* Rockchip Rk3328 internal codec Required properties: - compatible: "rockchip,rk3328-codec" - reg: physical base address of the controller and length of memory mapped region. - rockchip,grf: the phandle of the syscon node for GRF register. - clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names. - clock-names: should be "pclk". - spk-depop-time-ms: speak depop time msec. Optional properties: - mute-gpios: GPIO specifier for external line driver control (typically the dedicated GPIO_MUTE pin) Example for rk3328 internal codec: codec: codec@ff410000 { compatible = "rockchip,rk3328-codec"; reg = <0x0 0xff410000 0x0 0x1000>; rockchip,grf = <&grf>; clocks = <&cru PCLK_ACODEC>; clock-names = "pclk"; mute-gpios = <&grf_gpio 0 GPIO_ACTIVE_LOW>; spk-depop-time-ms = 100; };
