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
