Subject: [Intel-gfx] [PATCH] drm/i915/display/adlp: More voltage swing table updates
Date: Tue, 15 Mar 2022 13:51:22 -0700	[thread overview]
Message-ID: <20220315205122.202701-1-jose.souza@intel.com> (raw)

A few more updates in the alderlake-P voltage swing tables.

eDP HBR3 table was the same as icelake one but now it has changes for
voltage 0 and pre-emphasis 2 line.
And DP tables also had one line change in each.

Bspec: 49291
