Oh yea sorry about the confusion, have too many separate issues listed 
under this thread. :P That was definitely for Christoph.

For the DSS clk rate part, Tomi should answer that as it seems to come 
from some display driver changes. This might be caused by the infamous 
rounding issues with the clk_set_rate / clk_round_rate and the hackery 
around it in display driver...
