[v3,00/20,v3,00/20] nvmem: Layouts support

  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

A linux-0day branch for kernel test robot has been pushed to get wider
testing.

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. There is an
immutable tag on the mtd repository available:

----------------------------------------------------------------
The following changes since commit fe15c26ee26efa11741a7b632e9f23b01aca4cc6:

  Linux 6.3-rc1 (2023-03-05 14:52:03 -0800)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git tags/mtd/core-fixes-before-nvmem-layouts-for-6.4

for you to fetch changes up to 281f7a6c1a33fffcde32001bacbb4f672140fbf9:

  mtd: core: prepare mtd_otp_nvmem_add() to handle -EPROBE_DEFER (2023-03-08 14:31:49 +0100)
----------------------------------------------------------------

So to summarize:
* Rob's feedback is welcome on the remaining un-acked OF patche
* 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
  above with Michael's patches before taking this series in.

Thanks,
Miquèl

Changes in v3:
* Rebased on top of nvmem-next and handled a few conflicts.
* Minor changes in the OF commit logs.
* Fixed a missing header reported by kernel test robot.
* Mention immutable tag.
* Collected more tags.
* Fix of/module.c license.

Changes in v2:
* Included all initial core nvmem changes.
* Merged all the relevant fixes.
* Updated the commit logs of the Fixes tag when relevant.
* Followed Rob advises to migrate the module related helpers into
  of/module.c and get the useless helpers out of of_device.c
* Added my Signed-off-by when relevant.
* Collected tags.
