Subject: [PATCH v6 00/14] TCPM support for FRS and AutoDischarge Disconnect

First of all apologies for mixing up the patch version as noted by
Heikki and Greg. All of them were v1's but since I was manually adding
the version numbers I mixed them up. Using the --reroll-count option
now. Updating the patch version to v6 (highest version number in the
previous patchset + 1) to avoid confusion.

I also rebased on to off of the recent usb-next tip:
5fedf0d295d3 (origin/usb-testing, origin/usb-next) Merge 5.9-rc3 into usb-next
Which had the following changes causing merge conflict:
3ed8e1c2ac99 usb: typec: tcpm: Migrate workqueue to RT priority for processing events
6bbe2a90a0bb usb: typec: tcpm: During PR_SWAP, source caps should be sent only after tSwapSourceStart

Addressed comments from Heikki and Randy which have described in the
individual commit's change history as well.
