[PATCH] drm/rockchip: get rid of rockchip_drm_crtc_mode_config

Mark Yao
2016-04-18T03:03:31Z

We need to take care of the vop status when use
rockchip_drm_crtc_mode_config, if vop is disabled,
the function would failed, that is terrible.

Save connector type and output mode on drm_display_mode->private_flags
at encoder mode_fixup, then we can configure the type and mode safely
on crtc mode_set.
