[PATCH v2 2/2] drm: rockchip: add NV15, NV20 and NV30 support

From: Jonas Karlman
Date: Mon Jul 06 2020 - 18:30:21 EST


Add support for displaying 10-bit 4:2:0 and 4:2:2 formats produced by the
Rockchip Video Decoder on RK322X, RK3288, RK3328, RK3368 and RK3399.
Also add support for 10-bit 4:4:4 format while at it.

V2: Added NV30 support
