[PATCH v2 2/7] doc: usb: ci-hdrc-usb2: Add pinctrl properties definition

Some hardware implementations require to configure pins differently according to the USB role (host/device), this can be an update of the pins routing or a simple GPIO value change. This patch introduces new optional "host" and "device" pinctrls. If these pinctrls are defined by the device, they

[PATCH v2 5/7] usb: chipidea: Fix otg event handler

At OTG work running time, it's possible that several events need to be addressed (e.g. ID and VBUS events). The current implementation handles only one event at a time which leads to ignoring the other one. Fix it. Signed-off-by: Loic Poulain --- v2: no change drivers/usb/chipidea/otg.c | 9

[PATCH v2 3/7] usb: chipidea: Support generic usb extcon

Add compatibility for extcon-usb-gpio which can handle more than one cable per instance, allowing coherency of USB cable states (USB/USB-HOST). These states can be generated from ID or/and VBUS pins. In case only one extcon device is associated to the USB device, and this device supports USB and
