I add the new, required property "nuvoton,sys-mgr" in the file
nuvoton-common-npcm7xx.dtsi.
The file nuvoton-common-npcm7xx.dtsi is required by the existing
upstream NPCM devicetree files.
It is also updated and committed in this patch set [PATCH v2 01/11]
arm: dts: add new property for NPCM i2c module.
Please let me know if I misunderstand the meaning of "breaking the ABI".
Thank you again.
