Subject: [PATCH 5.8 42/99] drm/sun4i: sun8i-csc: Secondary CSC register correction

From: Martin Cerveny <m.cerveny@...puter.org>

[ Upstream commit cab4c03b4ba54c8d9378298cacb8bc0fd74ceece ]

"Allwinner V3s" has secondary video layer (VI).
Decoded video is displayed in wrong colors until
secondary CSC registers are programmed correctly.
