+
+description:
+ The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and
+ supports a Time Division Multiplexed (TDM) interface with external
+ multi-channel audio codecs. It consists of a receiver, a transmitter and a
+ common clock generator that can be enabled separately to provide Adapter,
+ Client or Controller modes with receiver and/or transmitter active.

-* Microchip I2S Multi-Channel Controller
-
-Required properties:
-- compatible: Should be "microchip,sam9x60-i2smcc".
-- reg: Should be the physical base address of the controller and the
- length of memory mapped region.
-- interrupts: Should contain the interrupt for the controller.
-- dmas: Should be one per channel name listed in the dma-names property,
- as described in atmel-dma.txt and dma.txt files.
-- dma-names: Identifier string for each DMA request line in the dmas property.
- Two dmas have to be defined, "tx" and "rx".
-- clocks: Must contain an entry for each entry in clock-names.
- Please refer to clock-bindings.txt.
-- clock-names: Should be one of each entry matching the clocks phandles list:
- - "pclk" (peripheral clock) Required.
- - "gclk" (generated clock) Optional (1).
-
-Optional properties:
-- pinctrl-0: Should specify pin control groups used for this controller.
-- princtrl-names: Should contain only one value - "default".
-
-
-(1) : Only the peripheral clock is required. The generated clock is optional
- and should be set mostly when Master Mode is required.
-
-Example:
-
- i2s@f001c000 {
- compatible = "microchip,sam9x60-i2smcc";
- reg = <0xf001c000 0x100>;
- interrupts = <34 IRQ_TYPE_LEVEL_HIGH 7>;
- dmas = <&dma0
- (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) |
- AT91_XDMAC_DT_PERID(36))>,
- <&dma0
- (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) |
- AT91_XDMAC_DT_PERID(37))>;
- dma-names = "tx", "rx";
- clocks = <&i2s_clk>, <&i2s_gclk>;
- clock-names = "pclk", "gclk";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_i2s_default>;
