3 The RK3328 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,rk3328-cru"
10 - reg: physical base address of the controller and length of memory mapped
12 - #clock-cells: should be 1.
13 - #reset-cells: should be 1.
17 - rockchip,grf: phandle to the syscon managing the "general register files"
22 preprocessor macros in the dt-bindings/clock/rk3328-cru.h headers and can be
26 External clocks:
30 clock-output-names:
31  - "xin24m" - crystal input - required,
32  - "clkin_i2s" - external I2S clock - optional,
33  - "gmac_clkin" - external GMAC clock - optional
34  - "phy_50m_out" - output clock of the pll in the mac phy
35  - "hdmi_phy" - output clock of the hdmi phy pll - optional
37 Example: Clock controller node:
39 	cru: clock-controller@ff440000 {
40 		compatible = "rockchip,rk3328-cru";
44 		#clock-cells = <1>;
45 		#reset-cells = <1>;
48 Example: UART controller node that consumes the clock generated by the clock
49   controller:
52 		compatible = "snps,dw-apb-uart";
55 		reg-shift = <2>;
56 		reg-io-width = <4>;
