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";
|
|
};
