Other platforms (msm) will benefit from sharing the DSC config setup functions. This series moves parts of static DSC config data from the i915 driver to the common helpers to be used by other drivers.
Note: the RC parameters were cross-checked against config files found in DSC model 2021062, 20161212 (and 20150914). The first patch modifies tables according to those config files, while preserving parameter values using the code. I have not changed one of the values in the pre-SCR config file as it clearly looks like a typo in the config file, considering the table E in DSC 1.1 and in the DSC 1.1 SCR. Chances since v2: - Rebased on top of drm-intel-next Chances since v1: - Made drm_dsc_rc_buf_thresh static rather than exporting it - Switched drm_dsc_rc_buf_thresh loop to use ARRAY_SIZE. Added BUILD_BUG_ON's to be sure that array sizes are correct - Fixed rc_parameters_data indentation to be logical and tidy - Fixed drm_dsc_setup_rc_params() kerneldoc - Added a clause to drm_dsc_setup_rc_params() to verify bpp and bpc being set. - Fixed range_bpg_offset programming in calculate_rc_params() - Fixed bpp vs bpc bug in intel_dsc_compute_params() - Added FIXME comment next to the customizations in intel_dsc_compute_params().
