-* SHDMA Device Tree bindings
-
-Sh-/r-mobile and r-car systems often have multiple identical DMA controller
-instances, capable of serving any of a common set of DMA slave devices, using
-the same configuration. To describe this topology we require all compatible
-SHDMA DT nodes to be placed under a DMA multiplexer node. All such compatible
-DMAC instances have the same number of channels and use the same DMA
-descriptors. Therefore respective DMA DT bindings can also all be placed in the
-multiplexer node. Even if there is only one such DMAC instance on a system, it
-still has to be placed under such a multiplexer node.

-* DMA multiplexer
-
-Required properties:
-- compatible:	should be "renesas,shdma-mux"
-- #dma-cells:	should be <1>, see "dmas" property below
-
-Optional properties (currently unused):
-- dma-channels:	number of DMA channels
-- dma-requests:	number of DMA request signals
-
-* DMA controller
-
-Required properties:
-- compatible:	should be "renesas,shdma"
-
-Example:
-	dmac: dma-mux0 {
-		compatible = "renesas,shdma-mux";
-		#dma-cells = <1>;
-		dma-channels = <6>;
-		dma-requests = <256>;
-		reg = <0 0>;	/* Needed for AUXDATA */
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges;
-
-		dma0: shdma@fe008020 {
-			compatible = "renesas,shdma";
-			reg = <0xfe008020 0x270>,
-				<0xfe009000 0xc>;
-			interrupt-parent = <&gic>;
-			interrupts = <0 34 4
-					0 28 4
-					0 29 4
-					0 30 4
-					0 31 4
-					0 32 4
-					0 33 4>;
-			interrupt-names = "error",
-					"ch0", "ch1", "ch2", "ch3",
-					"ch4", "ch5";
-		};
-
-		dma1: shdma@fe018020 {
-			...
-		};
-
-		dma2: shdma@fe028020 {
-			...
-		};
-	};
-
-* DMA client
-
-Required properties:
-- dmas:		a list of <[DMA multiplexer phandle] [MID/RID value]> pairs,
-		where MID/RID values are fixed handles, specified in the SoC
-		manual
-- dma-names:	a list of DMA channel names, one per "dmas" entry
-
-Example:
-	dmas = <&dmac 0xd1
-		&dmac 0xd2>;
-	dma-names = "tx", "rx";
