From 77b0e8ded57e7fb5d742fb533d7a9bb3f3788513 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 13 Jan 2021 11:20:08 +0100 Subject: [PATCH] drm/vc4: hdmi: Replace CSC_CTL hardcoded value by defines On BCM2711, the HDMI_CSC_CTL register value has been hardcoded to an opaque value. Let's replace it with properly defined values.
