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 = ; };
