Merge tag 'char-misc-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc drivers updates from Greg KH:
 "Here is the "big" set of char/misc and other driver subsystems for
  6.4-rc1.

  It's pretty big, but due to the removal of pcmcia drivers, almost
  breaks even for number of lines added vs. removed, a nice change.

  Included in here are:

   - removal of unused PCMCIA drivers (finally!)

   - Interconnect driver updates and additions

   - Lots of IIO driver updates and additions

   - MHI driver updates

   - Coresight driver updates

   - NVMEM driver updates, which required some OF updates

   - W1 driver updates and a new maintainer to manage the subsystem

   - FPGA driver updates

   - New driver subsystem, CDX, for AMD systems

   - lots of other small driver updates and additions

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