This patch adds binding for the jz4740-i2s driver. Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@xxxxxxxxxx> --- The jz4740 is platform only at the moment. But DT support is being added See http://patchwork.linux-mips.org/bundle/paulburton/ci20-v3.20/ V3 changes: Missed out adding dma bindings in required properties. Only put them in example node for V2. V2 changes: Added DMA bindings for later on --- .../bindings/sound/ingenic,jz4740-i2s.txt | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/ingenic,jz4740-i2s.txt diff --git a/Documentation/devicetree/bindings/sound/ingenic,jz4740-i2s.txt b/Documentation/devicetree/bindings/sound/ingenic,jz4740-i2s.txt new file mode 100644 index 0000000..b414333 --- /dev/null +++ b/Documentation/devicetree/bindings/sound/ingenic,jz4740-i2s.txt @@ -0,0 +1,23 @@ +Ingenic JZ4740 I2S controller + +Required properties: +- compatible : "ingenic,jz4740-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"; + +}; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
