+What:  /sys/devices/platform/_UDC_/udc/_UDC_/is_dualspeed file and
+       is_dualspeed line in /sys/devices/platform/ci13xxx_*/udc/device file.
+When:  3.8
+Why:   The is_dualspeed file is superseded by maximum_speed in the same
+       directory and is_dualspeed line in device file is superseded by
+       max_speed line in the same file.
+
+       The maximum_speed/max_speed specifies maximum speed supported by UDC.
+       To check if dualspeeed is supported, check if the value is >= 3.
+       Various possible speeds are defined in <linux/usb/ch9.h>.
