* 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@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"; };
