Hi,

This series adds 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.

First patch adds a new fourcc 10-bit YUV format with 4:2:2 sub-sampling.
Second patch adds support for using the the two new fourcc formats.
Both depend on "drm: drm_fourcc: add NV15, Q410, Q401 YUV formats" at [1].

This series can also be found at [2], and can be tested on RK3399 using an
upcoming rkvdec series at [3] together with ffmpeg at [4] and kodi-gbm or mpv.
