[PATCH v1 1/3] dt-bindings: connector: Add SPR AVS Sink APDO definitions

[Badhri Jagan Sridharan]

USB Power Delivery 3.2 introduces a new power supply type SPR AVS.
Add macro definitions for the USB Power Delivery (PD)
Standard Power Range (SPR) Adjustable Voltage Supply (AVS) as a
Sink Augmented Power Data Object (APDO) in the device tree bindings.
