Sometimes there's a real OTG chip behind the USB ID signal mapped to a GPIO

s/thru/through ?
"Thru" is valid English.
This chip also has the SHDN# pin which should be driven high for the normal
operation and low to save power; it is connected to a GPIO pin as well on,
hence we'll have to teach the driver to parse the new optional device tree
property, "enable-gpio"...
This patch description includes the double space between words. Also, I think
So what?
you need to write the patch description again for formal style.
Not sure I understand you.
This patch adds the specific 'enable-gpio' pin to express the SHDN#pin for
MAX3355E.
I think it is not regular and standard case because maybe USB specification
don't include the SHDN#pin information.
Certainly, it's not a USB pin.
I think it not appropriate way.
Instead, you better to make the MAX3355 extcon driver to support this case.
OK, just didn't want to duplicate most of this driver there...
Thanks,
