Hi, Here we have three patches that add a DMA driver for the Ingenic JZ4780 SoC. JZ4780 support is still in-flight. See http://patchwork.linux-mips.org/bundle/paulburton/ci20-v3.20/ These are based on 4.0-rc1. Apart from the channel numbers, jz4740 and jz4780 are quite different. The descriptor bit fields are different in a register There is an extra register for stride in jz4780 jz4780 has more/different features in hardware. Hence, we are unable to use the jz4740-dma driver. V2->V3 changes DMA bindings. See patches for details. V1->V2 changes Updates for dmaengine api changes. Add residue support.
