[PATCH v2] dt-bindings: eeprom/at24: Add samsung,s524ad0xd1 compatible

From: Rob Herring
Date: Tue Apr 26 2022 - 14:00:24 EST


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.
