Subject: [PATCH 10/11] drm/i915/cnl: Fix DP max rate for Cannonlake with port F.
Date: Fri, 22 Dec 2017 14:23:25 -0800 [thread overview]
Message-ID: <20171222222326.18562-10-rodrigo.vivi@intel.com> (raw)
In-Reply-To: <20171222222326.18562-1-rodrigo.vivi@intel.com>
On CNL SKUs that uses port F, max DP rate is 8.1G for all
ports when we have the elevated voltage.
v2: Make commit message more generic.
