+* 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.
