Subject: [PATCH v2 0/4] usb: typec: WUSB3801 devicetree bindings and driver
Date: Wed, 2 Feb 2022 16:19:43 -0600 [thread overview]
Message-ID: <20220202221948.5690-1-samuel@sholland.org> (raw)
This series adds bindings and a driver for the Willsemi WUSB3801. This
chip's bindings use the standard USB Type-C connector bindings, but the
driver does not use the TCPM library, so a refactoring patch is included
to avoid duplicating some fwnode parsing code.
Changes in v2:
- Always put the return values from typec_find_* in a signed variable
for error checking.
- License the driver as GPL 2 only; probably best anyway as I used a
lot of other drivers/usb/typec code as inspiration
- Don't try to be clever; use `default` instead of `unreachable`
- Free the IRQ before unregistering the partner/port
Samuel Holland (4):
dt-bindings: vendor-prefixes: Add willsemi
dt-bindings: usb: Add WUSB3801 Type-C Port Controller
usb: typec: Factor out non-PD fwnode properties
usb: typec: Support the WUSB3801 port controller
