1、属性值配置：
- compatible: "rockchip,rk3328-codec" - reg: 设置内置codec的物理基地址，以及寄存器的空间大小； - rockchip,grf: 指向grf; - clocks: 设置codec的clock; - clock-names: 设置clock的名称为"pclk". - spk-depop-time-ms: 设置speak的depop时间；
2、以rk3328为例：
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";
spk-depop-time-ms = 100;
status = "disabled";
};
