Merge tag 'staging-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO updates from Greg KH:
 "Here is the big staging/iio driver patches for 5.6-rc1

  Included in here are:

   - lots of new IIO drivers and updates for that subsystem

   - the usual huge quantity of minor cleanups for staging drivers

   - removal of the following staging drivers:
       - isdn/avm
       - isdn/gigaset
       - isdn/hysdn
       - octeon-usb
       - octeon ethernet

  Overall we deleted far more lines than we added, removing over 40k of
  old and obsolete driver code.

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