what made you decide between demoting and completing comments?
I.e. here you demot the "static void rk3x_i2c_stop()", while below
you for example complete the "static rk3x_i2c_get_spec()".

So I somehow do not yet see the pattern ;-)

Completeness.  This one is missing parameter descriptions, the one I
provided the function name to below, is otherwise complete.
