From cab4c03b4ba54c8d9378298cacb8bc0fd74ceece Mon Sep 17 00:00:00 2001 From: Martin Cerveny Date: Sun, 6 Sep 2020 18:21:39 +0200 Subject: drm/sun4i: sun8i-csc: Secondary CSC register correction "Allwinner V3s" has secondary video layer (VI). Decoded video is displayed in wrong colors until secondary CSC registers are programmed correctly.
