Subject: [PATCH 0/3] Introduce PMIC based USB type C detection

Add the required drivers for implementing type C orientation and role
detection using the Qualcomm PMIC.  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.
