I suppose these mismatched aliases are here to keep compatibility with the Odroid M1? However thats going to be super confusing to anyone following the actual Odroid M1S connector pinout (even the pin card that came with my Odroid M1S doesnt show these mappings, but the actual real ports)?

This compatible seems to be from the Rockchip kernel, for mainline it should be  "tcs,tcs4525"?

Did you miss pmuio1 and vccio2 here? the latter of which is the eMMC domain.

Are you planning to add additional patches for usb, gmac etc? I had been working through cleaning up these device tree files with a view to submitting them soon also.
