Subject: [Intel-gfx] [PATCH v5 15/22] drm/i915/dg1: Update voltage swing tables for DP
Date: Fri, 24 Jul 2020 14:39:11 -0700	[thread overview]
Message-ID: <20200724213918.27424-16-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20200724213918.27424-1-lucas.demarchi@intel.com>

From: Matt Roper <matthew.d.roper@intel.com>

DG1's vswing tables are the same for eDP and HDMI but have slight
differences from ICL/TGL for DP.
