* Broadcom BCM2835 SoC I2S/PCM module Required properties: - compatible: "brcm,bcm2835-i2s" - reg: A list of base address and size entries: * The first entry should cover the PCM registers * The second entry should cover the PCM clock registers - dmas: List of DMA controller phandle and DMA request line ordered pairs. - dma-names: Identifier string for each DMA request line in the dmas property. These strings correspond 1:1 with the ordered pairs in dmas. One of the DMA channels will be responsible for transmission (should be named "tx") and one for reception (should be named "rx"). Example: bcm2835_i2s: i2s@7e203000 { compatible = "brcm,bcm2835-i2s"; reg = <0x7e203000 0x20>, <0x7e101098 0x02>; dmas = <&dma 2>, <&dma 3>; dma-names = "tx", "rx"; };
