Pull char/misc driver updates from Greg KH:
 "Here is the big set of char/misc and other small driver subsystem
  changes for 6.6-rc1.

  Stuff all over the place here, lots of driver updates and changes and
  new additions. Short summary is:

   - new IIO drivers and updates

   - Interconnect driver updates

   - fpga driver updates and additions

   - fsi driver updates

   - mei driver updates

   - coresight driver updates

   - nvmem driver updates

   - counter driver updates

   - lots of smaller misc and char driver updates and additions

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