Sorry I must have confused you. There are two modules in the PMIC that
are doing detection here. The charger module is detecting the VBUS event
and this misc module is detecting the ID pin. I'm not sure why they're
two different blocks, but it is what it is in the hardware.

OK. Can the MISC block do anything else other than USB ID?

Yes.

Does the USB ID interrupt come on a different line than the charger interrupt?

Yes.

OK. Is it better to have this driver somewhere in drivers/mfd or drivers/misc if the
other function doesn't need/use extcon?

If/when the other functionality is used by the kernel we can consider
moving this driver somewhere else. As there currently isn't any other
usage of this device node I implemented it in the extcon directory to be
explicit about the usage.
