Subject: [PATCH] arm64: dts: allwinner: NanoPi R1S H5: use the correct compatible for the eeprom
Date:   Fri,  1 Oct 2021 22:50:36 +0800
Message-Id: <20211001145036.18129-1-amadeus@jmu.edu.cn>
Precedence: bulk

The 'microchip,24c02' compatible does not match the at24 driver, so
replace it with 'atmel,24c02'. In addition, because the mac address
is stored on this eeprom, set it to read-only mode.
