[00/10] drm/i915: move DSC RC tables to drm_dsc_helper.c

Message

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.

Dmitry Baryshkov (10):
  drm/i915/dsc: change DSC param tables to follow the DSC model
  drm/i915/dsc: move rc_buf_thresh values to common helper
  drm/i915/dsc: move DSC tables to DRM DSC helper
  drm/i915/dsc: stop using interim structure for calculated params
  drm/display/dsc: use flat array for rc_parameters lookup
  drm/display/dsc: split DSC 1.2 and DSC 1.1 (pre-SCR) parameters
  drm/display/dsc: include the rest of pre-SCR parameters
  drm/display/dsc: add YCbCr 4:2:2 and 4:2:0 RC parameters
  drm/display/dsc: add helper to set semi-const parameters
  drm/msm/dsi: use new helpers for DSC setup
