| * 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; |
| }; |
