Ondrej Zary 5128a66c66 USB: ark3116: add IrDA support for Gembird UIR-22
Add IrDA support to ark3116 driver.  This makes Gembird UIR-22 USB to IrDA
adapter work (vendor ID 0x18ec, device ID 0x3118).  This adapter contains
ARK3116T USB serial chip and an IrDA transceiver, thus a command like
"irattach /dev/ttyUSB0 -s" is needed.

All magic numbers were captured using usbsnoop from windows driver that
came with the device.

Alan Cox fe1ae7fdd2 tty: USB serial termios bits
Various drivers have hacks to mangle termios structures. This stems from
the fact there is no nice setup hook for configuring the termios settings
when the port is created

Alan Cox 95da310e66 usb_serial: API all change
USB serial likes to use port->tty back pointers for the real work it does and
to do so without any actual locking. Unfortunately when you consider hangup
events, hangup/parallel reopen or even worse hangup followed by parallel close
events the tty->port and port->tty pointers are not guaranteed to be the same
as port->tty is the active tty while tty->port is the port the tty may or
may not still be attached to.

So rework the entire API to pass the tty struct. For console cases we need
to pass both for now. This shows up multiple drivers that immediately crash
with USB console some of which have been fixed in the process.

Longer term we need a proper tty as console abstraction

Alan Cox a5b6f60c5a usb serial: more fixes and groundwork for tty changes
- If a termios change fails due to lack of memory we should copy the
   old settings back over as the device has not changed
 - Note various locking problems
 - kl5kusb105 had various remaining tty flag handling problems
 - Make safe_serial use tty_insert_flip_string not open coded loops
 - set termios speed properly in usb_serial

Alan Cox 568c24adea USB: serial: ark3116.c: Mixed fixups
o	Don't parse the cflag for baud rates, its not valid to do so
	any more and this driver got it wrong anyway
o	Don't do clever termios change checks in drivers and get them
	wrong (arguably we should do some smart ones in the tty core but
	stty to change nothing is *not* a common or critical path

I don't have the hardware so if you can test this carefully please do. I
thought fixing it up this far was better than marking it and other bits of
USB serial && BROKEN

Jan Engelhardt b268f484f9 USB: Fix debug output of ark3116
Fix debug output. Previously, it would output "0xFFFFFFB0" on 32-bit
archs (and probably "0xFFFFFFFFFFFFFFB0" on 64-bits), because buf is
taken as signed char, which is promoted to signed int, while %x always
expects an unsigned int.

Johannes Hölzl d9b1b78773 USB serial: add driver pointer to all usb-serial drivers
Every usb serial driver should have a pointer to the corresponding usb driver.
So the usb serial core can add a new id not only to the usb serial driver, but
also to the usb driver.

Also the usb drivers of ark3116, mos7720 and mos7840 missed the flag
no_dynamic_id=1. This is added now.

Alan Cox 606d099cdd [PATCH] tty: switch to ktermios
This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

Werner Lemberg 2f430b4bba USB: ark3116: Add TIOCGSERIAL and TIOCSSERIAL ioctl calls.
Add (dummy?) support for TIOCGSERIAL and TIOCSSERIAL ioctl calls to the USB
serial driver file `ark3116.c'.  This is sufficient for me to run wvdial
successfully, receive my email, and do webbrowsing with firefox.  On the
other hand, running the cvs program to update archives seems not to work,
and the traceroute command sometimes says

  send failed: No buffer space available

Looks like a buffering problem...  My knowledge of serial device drivers is
zero, so I can't fix this -- I just did a cut'n'paste from other USB serial
drivers...
