It is perhaps obvious that I think the patch should be merged (as I 
wrote it and sent it to you).  However, I think there is a bit of 
process problem here.  Patches that affect device tree bindings are part 
of the de facto kernel ABI, and as such, need proper vetting.  It is my 
opinion that neither the original patch, nor this one correcting it, 
should have been committed without either Grant or Rob giving an Acked-by.

to my char-misc git tree which can be found at
     git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-next branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release
during the merge window.

If you have any questions about this process, please let me know.

Subject: misc/at25, dt: Improve at25 SPI eeprom device tree bindings.

Commit 002176db (misc: at25: Parse dt settings) added device tree
bindings the differ significantly in style from the I2C EEPROM
bindings and don't seem well vetted.  Here I deprecate (but still
support) the "at25,*" properties, and add what I hope is a better
alternative.  These new bindings also happen to be deployed in the
field and were previously submitted for consideration here:

https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html

The advantages of the new bindings are that they are similar to the
I2C EEPROMs and they don't conflate read-only and the address width
modes in a binary encoded blob.
