13  A USB connector node represents a physical USB connector. It should be a child
14  of a USB interface controller or a separate node when it is attached to both
15  MUX and USB interface controller.

199      different power levels and "6.4.1.3.1.6 Fast Role Swap USB Type-C Current"
200      provides a detailed description of the field. The sink PDO from current source
201      reflects the current source's(i.e. transmitter of the FRS signal) power
202      requirement during fr swap. The current sink (i.e. receiver of the FRS signal),
203      a.k.a new source, should check if it will be able to satisfy the current source's,
204      new sink's, requirement during frswap before enabling the frs signal reception.
205      This property refers to maximum current capability that the current sink can
206      satisfy. During FRS, VBUS voltage is at 5V, as the partners are in implicit
207      contract, hence, the power level is only a function of the current capability.
208      "1" refers to default USB power level as described by "Table 6-14 Fixed Supply PDO - Sink".
209      "2" refers to 1.5A@5V.
