Those values need to be added to the DT binding documentation, or rather
the header file that now defines the constants for that binding.
BTW, I was rather hoping that Hiroshi would have converted the clock
drivers to actually use that header file by now... Then this requirement
would have been a lot more obvious. Hiroshi, are patches for that coming
soon? Paul, if not, are you able to do that?
For reference, include/dt-bindings/clock/tegra*-car.h.
