+Date: Feb 2014
+Contact: Li Jun <b47624@freescale.com>
+Description:
+ Can be set and read.
+ Set a_bus_req(A-device bus request) input to be 1 if
+ the application running on the A-device wants to use the bus,
+ and to be 0 when the application no longer wants to use
+ the bus(or wants to work as peripheral). a_bus_req can also
+ be set to 1 by kernel in response to remote wakeup signaling
+ from the B-device, the A-device should decide to resume the bus.
+
+ Valid values are "1" and "0".
+
+ Reading: returns 1 if the application running on the A-device
+ is using the bus as host role, otherwise 0.

+ The a_bus_drop(A-device bus drop) input is 1 when the
