Merge tag 'char-misc-5.3-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 "large" pull request for char and misc and other assorted
  smaller driver subsystems for 5.3-rc1.

  It seems that this tree is becoming the funnel point of lots of
  smaller driver subsystems, which is fine for me, but that's why it is
  getting larger over time and does not just contain stuff under
  drivers/char/ and drivers/misc.

  Lots of small updates all over the place here from different driver
  subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates
   - w1 driver fixes

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