Consider if they are expected or the schema is incorrect. These may not be new warnings. Note that it is not yet a requirement to have 0 warnings for dtbs_check. This will change in the future.

DP_INTF is similar to DPI but does not have the exact same feature set or register layouts. DP_INTF is the sink of the display pipeline that is connected to the DisplayPort controller and encoder unit. It takes the same clocks as DPI.
