This should probably go in 1/4 patch. Other than that series looks good to me.

FYI patch 1/4 is also carried by the nvmem-layouts series, so it's
probably best to keep these 2 patches separated to simplify the merging.
that is intermediate thing, but Ideally this change belongs to 1/4 patch, so once I apply these patches then we can always rebase layout series on top of nvmem-next

Well, I still don't see the need for this patch because we have no use
for it *after* the introduction of layouts. Yes in some cases changing
the size of a cell might maybe be needed, but right now the use case is
to provide a MAC address, we know beforehand the size of the cell, so
there is no need, currently, for this hack.

Am confused, should I ignore this series ?

Whatever. If you want it, just merge it. But *please*, I would like

:-)

to see these layouts in, so what's the plan?

Am on it, you sent v3 just 24hrs ago :-)
