Hi John
I try to use atomic_check with crtc_state, but it seems not easy,
there are two value need transmit from connector to vop: connector type
and out_mode
the connector type I think we can loop the atomic state to find the
connector type.
but the out_mode is a custom value, I can't find a generic way to
transmit it with atomic state.
BTW, I think on atomic side, the drm_display_mode is under control by
atomic state,
and the mode->private_flags is not use by drm framework, I found i915
and gma500 also use
mode->private_flags to transmit custom value.
So I think it's no problem using mode->private_flags.
