* Amlogic Meson8, Meson8b and Meson8m2 Clock and Reset Unit The Amlogic Meson8 / Meson8b / Meson8m2 clock controller generates and supplies clock to various controllers within the SoC. Required Properties: - compatible: must be one of: - "amlogic,meson8-clkc" for Meson8 (S802) SoCs - "amlogic,meson8b-clkc" for Meson8 (S805) SoCs - "amlogic,meson8m2-clkc" for Meson8m2 (S812) SoCs - #clock-cells: should be 1. - #reset-cells: should be 1. Parent node should have the following properties : - compatible: "amlogic,meson-hhi-sysctrl", "simple-mfd", "syscon" - reg: base address and size of the HHI system control register space. 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/meson8b-clkc.h header and can be used in device tree sources. Similarly a preprocessor macro for each reset line is defined in dt-bindings/reset/amlogic,meson8b-clkc-reset.h (which can be used from the device tree sources). Example: Clock controller node: clkc: clock-controller { compatible = "amlogic,meson8b-clkc"; #clock-cells = <1>; #reset-cells = <1>; }; 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>; };
