Merge tag 'char-misc-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc / other smaller driver subsystem updates from Greg KH:
 "Here is the large set of char, misc, and other driver subsystem
  updates for 5.19-rc1. The merge request for this has been delayed as I
  wanted to get lots of linux-next testing due to some late arrivals of
  changes for the habannalabs driver.

  Highlights of this merge are:

   - habanalabs driver updates for new hardware types and fixes and
     other updates

   - IIO driver tree merge which includes loads of new IIO drivers and
     cleanups and additions

   - PHY driver tree merge with new drivers and small updates to
     existing ones

   - interconnect driver tree merge with fixes and updates

   - soundwire driver tree merge with some small fixes

   - coresight driver tree merge with small fixes and updates

   - mhi bus driver tree merge with lots of updates and new device
     support

   - firmware driver updates

   - fpga driver updates

   - lkdtm driver updates (with a merge conflict, more on that below)

   - extcon driver tree merge with small updates

   - lots of other tiny driver updates and fixes and cleanups, full
     details in the shortlog.

  All of these have been in linux-next for almost 2 weeks with no
  reported problems"
