1 * Amlogic Audio PDM input
4 - compatible: 'amlogic,axg-pdm' or
6 - reg: physical base address of the controller and length of memory
8 - clocks: list of clock phandle, one for each entry clock-names.
9 - clock-names: should contain the following:
10 * "pclk" : peripheral clock.
11 * "dclk" : pdm digital clock
12 * "sysclk" : dsp system clock
13 - #sound-dai-cells: must be 0.
15 Example of PDM on the A113 SoC:
17 pdm: audio-controller@ff632000 {
18 compatible = "amlogic,axg-pdm";
19 reg = <0x0 0xff632000 0x0 0x34>;
20 #sound-dai-cells = <0>;
21 clocks = <&clkc_audio AUD_CLKID_PDM>,
22 <&clkc_audio AUD_CLKID_PDM_DCLK>,
23 <&clkc_audio AUD_CLKID_PDM_SYSCLK>;
24 clock-names = "pclk", "dclk", "sysclk";
