| * Amlogic Audio PDM input |
| |
| Required properties: |
| - compatible: 'amlogic,axg-pdm' or |
| 'amlogic,g12a-pdm' |
| - reg: physical base address of the controller and length of memory |
| mapped region. |
| - clocks: list of clock phandle, one for each entry clock-names. |
| - clock-names: should contain the following: |
| * "pclk" : peripheral clock. |
| * "dclk" : pdm digital clock |
| * "sysclk" : dsp system clock |
| - #sound-dai-cells: must be 0. |
| |
| Example of PDM on the A113 SoC: |
| |
| pdm: audio-controller@ff632000 { |
| compatible = "amlogic,axg-pdm"; |
| reg = <0x0 0xff632000 0x0 0x34>; |
| #sound-dai-cells = <0>; |
| clocks = <&clkc_audio AUD_CLKID_PDM>, |
| <&clkc_audio AUD_CLKID_PDM_DCLK>, |
| <&clkc_audio AUD_CLKID_PDM_SYSCLK>; |
| clock-names = "pclk", "dclk", "sysclk"; |
| }; |
