-ST-Ericsson COH 901 318 DMA Controller
-
-This is a DMA controller which has begun as a fork of the
-ARM PL08x PrimeCell VHDL code.
-
-Required properties:
-- compatible: should be "stericsson,coh901318"
-- reg: register locations and length
-- interrupts: the single DMA IRQ
-- #dma-cells: must be set to <1>, as the channels on the
-  COH 901 318 are simple and identified by a single number
-- dma-channels: the number of DMA channels handled
-
-Example:
-
-dmac: dma-controller@c00020000 {
-	compatible = "stericsson,coh901318";
-	reg = <0xc0020000 0x1000>;
-	interrupt-parent = <&vica>;
-	interrupts = <2>;
-	#dma-cells = <1>;
-	dma-channels = <40>;
-};
-
-Consumers example:
-
-uart0: serial@c0013000 {
-	compatible = "...";
-	(...)
-	dmas = <&dmac 17 &dmac 18>;
-	dma-names = "tx", "rx";
-};
