Merge tag 'char-misc-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc driver updates from Greg KH:
 "Here is the "big" set of char/misc and other driver subsystem changes
  for 6.12-rc1.

  Lots of changes in here, primarily dominated by the usual IIO driver
  updates and additions, but there are also small driver subsystem
  updates all over the place. Included in here are:

   - lots and lots of new IIO drivers and updates to existing ones

   - interconnect subsystem updates and new drivers

   - nvmem subsystem updates and new drivers

   - mhi driver updates

   - power supply subsystem updates

   - kobj_type const work for many different small subsystems

   - comedi driver fix

   - coresight subsystem and driver updates

   - fpga subsystem improvements

   - slimbus fixups

   - binder new feature addition for "frozen" notifications

   - lots and lots of other small driver updates and cleanups

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