    drm/i915: program WM_LINETIME on Haswell · 1f8eeabf
    Eugeni Dodonov authored
    The line time can be programmed according to the number of horizontal
    pixels vs effective pixel rate ratio.
    
    v2: improve comment as per Chris Wilson suggestion
    
    v3: incorporate latest changes in specs.
    
    v4: move into wm update routine, also mention that the same routine can
    program IPS watermarks. We do not have their enablement code yet, nor
    handle the required clock settings at the moment, so this patch won't
    program those values for now.
