Subject: [PATCH 08/12] drm/dp: add max number of lanes supported
Date: Tue, 3 Jul 2018 11:02:19 +0100 [thread overview]
Message-ID: <1530612152-27555-9-git-send-email-dkos@cadence.com> (raw)
In-Reply-To: <1530612152-27555-1-git-send-email-dkos@cadence.com>
From: Quentin Schulz <quentin.schulz@free-electrons.com>
Currently, a maximum of 4 lanes is supported in DP.
It can be useful to add this maximum so that we can e.g. create arrays
in drivers that can store data for several lanes (e.g.
DP_TRAINING_LANEx_SET).
