I already submitted patches to remove the clock-names reference from
the other two boards you noted [1]. I agree it should match the
driver and not the schematic. That line was a left-over from our
internal git repo where the decision was used to follow the schematic
and not the driver.
Thanks for bringing that to my attention.
