[PATCH RESEND v4 v5 1/4] firmware: raspberrypi: Add RPI_FIRMWARE_NOTIFY_DISPLAY_DONE

Maxime Ripard maxime at cerno.tech
Wed Dec 15 01:51:14 PST 2021


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.
