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: 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";
};
