[PATCH v1 2/3] power: supply: Add PD SPR AVS support to USB type enum
From: Badhri Jagan Sridharan
Date: Thu Feb 26 2026 - 00:55:01 EST
Add two new members to the power_supply_usb_type to represent the
USB Power Delivery (PD) Standard Power Range (SPR) Adjustable Voltage
Supply (AVS) charging types:
POWER_SUPPLY_USB_TYPE_PD_SPR_AVS: For devices supporting only the
PD SPR AVS type.
POWER_SUPPLY_USB_TYPE_PD_PPS_SPR_AVS: For devices that support both
PD Programmable Power Supply (PPS) and PD SPR AVS.
