[PATCH v3 0/2] v3u: add support for SDHI

[Wolfram Sang]

Here is the updated series to enable SDHI on V3U. I just updated the
tags, especially the SoB from Saito-san. Because there are no code
changes, I also decided to not update the v3u/devel-v2 branch.

Takeshi Saito (2):
  arm64: dts: renesas: r8a779a0: Add MMC node
  arm64: dts: renesas: falcon: Enable MMC

Yay, glad it will also make it into 5.12! That will be a nice release
for V3U :)
