Current description of the compatible property for at24 is quite vague.
Specify an exact list of accepted compatibles and document the - now

Why is it suddenly deprecated to correctly specify what hardware you
have, e.g. "nxp,24c32". In this case the manufacturer is nxp, damnit.
Sure, it happens to be compatible with "atmel,24c32", but that is
supposed to be written with a fallback as
"nxp,24c32", "atmel,24c32"
if I understand correctly. So, why is that deprecated in this case?
What if (a few years down the line) it is discovered that some weird
quirk is needed that is only appropriate for nxp chips?
nxp is of course just an example, pick any manufacturer of eeproms
(supposedly) compatible with the atmel interface.
So now I am supposed to change my device tree from "microchip,24c128" to
"atmel,24c128"?
Also, at,24c08 is listed in
Documentation/devicetree/bindings/trivial-devices.txt. It should
probably be removed.
