The VOP in Rockchip SoCs that support YUV planes also support swapping of the U and V elements. Supporting the swapped variants, especially NV21, would be beneficial for multimedia applications, as the hardware video decoders only output NV21, and supporting this pixel format in the display pipeline would allow the decoded video frames to be output directly. Add support for this to support the various formats that have U/V swapped. Signed-off-by: Chen-Yu Tsai <wenst@chromium.org> --- This was tested on an ROC-RK3399-PC with modetest only. Changes to all other SoC platforms were based on their respective TRMs. --- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 20 +++++++++++++++++++- drivers/gpu/drm/rockchip/rockchip_drm_vop.h | 1 + drivers/gpu/drm/rockchip/rockchip_vop_reg.c | 11 +++++++++++ 3 files changed, 31 insertions(+), 1 deletion(-)
