Subject: [PATCH v2 10/20] drm/i915/dp: Fix the link service IRQ DPCD_REV check
Date: Wed, 25 Feb 2026 18:27:41 +0200 [thread overview]
Message-ID: <20260225162751.1255913-11-imre.deak@intel.com> (raw)
In-Reply-To: <20260225162751.1255913-1-imre.deak@intel.com>
From: Imre Deak <imre.deak@gmail.com>
The DP_LINK_SERVICE_IRQ_VECTOR_ESI0 DPCD register is supported only
since DPCD REV 1.2, so fix the revision check accordingly.
