* Rockchip SPDIF Receiver
|
|
The S/PDIF audio block is a stereo receiver that allows the
|
processor to receive and digital audio via an coaxial cable or
|
a fibre cable.
|
|
Required properties:
|
|
- compatible: should be one of the following:
|
- "rockchip,rk3308-spdifrx"
|
- reg: physical base address of the controller and length of memory mapped
|
region.
|
- interrupts: should contain the SPDIF interrupt.
|
- dmas: DMA specifiers for rx dma. See the DMA client binding,
|
Documentation/devicetree/bindings/dma/dma.txt
|
- dma-names: should be "rx"
|
- clocks: a list of phandle + clock-specifier pairs, one for each entry
|
in clock-names.
|
- clock-names: should contain following:
|
- "hclk": clock for SPDIF controller
|
- "mclk" : clock for SPDIF bus
|
- resets: a list of phandle + reset-specifer paris, one for each entry in reset-names.
|
- reset-names: reset names, should include "spdifrx-m".
|
|
Example for the rk3308 SPDIF-RX controller:
|
|
spdif_rx: spdif-rx@ff3b0000 {
|
compatible = "rockchip,rk3308-spdifrx";
|
reg = <0x0 0xff3b0000 0x0 0x1000>;
|
interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
|
clocks = <&cru SCLK_SPDIF_RX>, <&cru HCLK_SPDIFRX>;
|
clock-names = "mclk", "hclk";
|
dmas = <&dmac1 14>;
|
dma-names = "rx";
|
resets = <&cru SRST_SPDIFRX_M>;
|
reset-names = "spdifrx-m";
|
status = "disabled";
|
};
