Your patch also drops support for inverters on synchronisation and clock 
lines, I guess, your board doesn't use any. I assume, if any board ever 
needs such inverters, support for them can be added in the future. Also, 
as I mentioned in my reply to your other patch, maybe good to join this 
with #3. Otherwise and with that in mind
