This series 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 include 10-bit 4:4:4 support since VOP can support that also. First patch adds new fourcc 10-bit YUV formats with 4:2:2/4:4:4 sub-sampling. Second patch adds support for displaying the new fourcc formats. These patches have been in use by LibreELEC and other distros for the past 3+ years, hoping they can be merged this time around. A rough libdrm/modetest patch [2] have been used to validate use of NV15, NV20 and NV30 formats on RK3288, RK3328 and RK3399 boards. modetest -s <connector_id>@<crtc_id>:<mode>-<vrefresh>@<format> Tinker Board R2.0 (rk3288w): modetest -s 50:1920x1080-60@NV15 Rock Pi 4 (rk3399): modetest -s 52@44:1920x1080-60@NV15 Rock64 (rk3328): modetest -s 42:1920x1080-60@NV15 Changes in v5: - Use drm_format_info_min_pitch() for correct bpp - Add missing NV21, NV61 and NV42 formats Changes in v4: - Rework RK3328/RK3399 win0/1 data to not affect RK3368 Changes in v3: - No changes, rebased on next-20230616 - R-B tags was collected Changes in v2: - Add NV30 format - R-B tags was not collected due to NV30 changes This series is also available at [1] and libdrm/modetest patch at [2].
