* Rockchip I2S controller
|
||||
|
||||
The I2S bus (Inter-IC sound bus) is a serial link for digital
|
||||
audio data transfer between devices in the system.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: should be one of the followings
|
||||
- "rockchip,rk3066-i2s": for rk3066
|
||||
- "rockchip,rk3188-i2s", "rockchip,rk3066-i2s": for rk3188
|
||||
- "rockchip,rk3288-i2s", "rockchip,rk3066-i2s": for rk3288
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
- interrupts: should contain the I2S interrupt.
|
||||
- #address-cells: should be 1.
|
||||
- #size-cells: should be 0.
|
||||
- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
|
||||
Documentation/devicetree/bindings/dma/dma.txt
|
||||
- dma-names: should include "tx" and "rx".
|
||||
- clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
|
||||
- clock-names: should contain followings:
|
||||
- "i2s_hclk": clock for I2S BUS
|
||||
- "i2s_clk" : clock for I2S controller
|
||||
|
||||
Example for rk3288 I2S controller:
|
||||
|
||||
i2s@ff890000 {
|
||||
compatible = "rockchip,rk3288-i2s", "rockchip,rk3066-i2s";
|
||||
reg = <0xff890000 0x10000>;
|
||||
interrupts = <GIC_SPI 85 IRQ_TYPE_LEVEL_HIGH>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
dmas = <&pdma1 0>, <&pdma1 1>;
|
||||
dma-names = "rx", "tx";
|
||||
clock-names = "i2s_hclk", "i2s_clk";
|
||||
clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
|
||||
};
