Nevermind, looks like my patch had been based on out-of-date
documentation, so the table here is correct.

That said, I noticed that you didn't include an update to the device
tree bindings documentation. I do have that, in addition to a conversion
to the new json-schema format. Do you mind if I resend your two patches
here along with the DT documentatino update that I have? I've also got
the DTS changes for Tegra234 to expose these, which I would also like to
include for completeness.
