[PATCH v5 2/2] drm/rockchip: vop: Add NV15, NV20 and NV30 support

From: Jonas Karlman
Date: Mon Oct 23 2023 - 13:47:47 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 and RK3399.
Also add support for 10-bit 4:4:4 format while at it.

V5: Use drm_format_info_min_pitch() for correct bpp
Add missing NV21, NV61 and NV42 formats
V4: Rework RK3328/RK3399 win0/1 data to not affect RK3368
V2: Added NV30 support
