The jz4780 and jz4740 have very similar i2s blocks. The slight difference is in Rx/Tx fifos. And the bitclocks for input/output are different. This patch adds jz4780 support to the driver Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

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";
|
|
|
|
};
