-* 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";
-};
