Cory and Han,

MTD partitions may have been created from a DT definition, and in this case
the ->of_node of the struct device embedded in mtd_info should point to
the DT node that was used to create the partition.

Applied to l2-mtd.git/next (for 4.5). This will show up in
linux-next.git after the merge window.

Hi Vignesh,
Sorry for the late review. I did not have time to review much back when
you submitted your first RFCs for this.

That seems like a pretty good idea to me.

The lock flag of ofpart is undocumented. Add to binding doc.

It seems my reasoning here [1] was wrong (thanks Sascha!). This is a rewrite of
Michal's binding doc from [2].
Note that
t have to drop the upper 8 bits. That's
what these two commits did for read ID and parameter page read commands:

Hi Bayi,
In reviewing your updated instructions on how to read 6 bytes of ID, I
have one more question about how the PRGDATA and SHREG registers are
supposed to work.

Hi Bayi,
(I drafted most of this before you clarified on how to read out 6 bytes
of ID. So a bit of this is slightly out-of-date. Still, I think most of
the comments and much of the appended patch should be useful to you.)

To avoid conflict with other drivers using subnodes of the mtd device
create only one ofpart-specific node rather than any number of
arbitrary partition subnodes.
