Subject[PATCH 0/5] add USB Type-B connector driver
Date
Because the USB Connector is introduced and the requirement of
usb-connector.txt binding, the old way using extcon to support
USB Dual-Role switch is now deprecated, meanwhile there is no
available common driver when use Type-B connector.
This patch series introduce a Type-B connector driver and try
to replace the function provided by extcon-usb-gpio driver.
The main purpose of the patches is also to solve the Type-B
connector problem encountered in [1].
