Subject: [PATCH v3 0/2] drm/rockchip: vop: Add NV15, NV20 and NV30 support

This is a revival of a 3 year old series that never got picked up, see [1].

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 has been in use by LibreELEC and other distros for the
past 3+ years, hoping they can be merged this time around :-)

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 [2].
