[PATCH v3 0/4] usb: typec: WUSB3801 devicetree bindings and driver

[Samuel Holland]

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 v3:
 - Leave the call to fw_devlink_purge_absent_suppliers in its original
   place in the TCPM code. It is not needed by the new driver.
 - Remove unused variable from TCPM function.
 - Remove version info printout

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
