-* Amlogic Audio PDM input
-
-Required properties:
-- compatible: 'amlogic,axg-pdm' or
- 'amlogic,g12a-pdm' or
- 'amlogic,sm1-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.
-
-Optional property:
-- resets: phandle to the dedicated reset line of the pdm input.
-
-Example of PDM on the A113 SoC:
-
-pdm: audio-controller@...32000 {
- 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";
-};
