Merge tag 'char-misc-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc and other driver subsystem updates from Greg KH:
 "Here is the large set of driver changes for char/misc drivers and
  other smaller driver subsystems that flow through this git tree.

  Included in here are:

   - New IIO drivers and features and improvments in that subsystem

   - New hwtracing drivers and additions to that subsystem

   - lots of interconnect changes and new drivers as that subsystem
     seems under very active development recently. This required also
     merging in the icc subsystem changes through this tree.

   - FPGA driver updates

   - counter subsystem and driver updates

   - MHI driver updates

   - nvmem driver updates

   - documentation updates

   - Other smaller driver updates and fixes, full details in the
     shortlog

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