From 87acf1cdb2f032f79db742cbd16a65ee7b9543e2 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 23 Jun 2021 11:48:35 +0200 Subject: [PATCH 436/634] 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.
