Merge tag 'char-misc-6.10-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 big set of char/misc and other driver subsystem updates
  for 6.10-rc1. Nothing major here, just lots of new drivers and updates
  for apis and new hardware types. Included in here are:

   - big IIO driver updates with more devices and drivers added

   - fpga driver updates

   - hyper-v driver updates

   - uio_pruss driver removal, no one uses it, other drivers control the
     same hardware now

   - binder minor updates

   - mhi driver updates

   - excon driver updates

   - counter driver updates

   - accessability driver updates

   - coresight driver updates

   - other hwtracing driver updates

   - nvmem driver updates

   - slimbus driver updates

   - spmi driver updates

   - other smaller misc and char driver updates

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