3 The RK3126/RK3128 clock controller generates and supplies clock to various
4 controllers within the SoC and also implements a reset controller for SoC
9 - compatible: should be "rockchip,rk3126-cru" or "rockchip,rk3128-cru"
10   "rockchip,rk3126-cru" - controller compatible with RK3126 SoC.
11   "rockchip,rk3128-cru" - controller compatible with RK3128 SoC.
12 - reg: physical base address of the controller and length of memory mapped
14 - #clock-cells: should be 1.
15 - #reset-cells: should be 1.
19 - rockchip,grf: phandle to the syscon managing the "general register files"
24 preprocessor macros in the dt-bindings/clock/rk3128-cru.h headers and can be
28 External clocks:
32 clock-output-names:
33  - "xin24m" - crystal input - required,
34  - "ext_i2s" - external I2S clock - optional,
35  - "gmac_clkin" - external GMAC clock - optional
37 Example: Clock controller node:
40 		compatible = "rockchip,rk3128-cru";
44 		#clock-cells = <1>;
45 		#reset-cells = <1>;
48 Example: UART controller node that consumes the clock generated by the clock
49   controller:
55 		clock-frequency = <24000000>;
57 		clock-names = "sclk_uart", "pclk_uart";
