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"?

I had checked schematics for this and they seem to show that this is
vin-supply = <&vcc3v3_sys>?

Maybe its just me, but seems odd that DCDC_REG5 is out of order with the
other DCDC regulators above.

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.
