| 2 | |
| 3 | The Multi-channel data transfer controller is used for sound stream |
| 4 | transmission between audio subsystem and other AP/CP subsystem. It |
| 5 | supports 10 DAC channel and 10 ADC channel, and each channel can be |
| 6 | configured with DMA mode or interrupt mode. |
| 7 | |
| 8 | Required 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 | |
| 13 | Example: |
| 14 | |
| 15 | mcdt@41490000 { |
| 16 | compatible = "sprd,sc9860-mcdt"; |
| 17 | reg = <0 0x41490000 0 0x170>; |
| 18 | interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>; |
| 19 | }; |
