1ST-Ericsson COH 901 318 DMA Controller 2 3This is a DMA controller which has begun as a fork of the 4ARM PL08x PrimeCell VHDL code. 5 6Required properties: 7- compatible: should be "stericsson,coh901318" 8- reg: register locations and length 9- interrupts: the single DMA IRQ 10- #dma-cells: must be set to <1>, as the channels on the 11 COH 901 318 are simple and identified by a single number 12- dma-channels: the number of DMA channels handled 13 14Example: 15 16dmac: dma-controller@c00020000 { 17 compatible = "stericsson,coh901318"; 18 reg = <0xc0020000 0x1000>; 19 interrupt-parent = <&vica>; 20 interrupts = <2>; 21 #dma-cells = <1>; 22 dma-channels = <40>; 23}; 24 25Consumers example: 26 27uart0: serial@c0013000 { 28 compatible = "..."; 29 (...) 30 dmas = <&dmac 17 &dmac 18>; 31 dma-names = "tx", "rx"; 32}; 33
