[PATCH v2 2/8] drm/i915/dpio: Add per-lane PHY TX register definitons for bxt/glk
Ville Syrjala

Wed Apr 17 15:12:11 UTC 2024
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Add consistent definitions for the per-lane PHY TX registers
on bxt/glk. The current situation is a slight mess with some
registers having a LN0 define, while others have a parametrized
per-lane definition.
v2: Adjust gvt accordingly
