/*
 * The 8U232AM has the same API as the sio except for:
 * - it can support MUCH higher baudrates; up to:
 *   o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
 *   o 230400 at 12MHz
 *   so .. 8U232AM's baudrate setting codes are different
 * - it has a two byte status code.
 * - it returns characters every 16ms (the FTDI does it every 40ms)
 *
 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
 * the earlier FT8U232AM and FT8U232BM.  For now, include all known VID/PID
 * combinations in both tables.
 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
 * but I don't know if those ever went into mass production. [Ian Abbott]

	 *    - set your real speed in tty->alt_speed; it gets ignored when
	 *      alt_speed==0, (or)
	 *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
	 *	follows:
	 *      flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
	 *	this just sets alt_speed to (HI: 57600, VHI: 115200,
	 *	SHI: 230400, WARP: 460800)
	 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
	 * 3. You can also set baud rate by setting custom divisor as follows
	 *    - set tty->termios->c_cflag speed to B38400
	 *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
	 *	follows:
	 *      o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
	 *      o custom_divisor set to baud_base / your_new_baudrate
	 * ** Step 3 is done courtesy of code borrowed from serial.c
	 *    I should really spend some time and separate + move this common
	 *    code to serial.c, it is replicated in nearly every serial driver
