Subject: [PATCH v10 01/21] dt-bindings: mediatek,dpi: Add DPINTF compatible

From: Markus Schneider-Pargmann <msp@...libre.com>

DPINTF is similar to DPI but does not have the exact same feature set
or register layouts.

DPINTF is the sink of the display pipeline that is connected to the
DisplayPort controller and encoder unit. It takes the same clocks as
DPI.
