	  Char driver interface for SoC Diagnostic information. The DIAG Char

	  driver provides diag forwarding to user space and SoC Peripherals.

	  This enables diagchar for maemo usb gadget or android usb gadget

	  Diag over USB enables sending DIAG traffic over a USB transport. When

	  the USB endpoints become available, the DIAG driver will enable Diag

	  traffic over USB. This allows for host side tools to parse and display

	  Diag traffic from the USB endpoint.

	  endpoints become available, this bridge driver enables DIAG

	  over MHI or SMUX to communicate with the remote processors and

	  receive/send diag traffic to remote processors.
