1Spreadtrum Multi-Channel Data Transfer Binding
2
3The Multi-channel data transfer controller is used for sound stream
4transmission between audio subsystem and other AP/CP subsystem. It
5supports 10 DAC channel and 10 ADC channel, and each channel can be
6configured with DMA mode or interrupt mode.
7
8Required properties:
9- compatible: Should be "sprd,sc9860-mcdt".
10- reg: Should contain registers address and length.
11- interrupts: Should contain one interrupt shared by all channel.
12
13Example:
14
15mcdt@41490000 {
16	compatible = "sprd,sc9860-mcdt";
17	reg = <0 0x41490000 0 0x170>;
18	interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
19};
