Pull char/misc and other driver updates from Greg KH:
 "Here is the big set of char/misc and other small driver subsystem
  updates for 5.18-rc1.

  Included in here are merges from driver subsystems which contain:

   - iio driver updates and new drivers

   - fsi driver updates

   - fpga driver updates

   - habanalabs driver updates and support for new hardware

   - soundwire driver updates and new drivers

   - phy driver updates and new drivers

   - coresight driver updates

   - icc driver updates

  Individual changes include:

   - mei driver updates

   - interconnect driver updates

   - new PECI driver subsystem added

   - vmci driver updates

   - lots of tiny misc/char driver updates

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

This framework aims at solve these problems. It also introduces DT
representation for consumer devices to go get the data they require (MAC
Addresses, SoC/Revision ID, part numbers, and so on) from the NVMEMs. This
framework is based on regmap, so that most of the abstraction available in
regmap can be reused, across multiple types of buses.
