Kernel-4.18.0-80.el8_ingenic,jz4740-i2s

Ingenic JZ4740 I2S controller

Required properties:

• compatible : “ingenic,jz4740-i2s” or “ingenic,jz4780-i2s”
• reg : I2S registers location and length
• clocks : AIC and I2S PLL clock specifiers.
• clock-names: “aic” and “i2s”
• dmas: DMA controller phandle and DMA request line for I2S Tx and Rx channels
• dma-names: Must be “tx” and “rx”

Example:

i2s: i2s@10020000 {
compatible = “ingenic,jz4740-i2s”;
reg = <0x10020000 0x94>;

clocks = <&cgu JZ4740_CLK_AIC>, <&cgu JZ4740_CLK_I2SPLL>;
clock-names = "aic", "i2s";

dmas = <&dma 2>, <&dma 3>;
dma-names = "tx", "rx";

};
