From 3320e449e40eeb49b601dcbbd4bd72b8cb8f3054 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 14 Apr 2023 11:26:58 +0200 Subject: [PATCH] drm/vc4: tests: Add function to lookup a plane for a CRTC Some tests will need to find a plane to run a test on for a given CRTC. Let's create a small helper to do that.
