1Broadcom DSL/PON BCM63xx Audio I2S controller
2
3Required properties:
4- compatible:     Should be "brcm,bcm63xx-i2s".
5- #address-cells: 32bit valued, 1 cell.
6- #size-cells:    32bit valued, 0 cell.
7- reg:            Should contain audio registers location and length
8- interrupts:     Should contain the interrupt for the controller.
9- clocks:         Must contain an entry for each entry in clock-names.
10                  Please refer to clock-bindings.txt.
11- clock-names:    One of each entry matching the clocks phandles list:
12                  - "i2sclk" (generated clock) Required.
13                  - "i2sosc" (fixed 200MHz clock) Required.
14
15(1) : The generated clock is required only when any of TX and RX
16      works on Master Mode.
17(2) : The fixed 200MHz clock is from internal chip and always on
18
19Example:
20
21		i2s: bcm63xx-i2s {
22			#address-cells = <1>;
23			#size-cells = <0>;
24			compatible = "brcm,bcm63xx-i2s";
25			reg = <0xFF802080 0xFF>;
26			interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
27			clocks = <&i2sclk>, <&osc>;
28			clock-names = "i2sclk","i2sosc";
29		};
