Merge tag 'char-misc-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc and other driver updates from Greg KH:
 "Here is the large set of char/misc and other small driver subsystem
  changes for 6.1-rc1. Loads of different things in here:

   - IIO driver updates, additions, and changes. Probably the largest
     part of the diffstat

   - habanalabs driver update with support for new hardware and
     features, the second largest part of the diff.

   - fpga subsystem driver updates and additions

   - mhi subsystem updates

   - Coresight driver updates

   - gnss subsystem updates

   - extcon driver updates

   - icc subsystem updates

   - fsi subsystem updates

   - nvmem subsystem and driver updates

   - misc driver updates

   - speakup driver additions for new features

   - lots of tiny driver updates and cleanups

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