[PATCH 1/5] dt-bindings: display: vc4: Add optional phandle to firmware
From: Maxime Ripard <hidden>
Date: 2021-11-17 14:50:58
Also in:
dri-devel, linux-arm-kernel
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for vc4, open firmware and flattened device tree bindings, the rest · Maintainers:

The firmware can free all the resources it was using to run the display engine that won't be needed once the kernel has taken over. Thus, we need a phandle to the firmware DT node to be able to send that message when relevant.
