[PATCH 06/10] arm64: dts: ti: k3-am642-evm: Enable main_i2c0 and eeprom

From: Nishanth Menon
Date: Fri Apr 14 2023 - 03:34:00 EST


Enable AT24CM01 on the base board using the corresponding compatible.

Note:
checkpatch does a simple pattern search and fails to find a match
#47: FILE: arch/arm64/boot/dts/ti/k3-am642-evm.dts:353:
compatible = "atmel,24c1024";

But, Documentation/devicetree/bindings/eeprom/at24.yaml
- items:
pattern: cs1024$
Cleanly covers the same and dtbs_check looks clean.
