That will be great, - One small caveat on this patch though:

The du_dotclkout0 is named differently in Uli's patch. (Of course I believe my
version is correct, but there is some precedent set it would seem).
Anyway, If Uli's version of the PFC is accepted (Which I'm sure it will be),
then I will have to re-spin this patch with the 'different' "du_clk_out_0" value
in the groups.
