And what is npcm for? Why it was made an directory?

All these should be just one Nuvoton.

npcm is an unrelated product line, so I think it would be best
to rename the npcm directory to nuvoton and move the new
file in there, though I'm not sure about the name or what the
other chips are called.

My impression is that this one is more closely related to
the older Arm9 nuc900/w90x900/n9 chips that we dropped from
the kernel a while ago, while the npcm family has a different
origin.

Dear Arnd and  Krzysztof,


Please allow me to answer the question of Krzysztof in this mail.

Thank you for your suggestion, then in the next version I will submit to 
rename directory npcm to nuvoton.

And rename this file nuvoton.yaml to nuvoton,ma35d1.yaml, and put in the 
nuvoton directory.

npcm focuses on the BMC field, and ma35 is the successor SoC of 
nuc970/nuc980,

which is mostly used in industrial control, consumer, network 
applications and other fields.

The two teams are located in different countries and regions, and there 
is little

communication and resource sharing with each other.
