Thanks for your patch!
Unfortunately this is a duplicate of
https://www.spinics.net/lists/devicetree/msg246988.html.
Sorry for stepping on your toes, I added MSIOF support for Ebisu to investigate
MSIOF driver bugs.

The SPI subsystem no longer needs aliases.
Furthermore, aliases complicate DT overlay handling.

This clock does not exist.
Board DTS should use "assigned-clocks" and "assigned-clock-rates" on the
MSO clock instead.

The DMA portions seem new.
Perhaps a new patch should be constructed that only adds those properties?
