+Broadcom DSL/PON BCM63xx Audio I2S controller
+
+Required properties:
+- compatible: Should be "brcm,bcm63xx-i2s".
+- #address-cells: 32bit valued, 1 cell.
+- #size-cells: 32bit valued, 0 cell.
+- reg: Should contain audio registers location and length
+- interrupts: Should contain the interrupt for the controller.
+- clocks: Must contain an entry for each entry in clock-names.
+ Please refer to clock-bindings.txt.
+- clock-names: Should be one of each entry matching the clocks phandles list:
+ - "i2sclk" (generated clock) Required.
+ - "i2sosc" (fixed 200MHz clock) Required.
+
+(1) : The generated clock is required only when any of TX and RX
+ works on Master Mode.
+(2) : The fixed 200MHz clock is from internal chip and always on
+
+Example:
+
+ i2s: bcm63xx-i2s {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "brcm,bcm63xx-i2s";
+ reg = <0xFF802080 0xFF>;
+ interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&i2sclk>, <&osc>;
+ clock-names = "i2sclk","i2sosc";
+ };
