| Imagination Technologies I2S Input Controller |
| |
| Required Properties: |
| |
| - compatible : Compatible list, must contain "img,i2s-in" |
| |
| - #sound-dai-cells : Must be equal to 0 |
| |
| - reg : Offset and length of the register set for the device |
| |
| - clocks : Contains an entry for each entry in clock-names |
| |
| - clock-names : Must include the following entry: |
| "sys" The system clock |
| |
| - dmas: Contains an entry for each entry in dma-names. |
| |
| - dma-names: Must include the following entry: |
| "rx" Single DMA channel used by all active I2S channels |
| |
| - img,i2s-channels : Number of I2S channels instantiated in the I2S in block |
| |
| Optional Properties: |
| |
| - interrupts : Contains the I2S in interrupts. Depending on |
| the configuration, there may be no interrupts, one interrupt, |
| or an interrupt per I2S channel. For the case where there is |
| one interrupt per channel, the interrupts should be listed |
| in ascending channel order |
| |
| - resets: Contains a phandle to the I2S in reset signal |
| |
| - reset-names: Contains the reset signal name "rst" |
| |
| Example: |
| |
| i2s_in: i2s-in@18100800 { |
| compatible = "img,i2s-in"; |
| reg = <0x18100800 0x200>; |
| interrupts = <GIC_SHARED 7 IRQ_TYPE_LEVEL_HIGH>; |
| dmas = <&mdc 30 0xffffffff 0>; |
| dma-names = "rx"; |
| clocks = <&cr_periph SYS_CLK_I2S_IN>; |
| clock-names = "sys"; |
| img,i2s-channels = <6>; |
| #sound-dai-cells = <0>; |
| }; |
