Subject: [PATCH 08/14] drm/bridge: analogix_dp: move basic controller init into runtime PM
Date: Fri, 3 May 2024 17:11:23 +0200 [thread overview]
Message-ID: <20240503151129.3901815-9-l.stach@pengutronix.de> (raw)
In-Reply-To: <20240503151129.3901815-1-l.stach@pengutronix.de>
Make sure the controller is in a basic working state after runtime
resume. Keep the analog function enable in the mode set path as this
enables parts of the PHY that are only required to be powered when
there is a data stream being sent out.
