Subject: [PATCH 0/6] Convert JZ4740 to dmaengine

Hi,

This series replaces the custom JZ4740 DMA API with a dmaengine driver. This is
done in 3 steps:
	1) Add a dmaengine driver which wraps the custom JZ4740 DMA API
	2) Update all users of the JZ4740 DMA API to use dmaengine instead
	3) Remove the custom API and move all direct hardware access to the
	   dmaengine driver.

The first two patches in the series also make sure that the clock of the DMA
core is enabled.

Since the patches in this series depend on each other I'd prefer if they could
all go through the DMA tree.

There are a few minor changes to the patch 3 in v2 of this series, all other
patches are identical to v1.

- Lars
