Subject: [PATCH 0/6] v3u: add SDHI/MMC support

So, this series adds SDHI/MMC support to the Renesas R-Car V3U SoC.
While SDHI is usually complicated, adding basic support to V3U was
refreshingly uncomplicated :) The crux was this time in the CPG driver.
In order to avoid code duplication, a CPG library was introduced, so we
can share the SD clock handling between generic Gen3, V3U, and hopefully
Gen4 later. The library turned out to be a quite nice solution for SDHI.
I am quite happy with it. I think we could have a similar benefit for
RPC, but we still need to see if this is enabled on V3U after all.

So much for now, looking forward to comments. The branch is here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/v3u/sdhi

Happy hacking,

   Wolfram
