1 * Broadcom BCM2835 SoC I2S/PCM module
4 - compatible: "brcm,bcm2835-i2s"
5 - reg: A list of base address and size entries:
6 * The first entry should cover the PCM registers
7 * The second entry should cover the PCM clock registers
8 - dmas: List of DMA controller phandle and DMA request line ordered pairs.
9 - dma-names: Identifier string for each DMA request line in the dmas property.
10 These strings correspond 1:1 with the ordered pairs in dmas.
12 One of the DMA channels will be responsible for transmission (should be
13 named "tx") and one for reception (should be named "rx").
