From d4949bf9cc6696c551b0b7b7111372cc8d2a35a9 Mon Sep 17 00:00:00 2001 From: Chukun Pan Date: Sun, 10 Oct 2021 21:50:17 +0800 Subject: arm64: dts: allwinner: NanoPi R1S H5: Add generic compatible string for I2C EEPROM The 'microchip,24c02' compatible does not match the at24 driver, so add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table. Also set this eeprom to read-only mode because it stores the mac address of the onboard usb network card.
