From 76a262d274a2f23ac0fee24ff3e4d1a8276b95e2 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 30 Apr 2021 11:44:51 +0200 Subject: [PATCH] drm/vc4: hdmi: Signal the proper colorimetry info in the infoframe Our driver while supporting HDR didn't send the proper colorimetry info in the AVI infoframe. Let's add the property needed so that the userspace can let us know what the colorspace is supposed to be.
