Ivanov" , balbi@ti.com, kishon@ti.com, Bartlomiej Zolnierkiewicz List-Id: devicetree@vger.kernel.org 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.
