[PATCH_V4 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.

These are based on 4.0-rc4.

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.

V3->V4
some minor fixes.
driver would default to 4 byte transfer size in case of unsupported.
now gives error instead

V2->V3 changes
DMA bindings. See patches for details.

V1->V2 changes
Updates for dmaengine api changes.
Add residue support.
Details in the patch commit message
