I agree that we should use a regulator for the vbus power.
i will make that change. However, im not so sure about using the
regulator for the overcurrent handling. There seems to be no other
driver doing this, and as you mention, we would need to change the regulator
framework, which might not be justifiable. I think there is not another way
to handle the over current notification other than powering the port off.
how about using regulator for vbus, but keeping gpio for overcurrent
For the usersapce handling you describe above, maybe we should be able to
listen for an usb overcurrent uevent in userspace? it seems this
question was asked
a couple of years back, but im not sure what the conclusion was. In any case,
we could have DT and non-DT based ohci-da8xx working,
And could work on a uevent notification for the scenario you describe
i think is not specific to the ohci-da8xx.
