18c2ecf20Sopenharmony_ciSpreadtrum Multi-Channel Data Transfer Binding 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciThe Multi-channel data transfer controller is used for sound stream 48c2ecf20Sopenharmony_citransmission between audio subsystem and other AP/CP subsystem. It 58c2ecf20Sopenharmony_cisupports 10 DAC channel and 10 ADC channel, and each channel can be 68c2ecf20Sopenharmony_ciconfigured with DMA mode or interrupt mode. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciRequired properties: 98c2ecf20Sopenharmony_ci- compatible: Should be "sprd,sc9860-mcdt". 108c2ecf20Sopenharmony_ci- reg: Should contain registers address and length. 118c2ecf20Sopenharmony_ci- interrupts: Should contain one interrupt shared by all channel. 128c2ecf20Sopenharmony_ci 138c2ecf20Sopenharmony_ciExample: 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_cimcdt@41490000 { 168c2ecf20Sopenharmony_ci compatible = "sprd,sc9860-mcdt"; 178c2ecf20Sopenharmony_ci reg = <0 0x41490000 0 0x170>; 188c2ecf20Sopenharmony_ci interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>; 198c2ecf20Sopenharmony_ci}; 20
