From c1e98dfad80bdb512cd04c9ed5d989a5f0f6b13d Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 9 Apr 2021 17:16:42 +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.
