Merge tag 'char-misc-4.21-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 and misc driver patches for 4.21-rc1.

  Lots of different types of driver things in here, as this tree seems
  to be the "collection of various driver subsystems not big enough to
  have their own git tree" lately.

  Anyway, some highlights of the changes in here:

   - binderfs: is it a rule that all driver subsystems will eventually
     grow to have their own filesystem? Binder now has one to handle the
     use of it in containerized systems.

     This was discussed at the Plumbers conference a few months ago and
     knocked into mergable shape very fast by Christian Brauner. Who
     also has signed up to be another binder maintainer, showing a
     distinct lack of good judgement :)

   - binder updates and fixes

   - mei driver updates

   - fpga driver updates and additions

   - thunderbolt driver updates

   - soundwire driver updates

   - extcon driver updates

   - nvmem driver updates

   - hyper-v driver updates

   - coresight driver updates

   - pvpanic driver additions and reworking for more device support

   - lp driver updates. Yes really, it's _finally_ moved to the proper
     parallal port driver model, something I never thought I would see
     happen. Good stuff.

   - other tiny driver updates and fixes.

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