* 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;
};
