[PATCH v2 0/3] usb: typec: add Rohm BM92TXX Type-C / PD controller driver
From: Alexandre Hamamdjian via B4 Relay
Date: Sun May 10 2026 - 14:34:56 EST
This series adds initial support for the Rohm Semiconductor BM92TXX
family of USB Type-C and Power Delivery controllers.
This chipset is found on Nintendo Switch hardware, where it handles
charger and dock USB-C / PD negotiation, DisplayPort alternate-mode
entry through the dock and VBUS / VCONN control.
Further patches will follow to wire the driver up on Nintendo Switch
device trees and to address review feedback.
