* Amlogic Audio PDM input
Required properties:
- compatible: 'amlogic,axg-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";
};
