Merge tag 'char-misc-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Browse Source 
Pull char/misc drivers updates from Greg KH:
 "Here is the "big" set of char/misc and other driver subsystems for
  6.4-rc1.

  It's pretty big, but due to the removal of pcmcia drivers, almost
  breaks even for number of lines added vs. removed, a nice change.

  Included in here are:

   - removal of unused PCMCIA drivers (finally!)

   - Interconnect driver updates and additions

   - Lots of IIO driver updates and additions

   - MHI driver updates

   - Coresight driver updates

   - NVMEM driver updates, which required some OF updates

   - W1 driver updates and a new maintainer to manage the subsystem

   - FPGA driver updates

   - New driver subsystem, CDX, for AMD systems

   - lots of other small driver updates and additions

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

8. NVMEM layouts
================
NVMEM layouts are yet another mechanism to create cells. With the device
tree binding it is possible to specify simple cells by using an offset
and a length. Sometimes, the cells doesn't have a static offset, but
the content is still well defined, e.g. tag-length-values. In this case,
the NVMEM device content has to be first parsed and the cells need to
be added accordingly. Layouts let you read the content of the NVMEM device
and let you add cells dynamically.
Another use case for layouts is the post processing of cells. With layouts,
it is possible to associate a custom post processing hook to a cell. It
even possible to add this hook to cells not created by the layout itself.
