| * Imagination Technologies I2S controller |
| |
| Required properties: |
| - compatible : Must be "img,i2s". |
| - reg : A list containing the I2S audio-out and audio-in registers |
| and length respectively. |
| - interrupts : Should contain all the interrupts for audio out/in lines. The |
| interrupts for the output channels must be first followed by the input one. |
| - interrupt-names: The interrupt names "output0", "output1", "output2", "input". |
| - clocks : A reference to the I2S clock node. |
| - dmas : DMA client properties as described in img-mdc-dma.txt. The dmas |
| property should contain the DMA phandle along with the DMA peripheral and channel |
| number for each channel starting with the output channels first. |
| |
| Example: |
| |
| i2s: tz1090-i2s@02004f00 { |
| compatible = "img,i2s"; |
| reg = < 0x02004f00 0x100 /* out */ |
| 0x02005000 0x100 /* in */>; |
| interrupts = < 9 4 /* level */ |
| 10 4 /* level */ |
| 11 4 /* level */ |
| 12 4 /* level */>; |
| interrupt-names = "output0", "output1", "output2", "input"; |
| clocks = <&i2sout_sysclk>; |
| dmas = <&dma 9 0xffffffff /* out */ |
| &dma 10 0xffffffff /* in */>; |
| }; |
