+
+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>;
