[PATCH 0/9] usb: typec: Driver for Intel PMC Mux-Agent

Hi,

The Intel PMC (Power Management Controller) microcontroller, which is
available on most SOCs from Intel, has a function called mux-agent.
The mux-agent, when visible to the operating system, makes it possible
to control the various USB muxes on the system.

In practice the mux-agent is a device that controls multiple muxes.
Unfortunately both the USB Type-C Class and the USB Role Class don't
have proper support for that kind of devices that handle multiple
muxes, which is why I had to tweak the APIs a bit.

On top of the API changes, and the driver of course, I'm adding a
header for the Thunderbolt 3 alt mode since the "mux-agent" supports
it.

thanks,

Heikki Krogerus (9):
usb: typec: mux: Allow the muxes to be named
usb: typec: mux: Add helpers for setting the mux state
usb: typec: mux: Allow the mux handles to be requested with fwnode
usb: roles: Leave the private driver data pointer to the drivers
usb: roles: Provide the switch drivers handle to the switch in the API
usb: roles: Allow the role switches to be named
device property: Export fwnode_get_name()
usb: typec: Add definitions for Thunderbolt 3 Alternate Mode
