Re: [PATCH V9 0/4] mtd: read partitions compatible prop for "ofpart" type

This patchset provides a proper support for flash device DT node with
"partitions" subnode using "compatible" property. It's already
documented in the: Documentation/devicetree/bindings/mtd/partition.txt

We believed a previous version 8 was ready to go, but soon after landing
in the linux-next we got a regression report from Peter.

I retested these four patches on-top of 4.15, and results are good.

With a faulty partition layout in the dtb, the old command-line layout
wins and things keep working, and with a good partition layout in the
dtb I can remove a bunch of command-line clutter.

Tested-by: Peter Rosin <redacted>

No testing of the individual patches though, just the end result...

Cheers,

This version takes a safe path by:
1) Respecting parsers order as specified in the default/driver-provided
   list.
2) Looking at "compatible" property only when "ofpart" type gets
   speciied.

I double-checked the code and cannot think of any regression this could
cause. I also hope this design (roughly discussed with Boris) can be
acceptable for the mtd subsystem.

This is of course 4.17 material at best.
