Subject: [Intel-gfx] [CI 12/18] drm/i915/dg2: Skip shared DPLL handling
Date: Wed, 21 Jul 2021 15:30:37 -0700	[thread overview]
Message-ID: <20210721223043.834562-13-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210721223043.834562-1-matthew.d.roper@intel.com>

DG2 has no shared DPLL's or DDI clock muxing.  The Port PLL is embedded
within the PHY.
