Hi list, I'm working on a driver for a charger chip that also supports boost mode (supply power on VBUS in order to charge other devices). However, I'm not really sure what's the proper way to detect that we're in host mode or device mode in order to switch boost mode on. I saw some charger drivers register a notifier with the usb_phy and check for USB_EVENT_ID event. According to OTG specifications, if the ID pin is grounded the initial role should be host mode. But, not all USB PHY drivers throw this event. In fact, I only found one driver that does that: omap2430.c. Is there a more robust/generic way?
