I found only one user for "atmel,at25" in any of the DT sample files.
arch/arm/boot/dts/phy3250.dts:
eeprom: at25@0 {
...
at25,byte-len = <0x8000>;
at25,addr-mode = <2>;
at25,page-size = <64>;
compatible = "atmel,at25";
reg = <0>;
spi-max-frequency = <5000000>;
};
I think np->name is "at25" in this case? The binding file
Documentation/devicetree/bindings/misc/at25.txt also has the same name.
Are you OK, if we add something like below to the changelog?
In addition we hard-code the name of the chip to be "at25" for the
reason that there is no common mechanism to fetch name of the firmware
node. The only existing user (arch/arm/boot/dts/phy3250.dts) uses the
same name so it should continue to work.
