| Maximum number of packet retransmissions done by TCPC. Valid values are <0, 3>. |
| This value is used to fill the Retry Counter part of the TCPCI Transmit register. |

| GPIO pin for VCONN control. RT1715 does not have built-in VCONN power supply. If the |
| state of the VCONN power supply need to be toggled, this pin and a switchable power |
| supply are required. |

| type: phandle-array |
| description: | |
| GPIO pin for VCONN discharge control. RT1715 does not have VCONN discharge capability. |
| If VCONN discharge is not needed, this pin does not need to be defined in the device |
| tree. Otherwise, this pin and a discharge path are required. |
