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>;
|
|
};
