No such thing as an MFD device, what is it? PMIC, no?

Abbreviation is PMIC, please reflect that here.

As above.
No need to line break here.

GPIO

Why Kerneldoc for static functions.

No thank you.
And for all the other useless dev_dbg() prints that in this file which
no one is going to use.

Would all of the above be better off in drivers/power?

One device, which isn't even a device, is not an MFD.
Where are the other devices?
They need to be added now, rather than later please.

This usually goes at the bottom of the file.

Normally placed at the bottom of the list.

No line break on the 2nd line.

No __func__

Why not propagate 'ret'?

This will probably go onto one line (<100 chars)

if (!sys_power_controller)

Is that really what you want?
What about the other driver that thinks it's the
system-power-controller? Seems wrong.
In any case, make this line as short / succinct as you can.

Do you use this param?
If not drop the whole table and use .probe_new.
