+* Atmel PDMIC driver under ALSA SoC architecture
+
+Required properties:
+- compatible
+ Should be "atmel,sama5d2-pdmic".
+- reg
+ Should contain PDMIC registers location and length.
+- interrupts
+ Should contain the IRQ line for the PDMIC.
+- dmas
+ One DMA specifiers as described in atmel-dma.txt and dma.txt files.
+- dma-names
+ Must be "rx".
+- clock-names
+ Required elements:
+ - "pclk" peripheral clock
+ - "gclk" generated clock
+- clocks
+ Must contain an entry for each required entry in clock-names.
+ Please refer to clock-bindings.txt.
+- atmel,mic-min-freq
+ The minimal frequency that the micphone supports.
+- atmel,mic-max-freq
+ The maximal frequency that the micphone supports.
+
+Optional properties:
+- pinctrl-names, pinctrl-0
+ Please refer to pinctrl-bindings.txt.
+- atmel,model
+ The user-visible name of this sound card.
+ The default value is "PDMIC".
+- atmel,mic-offset
+ The offset that should be added.
+ The range is from -32768 to 32767.
+ The default value is 0.
+
+Example:
+ pdmic@f8018000 {
+ compatible = "atmel,sama5d2-pdmic";
+ reg = <0xf8018000 0x124>;
+ interrupts = <48 IRQ_TYPE_LEVEL_HIGH 7>;

+ clock-names = "pclk", "gclk";

+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_pdmic_default>;
+ atmel,model = "PDMIC @ sama5d2_xplained";
+ atmel,mic-min-freq = <1000000>;
