Uwe Bonnes 309427b635 USB: Add new FT232H chip to drivers/usb/serial/ftdi_sio.c 
appended patch adds support for the new FTDI FT232H chip. This chip is a
single channel version of the dual FT2232H/quad FT4232H, coming with it's
own default PID 0x6014 (FT2232H uses the same PID 0x6010 like FT2232C,
FT4232H has also it's own PID).

The patch was checked on an UM232H module and a terminal program with TX/RX
shorted to that typing in the terminal reproduced the characters.

* 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]

* follows:
* - set tty->termios->c_cflag speed to B38400
* - 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
