In addition, the calculations for initial_scale_value and det_thresh_flatness that are defined within the DSC 1.2 specifications, but aren't yet included in drm_dsc_helper.c. This series moves these calculations to a shared msm_dsc_helper.c file and defines drm_dsc_helper methods for initial_scale_value and det_thresh_flatness. Note: For now, the MSM specific helper methods are only called for the DSI path, but will called for DP once DSC 1.2 support for DP has been added.
