Add support for stacked/parallel memories 
Merge series from Amit Kumar Mahapatra <amit.kumar-mahapatra@amd.com>:

This patch is in the continuation to the discussions which happened on
'commit f89504300e ("spi: Stacked/parallel memories bindings")' for
adding dt-binding support for stacked/parallel memories.

This patch series updated the spi-nor, spi core and the spi drivers
to add stacked and parallel memories support.

The first patch
https://lore.kernel.org/all/20230119185342.2093323-1-amit.kumar-mahapatra@amd.com/
of the previous series got applied to
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next
But the rest of the patches in the series did not get applied due to merge
conflict, so send the remaining patches in the series after rebasing it
on top of for-next branch.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
