Subject: [Intel-gfx] [CI 7/8] drm/i915/dg1: Update comp master/slave relationships for PHYs
Date: Tue,  6 Oct 2020 17:22:09 -0700	[thread overview]
Message-ID: <20201007002210.3678024-7-lucas.demarchi@intel.com> (raw)

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

As with RKL, DG1's PHY C acts as a comp master for PHY D.
