ZTE ZX296702 I2S controller Required properties: - compatible : Must be one of: "zte,zx296718-i2s", "zte,zx296702-i2s" "zte,zx296702-i2s" - reg : Must contain I2S core's registers location and length - clocks : Pairs of phandle and specifier referencing the controller's clocks. - clock-names: "wclk" for the wclk, "pclk" for the pclk to the I2S interface. - dmas: Pairs of phandle and specifier for the DMA channel that is used by the core. The core expects two dma channels for transmit. - dma-names : Must be "tx" and "rx" For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties please check: * resource-names.txt * clock/clock-bindings.txt * dma/dma.txt Example: i2s0: i2s@b005000 { #sound-dai-cells = <0>; compatible = "zte,zx296718-i2s", "zte,zx296702-i2s"; reg = <0x0b005000 0x1000>; clocks = <&audiocrm AUDIO_I2S0_WCLK>, <&audiocrm AUDIO_I2S0_PCLK>; clock-names = "wclk", "pclk"; interrupts = ; dmas = <&dma 5>, <&dma 6>; dma-names = "tx", "rx"; }; sound { compatible = "simple-audio-card"; simple-audio-card,name = "zx296702_snd"; simple-audio-card,format = "left_j"; simple-audio-card,bitclock-master = <&sndcodec>; simple-audio-card,frame-master = <&sndcodec>; sndcpu: simple-audio-card,cpu { sound-dai = <&i2s0>; }; sndcodec: simple-audio-card,codec { sound-dai = <&acodec>; }; };
