* 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;
|
|
};
