The datasheet and manual list them as NC or Reserved. Maybe mention how
you knew
they were available?
Not sure if this deserves to be in the commit message but I can definitely
put together a covering letter with links etc.
I dear to say it belongs right there in the source code, use a multi-line
comment above the SUNXI_FUNCTION(0x4, "spdif")) to explain where the mux
info comes from. someday sooner or later someone is going to compare the
kernel mux table to the datasheet and think "huh, that is not right",
that person will be saved an immense amount of time by simply having a
comment there.
And do NOT say that this will not happen, because I've already done
such a comparison once in the past.
Regards,
Hans
