[PATCH v3 0/3] dmaengine: sh: rz-dmac: add r7s72100 support

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

Changes since v2:
* added tags to patches 1 and 3
* reword commit message 2 to make clear 'clocks' are not needed
* 'power-domains' is also not required for RZA1

Thanks to Geert for the tags and for the input!

Trimmed down initial cover-letter:

When activating good old Genmai board for regression testing, I found
out that not much is needed to activate the DMA controller for A1H.

Patch 1 is a generic fix. The other patches are the actual enablement.
A branch with DTS additions for MMCIF can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/genmai-upstreaming

These will be upstreamed once the driver parts are in next.
