Subject: [PATCH_V3 0/3] dma: dt: Add DMA driver for jz4780
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.
