5133 * @port: The port to check. A leaf of the MST tree with an attached display.
5134 *
5135 * Depending on the situation, DSC may be enabled via the endpoint aux,
5136 * the immediately upstream aux, or the connector's physical aux.

5138 * This is both the correct aux to read DSC_CAPABILITY and the
