Handling (creating) partitions for flash devices requires using a proper
driver that will read partition table (out of somewhere). We can't
simply try all existing drivers one by one, so MTD subsystem allows
drivers to specify a list of applicable part probes.
So far physmap_of was the only driver with support for linux,part-probe
DT property. Other ones had list or probes hardcoded which wasn't making
them really flexible. It prevented using common flash drivers on
platforms that required some specific partition table access.
This commit moves support for mentioned DT property to the MTD core
file. Thanks to calling it on device parse registration (as suggested by
Boris) all drivers gain support for it for free.

Maybe you should split the patch:
1/ add core infrastructure
2/ remove open-coded version in drivers/mtd/maps/physmap_of.c
What's the gain of that? Is this patch too complex to review properly? Will that
be useful for anyone to have it split? For me it only adds an intermediate code
duplication.
BTW, not sure the intermediate "mtd: physmap_of: use OF helpers
for reading strings" patch is really useful, since you move to the
common infrastructure here.
By following my suggestion you get rid of the dependency you have
between this series and patch "mtd: physmap_of: use OF helpers for
reading strings".
I learned (the very hard way) MTD people can be really nitpicking so I'm
sending as simple patches as I can. I see it as the only way for someone from
OpenWrt/LEDE project to get patch through your review.
It's like with this patch: even a simple code move can be questioned. Please
drop this patchset, I'll resend it after/if I manage to get
[PATCH] mtd: physmap_of: use OF helpers for reading strings
accepted.
