Merge tag 'staging-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO driver updates from Greg KH:
 "Here is the "big" set of staging and IIO driver patches for 5.12-rc1.

  Nothing really huge in here, the number of staging tree patches has
  gone down for a bit, maybe there's only so much churn to happen in
  here at the moment.

  The IIO changes are:

   - new drivers

   - new DT bindings

   - new iio driver features

  with full details in the shortlog.

  The staging driver patches are just a lot of tiny coding style
  cleanups, along with some semi-larger hikey driver cleanups as those
  are _almost_ good enough to get out of the staging tree, but will
  probably have to wait until 5.13 to have happen.

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