--- Comment #33 from jeroen <jeroenk61 at hotmail.com> ---
The PLL struct values are on my system:

pll_in_min=675,
pll_in_max=5000, 
pll_out_min=64800, 
pll_out_max=120000, 
lcd_pll_out_min=0, 
lcd_pll_out_max=120000, 
min_ref_div=2, 
max_ref_div=1023, 
min_post_div=2, 
max_post_div=127, 
min_feedback_div=4, 
max_feedback_div=2047, 
min_frac_feedback_div=0, 
max_frac_feedback_div=9, 
best_vco=0, 
reference_freq=10000, 
reference_div=0, 
post_div=0, 
flags=1040

I guess this means that for 148.5MHz the post_div has to be 5,6,7 or 8? Also if
I understand the code correctly the ref_div is always 2 as the fb fraction is
used?
