Subject: [PATCH 02/14] drm/rockchip: analogix_dp: add runtime PM handling
Date: Fri, 3 May 2024 17:11:17 +0200 [thread overview]
Message-ID: <20240503151129.3901815-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20240503151129.3901815-1-l.stach@pengutronix.de>
Hook up the runtime PM suspend/resume paths to make the rockchip
glue behave more like the exynos one. The same suspend/resume
functions are used for system sleep via the runtime PM force
suspend/resume.
