From 12795909c4956c70c1d3a1517c620b27d51974ea Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 23 Jun 2021 11:48:35 +0200 Subject: [PATCH 424/828] 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.
