Subject: [PULL REQUEST] i2c for v5.6

Linus,

here is my pull request for this cycle. I finally started using
'--edit-description' of 'git branch', so hopefully this is helpful to
you. Other than that, my pull request and some of the applied patches
are later than I would like, yet the christmas and holiday season were
shortening the working time of this cycle quite a bit. Still, all the
code got linux-next coverage and didn't show conflicts.

Please pull.

Thanks,

   Wolfram

  i2c: cros-ec-tunnel: Fix ACPI identifier (2020-01-31 09:01:25 +0100)

----------------------------------------------------------------
(from the branch description for i2c/for-5.6 local branch)

The I2C subsystems has for 5.6:

- huge improvements and refactorizations of the Linux I2C documentation
  (lots of thanks to Luca for doing it and Jean for the careful review)
- subsystem wide API conversion to i2c_new_client_device()
- remove obsolete parport-light driver
- smaller core updates (removal of 'extern', enabling more compile testing,
  use more helper macros)
- and quite a bunch of driver updates (new IDs, simplifications, better PM,
  support of atomic transfers and other improvements)

i2c-mux updates for 5.6:

- The main feature is the idle-state rework of the pca954x driver from
  Biwen Li

at24 updates for 5.6:

- minor maintenance: update the license tag, sort headers
- move support for the write-protect pin into nvmem core
- add a reference to the new wp-gpios property in nvmem to at25 bindings
- add support for regulator and pm_runtime control
