Subject: [PATCH RESEND v4 v5 1/4] firmware: raspberrypi: Add RPI_FIRMWARE_NOTIFY_DISPLAY_DONE
Date: Wed, 15 Dec 2021 10:51:14 +0100 [thread overview]
Message-ID: <20211215095117.176435-2-maxime@cerno.tech> (raw)
In-Reply-To: <20211215095117.176435-1-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.
Acked-by: Nicolas Saenz Julienne <nsaenz@kernel.org>
