[PATCH v2 1/3] dt-bindings: display: bridge: simple: Add data-enable-active to dumb-vga-dac

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@xxxxxxxxxxx>

Some simple VGA DACs may include a data-enable input that must be driven
at a specific polarity. Add the data-enable-active property from
video-interfaces to the input endpoint to describe that polarity.
