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...
