Subject: Re: [PATCH v3 0/3] arm64: dts: nuvoton: add NPCM845 SoC and EVB support

Hi Rob,

Thanks for your comments

Most of the warnings occur because the compatible strings are located
in .txt device tree binding rather than in the .yaml file.

The only change that needs to be done is in ti,tmp100 that

Could you approve the patches, avoiding NPCM845 compatible warnings?
Meanwhile, I will work on converting the txt to yaml

Thanks,

Tomer
