[v3,01/18] doc: dt-bindings: jz4780-dma: Update bindings to reflect driver changes

[Paul Cercueil]

The driver is now compatible with four SoCs: JZ4780, JZ4770, JZ4725B and
JZ4740.

Besides, it now expects the devicetree to supply a second memory
resource. This resource is mandatory on the newly supported SoCs.
For the JZ4780, new devicetree code must also provide it, although the
driver is still compatible with older devicetree binaries.

What the driver supports is irrelevant to the binding.

So none of these are compatible with each other? It should be one valid 
combination per line.

That's just informative. But I can remove it, no problem.

That's correct - they are all slightly different.
