Hi all,

This patch series adds support for the Direct Memory Access Controller
variant in the Renesas R-Car V3U (R8A779A0) SoC, to both DT bindings and
driver.

This has been tested on the Renesas Falcon board, using external SPI
loopback (spi-loopback-test) on MSIOF1 and MSIOF2.

Thanks for your comments!
