| * Broadcom BCM2835 SoC I2S/PCM module |
| |
| Required properties: |
| - compatible: "brcm,bcm2835-i2s" |
| - reg: Should contain PCM registers location and length. |
| - clocks: the (PCM) clock to use |
| - 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 0x24>; |
| clocks = <&clocks BCM2835_CLOCK_PCM>; |
| |
| dmas = <&dma 2>, |
| <&dma 3>; |
| dma-names = "tx", "rx"; |
| }; |
