Now that Maxim Integrated MAX3355 'extcon' driver and device tree bindings
are upstream along with the 'extcon' hook in the Renesas USBHS driver, we
can add MAX3355 device node to the Porter device tree and properly refer
to it from the USBHS node instead of using "renesas,enable-gpio" property
which only allowed checking the USB ID pin at the driver probe time; now
this pin's state can be monitored dynamically!

I tested this patch on Porter, but interrupt of "usb-otg" didn't happened
even if I connected/disconnected a usb convert cable (usb micro-ab to A).
Remarks: I confirmed that the usb convert cable worked correctly on other board.
I guess I have the same cable and IRQs do happen for me when I connect and
disconnect it (as it should be).
Do I need other settings for this?
No evident answer to that, your logs show that MAX3355 driver was enabled...

I guess these states doesn't change even if you insert your cable?
They also do change for me.
