From 3daa0b6436b9593f6ff5a2082cc8e2f6e3462841 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 23 Jun 2021 11:48:35 +0200 Subject: [PATCH] dt-bindings: display: vc4: Add phandle to the firmware The vc4 driver will need to tell the firmware that it takes over the display for the firmware to free its resources (lower the clock, free some memory, etc.) Let's add an optional phandle to our firmware node.
