Subject: [PATCH v2 1/3] firmware: raspberrypi: Add RPI_FIRMWARE_NOTIFY_DISPLAY_DONE
Date: Fri,  3 Dec 2021 14:51:24 +0100	[thread overview]
Message-ID: <20211203135126.700165-2-maxime@cerno.tech> (raw)
In-Reply-To: <20211203135126.700165-1-maxime@cerno.tech>

The RPI_FIRMWARE_NOTIFY_DISPLAY_DONE firmware call allows to tell the
firmware the kernel is in charge of the display now and the firmware can
free whatever resources it was using.
