[Intel-gfx] [PATCH v2 0/7] drm/i915: refactor KBL/TGL/ADLS stepping scheme

[Jani Nikula]

This cleans up the split display and gt stepping schemes in
KBL/TGL/ADLS, and makes it easier to extend for future platforms.

We could switch legacy platforms over too, but that would require arrays
to convert to the symbolic step enums, for no real benefit, but with the
drawback of having to maintain the arrays and potentially failing to
handle undefined revids in revid ranges properly.

Jani Nikula (7):
  drm/i915: remove unused ADLS_REVID_* macros
  drm/i915: split out stepping info to a new file
  drm/i915: add new helpers for accessing stepping info
  drm/i915: switch KBL to the new stepping scheme
  drm/i915: switch TGL and ADL to the new stepping scheme
  drm/i915: rename DISP_STEPPING->DISPLAY_STEP and GT_STEPPING->GT_STEP
  drm/i915: rename disp_stepping->display_step and gt_stepping->gt_step
