-* Rockchip SPDIF transceiver
-
-The S/PDIF audio block is a stereo transceiver that allows the
-processor to receive and transmit digital audio via an coaxial cable or
-a fibre cable.
-
-Required properties:
-
-- compatible: should be one of the following:
- - "rockchip,rk3066-spdif"
- - "rockchip,rk3188-spdif"
- - "rockchip,rk3228-spdif"
- - "rockchip,rk3288-spdif"
- - "rockchip,rk3328-spdif"
- - "rockchip,rk3366-spdif"
- - "rockchip,rk3368-spdif"
- - "rockchip,rk3399-spdif"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- interrupts: should contain the SPDIF interrupt.
-- dmas: DMA specifiers for tx dma. See the DMA client binding,
- Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: should be "tx"
-- 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
-
-Required properties on RK3288:
- - rockchip,grf: the phandle of the syscon node for the general register
- file (GRF)
-
-Example for the rk3188 SPDIF controller:
-
-spdif: spdif@1011e000 {
- compatible = "rockchip,rk3188-spdif", "rockchip,rk3066-spdif";
- reg = <0x1011e000 0x2000>;
- interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
- dmas = <&dmac1_s 8>;
- dma-names = "tx";
- clock-names = "hclk", "mclk";
- clocks = <&cru HCLK_SPDIF>, <&cru SCLK_SPDIF>;
- #sound-dai-cells = <0>;
-};
