[PATCH v3 0/9] usb: typec: Driver for Intel PMC Mux-Agent

[Heikki Krogerus]

Hi,

The statements were ended incorrectly with comma instead of semicolon
in drivers/usb/cdns3/core.c (PATCH 5/9) as pointed out by Peter. I've
fixed that in this version. There are no other changes.

v2 commit message:

I've unified the driver data handling in all drivers in patch 5/9 as
requested by Peter, and also now using consistently dev_set_drvdata()
in patch 4/9 as requested by Chunfeng Yun. Those were the only
changes in this version.

The original (v1) commit message:

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,
