This doesn't seem right; the "alt" settings should be assigned in order
non-alt, alt1, alt2, alt3.
You say, "the table parsing code couldn't find a matching entry for
VI_ALT3". What was looking for that entry?
Also, shouldn't the pinmux driver be fixed not to write garbage to a
register, but instead return an error, if it can't find the table entry
it's looking for?
