-* 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 following:
- - "rockchip,rk3066-i2s": for rk3066
- - "rockchip,px30-i2s", "rockchip,rk3066-i2s": for px30
- - "rockchip,rk3036-i2s", "rockchip,rk3066-i2s": for rk3036
- - "rockchip,rk3188-i2s", "rockchip,rk3066-i2s": for rk3188
- - "rockchip,rk3228-i2s", "rockchip,rk3066-i2s": for rk3228
- - "rockchip,rk3288-i2s", "rockchip,rk3066-i2s": for rk3288
- - "rockchip,rk3328-i2s", "rockchip,rk3066-i2s": for rk3328
- - "rockchip,rk3366-i2s", "rockchip,rk3066-i2s": for rk3366
- - "rockchip,rk3368-i2s", "rockchip,rk3066-i2s": for rk3368
- - "rockchip,rk3399-i2s", "rockchip,rk3066-i2s": for rk3399
-- reg: physical base address of the controller and length of memory mapped
- region.
-- interrupts: should contain the I2S interrupt.
-- 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 the following:
- - "i2s_hclk": clock for I2S BUS
- - "i2s_clk" : clock for I2S controller
-- rockchip,playback-channels: max playback channels, if not set, 8 channels default.
-- rockchip,capture-channels: max capture channels, if not set, 2 channels default.
-
-Required properties for controller which support multi channels
-playback/capture:
-
-- rockchip,grf: the phandle of the syscon node for GRF register.
-
-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>;
- dmas = <&pdma1 0>, <&pdma1 1>;
- dma-names = "tx", "rx";
- clock-names = "i2s_hclk", "i2s_clk";
- clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
- rockchip,playback-channels = <8>;
- rockchip,capture-channels = <2>;
-};

Current dts files with 'i2s' nodes are manually verified. In order to automate this process rockchip-i2s.txt has to be converted to yaml.
