Should not be a user-visable option. Drivers using it should select it
Why not? It's up to the (final) user to use it, or not.
or otherwise cause it to be enabled.
Why should this be driver-specific? Shouldn't this just work with all drivers?
It does once enabled.
I think what Grant refers to is that there has to be a driver which implements
the actual overlay insertion and removal (ie calls the new API functions),
and that the Kconfig option for this driver should select OF_OVERLAY
instead of depending on it.
