[PATCH 0/4] use correct compatibles for the nxp,se97b chips

[Peter Rosin]

Hi!

The TSE-850 and the Nattis are using se97b chips from NXP. Previously,
these have been specified as compatible to "nxp,24c02". But the updated
bindings for the at24 eeproms makes me think that the right thing to
do is to have their compatible be

   "nxp,se97b", "atmel,24c02"

This series takes care of that, and throws in a sorting patch while at it.

Cheers,
Peter

The datasheet talks about the chip being an spd, but the chip is writable
so atmel,24c02 is more appropriate as fallback.

[Peter Rosin]

The used part does contain an eeprom compatible with an Atmel 24c02
chip and it is from NXP, but it is not called 24c02. It's actually a
se97b chip. Adjust the compatible accordingly.

This one should go into 4.16. I can apply after rc1 or apply to tree 
with at24.txt changes queued.

Wolfram,

can you take this via the i2c tree for 4.16?

I missed this mail because I leave at24 patches to you now.
Please send pull requests for patches I shall take. Least room for
confusion (I hope).

Will do. What about this (http://patchwork.ozlabs.org/patch/867169/)
one? It's part of a bigger series, do you want me to apply it to my

Well, I would accept it for 4.16 using the "plain new id" rule. So, if
you add it on top of Peter's sorting patch, totally fine by me.

If you want it in v4.17, ok, too. I'd think an immutable branch is not
needed. There is a fallback property in the DTS. So at worst, there will
be a DTS warning during the merge window which will be fixed at rc1 time.

Unless I overlooked something.
