-Spreadtrum Multi-Channel Data Transfer Binding
-
-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>;
-};
