Subject: [PATCH v2] dt-bindings: eeprom/at24: Add samsung, s524ad0xd1 compatible
Date: Tue, 26 Apr 2022 12:59:39 -0500 [thread overview]
Message-ID: <20220426175938.2262966-1-robh@kernel.org> (raw)
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.
Signed-off-by: Rob Herring <robh@kernel.org>

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