[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This provides a series of patches contributed by several people to
do correct charger detection and solve issues that came along with
the charger detection implementation.

USB_EVENT_NONE notification is sent only when a PC cable/CDP cable or
a device connected to MUSB is detached.

USB_EVENT_VBUS notification is sent only when a PC cable/CDP cable or
a device is connected to MUSB.

commit id: cc39c6a9bbdebfcf1a7dee64d83bf302bc38d941

This patch series is developed and tested on top of Heikki Krogerus
patch series (version4) [1]

Basic Testing:
Tested with gadget zero enabled for charger detection (PC/DCP). Data transfer testing
is done on both omap4 and omap3 with ./testusb. Tested for device enumeration when a
device is connected to MUSB.
