+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@...90000 {
+	compatible = "sprd,sc9860-mcdt";
+	reg = <0 0x41490000 0 0x170>;
+	interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
+};
