So what? Does not seem incorrect to me. Maybe the description should
not be in MFD directory, but other than that...

You may want to learn more about device tree and/or talk to the device
tree maintainers. This is an old article.

NAK on this patch. I see that this binding has problems, but
introducing different binding for subset of devices is _not_ a fix.

I'd like to see common solutions for SFD and MFD, as the hardware is
similar, and that includes the code. Having code that is easier to
maintain is important, and having many drivers are harder to maintain
than one driver.

Milo's code looks better than yours in that regard. I disagree about
Milo's code being "nightmare" to modify, and care about "easy to
maintain" more than "binary size".

Best regards,
