Subject: [RFC PATCH 02/11] drm/fb-helper: Skip writeback connectors
Date: Tue, 11 Oct 2016 15:53:59 +0100 [thread overview]
Message-ID: <1476197648-24918-3-git-send-email-brian.starkey@arm.com> (raw)
In-Reply-To: <1476197648-24918-1-git-send-email-brian.starkey@arm.com>
Writeback connectors aren't much use to the fbdev helpers, as they won't
show anything to the user. Skip them when looking for candidate output
configurations.
