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.
