Merge tag 'usb-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of Thunderbolt and USB changes for 6.0-rc1.

  Lots of little things here, nothing major, just constant development
  on some new hardware support and cleanups of older drivers. Highlights
  are:

   - lots of typec changes and improvements for new hardware

   - new gadget controller driver

   - thunderbolt support for new hardware

   - the normal set of new usb-serial device ids and cleanups

   - loads of dwc3 controller fixes and improvements

   - mtu3 driver updates

   - testusb fixes for longtime issues (not many people use this tool it
     seems.)

   - minor driver fixes and improvements over the USB tree

   - chromeos platform driver changes were added and then reverted as
     they depened on some typec changes, but the cross-tree merges
     caused problems so they will come back later through the platform
     tree.

  All of these have been in linux-next for a while now with no reported
  issues"

Description:

		set of Power Data Objects (PDO), each representing a type of

		power supply. The order of the PDO objects is defined in the USB

		Power Delivery Specification. Each PDO - power supply - will

		have its own device, and the PDO device name will start with the

		object position number as the first character followed by the

		power supply type name (":" as delimiter).

Description:

		The sink capability message "Sink_Capabilities" contains a set

		of Power Data Objects (PDO) just like with source capabilities,

		describe the power requirements.



		The order of the objects in the sink capability message is the

		same as with the source capabilities message.



Fixed Supplies

Description:

		Devices containing the attributes (the bit fields) defined for

		Fixed Supplies.



		The device "1:fixed_supply" is special. USB Power Delivery

		Specification dictates that the first PDO (at object position

		1), and the only mandatory PDO, is always the vSafe5V Fixed

		Supply Object. vSafe5V Object has additional fields defined for

		it that the other Fixed Supply Objects do not have and that are

		related to the USB capabilities rather than power capabilities.
