    drm/i915: Add DP dpll limit on ironlake and use existing DPLL search function · 4547668a

    For some clocks, the old Ironlake DPLL calculator wold give m/n/p
    combinations that didn't match the spreadsheet of what HW validation
    tests.  Instead, use the G4X DPLL calculator, which does a better job
    at it.
    
    So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS
    on ironlake. At the same time to consider the dpll setting for display port, we
    add the display port DPLL limit on ironlake, which will directly use the
    function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.
