Please try the attached patch.
We now always use the fixed reference divider if both RADEON_PLL_USE_REF_DIV and RADEON_PLL_USE_FRAC_FB_DIV are set.
If only RADEON_PLL_USE_REF_DIV is set then we only use the fixed value as minimum limit.
Does that make sense? Wouldn't we want to use use the fixed value if RADEON_PLL_USE_REF_DIV regardless of whether RADEON_PLL_USE_FRAC_FB_DIV is set?
