+
+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/gxbb-clkc.h header and can be
+used in device tree sources.
+
+Example: Clock controller node:
+
+ clkc: clock-controller@c883c000 {
+ #clock-cells = <1>;
+ compatible = "amlogic,gxbb-clkc";
+ reg = <0x0 0xc883c000 0x0 0x3db>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller:
+
+ uart_AO: serial@c81004c0 {
+ compatible = "amlogic,meson-uart";
+ reg = <0xc81004c0 0x14>;
+ interrupts = <0 90 1>;
+ clocks = <&clkc CLKID_CLK81>;
+ status = "disabled";
+ };
