[PATCH v3 06/14] drm/rockchip: vop2: Set YUV/RGB overlay mode

Andy Yan
2023-11-30T12:24:15Z

Set overlay mode register according to the
output mode is yuv or rgb.

Signed-off-by: Andy Yan <andy.yan@rock-chips.com>

Changes in v3:
- put bool variable yuv_overlay next to other bool variable
- define macro for RK3568_OVL_CTRL__YUV_MODE
- just write RK3568_OVL_CTRL register once in function
vop2_setup_layer_mixer
