|
||
|
|
|
||
|
|
The Multi-channel data transfer controller is used for sound stream
|
||
|
|
transmission between audio subsystem and other AP/CP subsystem. It
|
||
|
|
supports 10 DAC channel and 10 ADC channel, and each channel can be
|
||
|
|
configured with DMA mode or interrupt mode.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "sprd,sc9860-mcdt".
|
||
|
|
- reg: Should contain registers address and length.
|
||
|
|
- interrupts: Should contain one interrupt shared by all channel.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
mcdt@41490000 {
|
||
|
|
compatible = "sprd,sc9860-mcdt";
|
||
|
|
reg = <0 0x41490000 0 0x170>;
|
||
|
|
interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
};
