1 * Microchip I2S Multi-Channel Controller
4 - compatible: Should be "microchip,sam9x60-i2smcc".
5 - reg: Should be the physical base address of the controller and the
6 length of memory mapped region.
7 - interrupts: Should contain the interrupt for the controller.
8 - dmas: Should be one per channel name listed in the dma-names property,
9 as described in atmel-dma.txt and dma.txt files.
10 - dma-names: Identifier string for each DMA request line in the dmas property.
11 Two dmas have to be defined, "tx" and "rx".
12 - clocks: Must contain an entry for each entry in clock-names.
13 Please refer to clock-bindings.txt.
14 - clock-names: Should be one of each entry matching the clocks phandles list:
15 - "pclk" (peripheral clock) Required.
16 - "gclk" (generated clock) Optional (1).
19 - pinctrl-0: Should specify pin control groups used for this controller.
20 - princtrl-names: Should contain only one value - "default".
23 (1) : Only the peripheral clock is required. The generated clock is optional
24 and should be set mostly when Master Mode is required.
