This driver usese existing binding for exnos-chipid.
Nice!
Thanks for review.

I don't like the idea of having three extra nonstandard properties here,
especially when you are not using the machine field for anything useful.
I did not get you here. Any suggestions how we can use 'machine' field
more useful way.
Also, all three of these just come from the same register, why expose
them all as the machine and revision standard properties.
Agreed. These properties are basically giving same information but with
small modification.
As you said these are getting exposed via standard properties as well,
so I have no issue to drop them. Just waiting for more review from
Samsung folks, will take care of this in next version.
Thanks,
