Subject: [PATCH v2 3/3] drm/bridge: analogix_dp: remove the panel prepare/unprepare in suspend/resume
Date: Fri, 22 Jul 2016 09:50:53 +0800	[thread overview]
Message-ID: <1469152253-7383-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1469151750-7130-1-git-send-email-ykk@rock-chips.com>

We already manager the panel power status in bridge_disable and
connector->detect functions, then we don't need to manager the
panel power status at suspend/resume in particular.
