The samsung,s524ad0xd1 compatible is in use, but not documented. According
to arch/arm/mach-s3c/mach-smdk6410.c, the samsung,s524ad0xd1 is compatible
with the 24c128. As the schema requires a fallback compatible to the
corresponding Atmel compatible, 'atmel,24c128' is added as a fallback.

v2:
 - Fix the example in samsung,s3c2410-i2c.yaml

There is still a DTS to fix. I assume you leave it for volunteers, so
I'll send a patch for it.


Best regards,
