[PATCH v2 00/21] nvmem: Layouts support

[Miquel Raynal <miquel.raynal@bootlin.com>]

Hello,

This is a fully featured series with hopefully all what is needed for
upstream acceptance, ie:
* A bit of OF cleanup
* Full nvmem layout support merging Michael's and my patches
* Only the fixes not applying to this series have been kept "un merged"
* Support for SL28 VPD and ONIE TLV table layouts
* Layouts can be compiled as modules

In order for this series to work out-of-the-box it requires to be
applied on top of Michael Walle's mtd fixes series (robots running on
it, I will provide an immutable tag in the coming days) but for
compile-testing only it is not required.

So to summarize:
* Rob's feedback is welcome on the OF patches
* Greg's and Srinivas feedback is welcome on the nvmem patches
* If everybody agrees I expect the full series to be applied rather
  early by Srinivas on top of the -rc he wants.
* Once time for the final PR I expect Greg to merge the immutable tag
  I will provide with Michael's patches before taking these patches from
  Srinivas.
* Rob might request an immutable tag from Greg (at least with the OF
  patches) if there are any conflicts with his tree. Otherwise if that's
  foreseen, Rob can also merge the OF patches and produce an immutable
  tag himself if that's preferred. Indeed, no hurry, but there are other
  OF cleanup patches which do not have to be in this series which will
  come later to continue the OF cleanup even further if my understanding
  of Rob's whishes is right :)
