Subject: [PATCH v3 2/2] drm/i915/display/dp: Remove the uhbr13.5 pll state values
Date: Wed, 02 Apr 2025 14:26:28 +0530	[thread overview]
Message-ID: <20250402-dprates-v3-2-9e5d8ca989dd@intel.com> (raw)
In-Reply-To: <20250402-dprates-v3-0-9e5d8ca989dd@intel.com>

uhbr13.5 is not supported on dg2/mtl. This patch removes the pll state
table for synps and c20 PHY.
