Subject: [PATCH 2/7] drm/bridge_connector: Set default status connected for eDP connectors
Date: Wed, 8 Apr 2020 23:11:15 +0200 [thread overview]
Message-ID: <20200408211120.1407512-3-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20200408211120.1407512-1-enric.balletbo@collabora.com>
In an eDP application, HPD is not required and on most bridge chips
useless. If HPD is not used, we need to set initial status as connected,
otherwise the connector created by the drm_bridge_connector API remains
in an unknown state.
