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

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

When activating good old Genmai board for regression testing, I found
out that not much is needed to activate the DMA controller for A1L.
Which makes sense, because the driver was initially written for this
SoC. Let it come home ;)

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. Adding SDHI
is still WIP because RZ/A1L usage exposes a SDHI driver bug. So much for
the value of regression testing...
