Subject: [RFC v4 0/7] extcon: usb-gpio: fixes and improvements

Hi,


Some time ago, Robert tried to add VBUS detection to extcon-usb-gpio
driver [1].  There was a discussion about patch #2 ("extcon: usb-gpio:
add support for VBUS detection").

The final conclusion was that Chanwoo will add VBUS/ID notifiers [2].
That unfortunately never happened so this patchset is a follow up.

1. Add VBUS/ID cable state notifiers to extcon, so USB controllers
   could use it.
2. Add VBUS detection to extcon-usb-gpio driver.

Some parts are based on old Robert's work, some are new, some are
reworked.


Best regards,
Krzysztof
