| 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"; |
| }; |
