From: Mark Yao yzq@rock-chips.com
Add bpc and color mode setting in rockchip_drm_vop driver, so connector could try to use the edid drm_display_info to config vop output mode.
Signed-off-by: Mark Yao yzq@rock-chips.com Signed-off-by: Yakir Yang ykk@rock-chips.com --- Changes in v8: None Changes in v7: None Changes in v6: None Changes in v5: - Fix compiled error (Heiko) - Using the connector display info message to configure eDP driver input video mode, but hard code CRTC video output mode to RGBaaa.
Changes in v4: None Changes in v3: None Changes in v2: None
