[PATCH V4 0/2] nvmem: add and use generic MMIO NVMEM

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

MMIO accessible NVMEM devices should be simple enough to allow using a
single binding & driver for them.

In V3 I didn't decide to modify existing Mediatek & UniPhier drivers as
there are some concerns about adding writing support to them. If needed
that can be done later.

Once we get layouts support NVRAM driver will get migrated into one and
generic MMIO driver will take over its binding.
