Subject: [PATCH v3 1/2] drm/i915/display/dp: Remove UHBR13.5 for icl
Date: Wed, 02 Apr 2025 14:26:27 +0530	[thread overview]
Message-ID: <20250402-dprates-v3-1-9e5d8ca989dd@intel.com> (raw)
In-Reply-To: <20250402-dprates-v3-0-9e5d8ca989dd@intel.com>

Per Bspec display 14+ has uhbr13.5 Due to the retimer constraint none of
the Intel platforms support uhbr13.5. This has been removed for mtl
by the commit caf3d748f646 ("drm/i915/dp: Remove support for UHBR13.5")
This patch will remove the support for DG2.

v2: Reframed the commit msg (Jani)
