|
|
|
|
Required Properties:
|
|
|
|
- compatible : Compatible list, must contain "img,parallel-out".
|
|
|
|
- #sound-dai-cells : Must be equal to 0
|
|
|
|
- reg : Offset and length of the register set for the device.
|
|
|
|
- dmas: Contains an entry for each entry in dma-names.
|
|
|
|
- dma-names: Must include the following entry:
|
|
"tx"
|
|
|
|
- clocks : Contains an entry for each entry in clock-names.
|
|
|
|
- clock-names : Includes the following entries:
|
|
"sys" The system clock
|
|
"ref" The reference clock
|
|
|
|
- resets: Contains a phandle to the parallel out reset signal
|
|
|
|
- reset-names: Contains the reset signal name "rst"
|
|
|
|
Optional Properties:
|
|
|
|
- interrupts : Contains the parallel out interrupt, if present
|
|
|
|
Example:
|
|
|
|
parallel_out: parallel-out@18100C00 {

|
compatible = "img,parallel-out";
|
|
reg = <0x18100C00 0x100>;
|
|
interrupts = <GIC_SHARED 19 IRQ_TYPE_LEVEL_HIGH>;
|
|
dmas = <&mdc 16 0xffffffff 0>;
|
|
dma-names = "tx";
|
|
clocks = <&cr_periph SYS_CLK_PAUD_OUT>,
|
|
<&clk_core CLK_AUDIO_DAC>;
|
|
clock-names = "sys", "ref";
