1 | ADI AXI-SPDIF controller |
2 | ||
3 | Required properties: | |
d1555c40 | 4 | - compatible : Must be "adi,axi-spdif-tx-1.00.a" |
d7b528ef LPC |
5 | - reg : Must contain SPDIF core's registers location and length |
6 | - clocks : Pairs of phandle and specifier referencing the controller's clocks. | |
7 | The controller expects two clocks, the clock used for the AXI interface and | |
8 | the clock used as the sampling rate reference clock sample. | |
9 | - clock-names: "axi" for the clock to the AXI interface, "ref" for the sample | |
10 | rate reference clock. | |
11 | - dmas: Pairs of phandle and specifier for the DMA channel that is used by | |
12 | the core. The core expects one dma channel for transmit. | |
13 | - dma-names : Must be "tx" | |
