Subject: Question about nct6775 regarding MFD

Hi folks,

we are currently refactoring some parts of the 
"drivers/platform/x86/siemens/*" which has references to some

Nuvoton Super-I/O chips. One of them is the nct6775.

The driver in question is not implemented as MFD, even though MFD would 
have fit perfectly for it (or am I wrong?).

My question now:

Why wasn't the driver implemented as an MFD? Was MFD discussed during 
your upstreaming-related conversations?

Kind regards,

Benedikt
