Currently, PMICs such as the PM8150B have an integrated type C block, which can be utilized for this. This series adds the dt-binding, PMIC type C driver, and DTS nodes. The PMIC type C driver will register itself as a type C port w/ a registered type C switch for orientation, and will fetch a USB role switch handle for the role notifications. It will also have the ability to enable the VBUS output to any connected devices based on if the device is behaving as a UFP or DFP.
