SAMSUNG Exynos SoC series PMU Registers Properties: - compatible : should contain two values. First value must be one from following list: - "samsung,exynos3250-pmu" - for Exynos3250 SoC, - "samsung,exynos4210-pmu" - for Exynos4210 SoC, - "samsung,exynos4212-pmu" - for Exynos4212 SoC, - "samsung,exynos4412-pmu" - for Exynos4412 SoC, - "samsung,exynos5250-pmu" - for Exynos5250 SoC, - "samsung,exynos5260-pmu" - for Exynos5260 SoC. - "samsung,exynos5410-pmu" - for Exynos5410 SoC, - "samsung,exynos5420-pmu" - for Exynos5420 SoC. second value must be always "syscon". - reg : offset and length of the register set. - #clock-cells : must be <1>, since PMU requires once cell as clock specifier. The single specifier cell is used as index to list of clocks provided by PMU, which is currently: 0 : SoC clock output (CLKOUT pin) - clock-names : list of clock names for particular CLKOUT mux inputs in following format: "clkoutN", where N is a decimal number corresponding to CLKOUT mux control bits value for given input, e.g. "clkout0", "clkout7", "clkout15". - clocks : list of phandles and specifiers to all input clocks listed in clock-names property. Example : pmu_system_controller: system-controller@10040000 { compatible = "samsung,exynos5250-pmu", "syscon"; reg = <0x10040000 0x5000>; #clock-cells = <1>; clock-names = "clkout0", "clkout1", "clkout2", "clkout3", "clkout4", "clkout8", "clkout9"; clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>, <&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>, <&clock CLK_OUT_CPU>, <&clock CLK_XXTI>, <&clock CLK_XUSBXTI>; }; Example of clock consumer : usb3503: usb3503@08 { /* ... */ clock-names = "refclk"; clocks = <&pmu_system_controller 0>; /* ... */ };
