This patch is in the continuation to the discussions which happened on
'commit f89504300e94 ("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.
