Subject: [PATCH 16/18] drm/arc: Initialize sim connector before display pipe
Date: Fri, 17 Jul 2020 11:04:28 +0200 [thread overview]
Message-ID: <20200717090430.1146256-16-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200717090430.1146256-1-daniel.vetter@ffwll.ch>
That way we can get rid of this final piece of init code, and use the
simple pipe helpers as intended.
