Gobi 1000 devices have a different port layout, which wasn't respected
by the current driver, and thus it grabbed the QMI/net port.  In the
near future we'll be attaching another driver to the QMI/net port for
these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver
doesn't claim them.  This patch also prevents qcserial from binding to
interfaces 0 and 1 on 1K devices because those interfaces do not
respond.

No one uses them anymore, they should be using the safer
usb_serial_register_drivers() and usb_serial_deregister_drivers()
functions instead.

This patch (as1522) adds two new routines to the usb-serial core, for
registering and unregistering serial drivers.  Instead of registering
the usb_driver and usb_serial_drivers separately, with error checking
for each one, the drivers can all be registered and unregistered by a
single function call.  This reduces duplicated code.

More importantly, the new core routines change the order in which the
drivers are registered.  Currently the usb-serial drivers are all
registered first and the usb_driver is done last, which leaves a
window for problems.  A udev script may quickly add a new dynamic-ID
for a usb-serial driver, causing the corresponding usb_driver to be
probed.  If the usb_driver hasn't been registered yet then an oops
will occur.

The new routine prevents such problems by registering the usb_driver
first.  To insure that it gets probed properly for already-attached
serial devices, we call driver_attach() after all the usb-serial
drivers have been registered.

Along with adding the new routines, the patch modifies the "generic"
serial driver to use them.  Further patches will similarly modify all
the other in-tree USB serial drivers.

This fix changes the way baudrates are set on the CP210x devices from
Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV
command, and GET/SET_BAUDRATE command, while CP2104 and higher devices
only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in
kernel version 3.2.0 only implements the GET/SET_BAUDDIV command.

This patch implements the two new codes for the GET/SET_BAUDRATE
commands. Then there is a change in the way that the baudrate is
assigned or retrieved. This is done according to the CP210x USB
specification in AN571. This document can be found here:
http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart

Sections 5.3/5.4 describe the USB packets for the old baudrate method.
Sections 5.5/5.6 describe the USB packets for the new method. This
patch also implements the new request scheme, and eliminates the
unnecessary baudrate calculations since it uses the "actual baudrate"
method.

This patch solves the problem reported for the CP2104 in bug 42586,
and also keeps support for all other devices (CP2101/2/3).

This patchfile is also attached to the bug report on
bugzilla.kernel.org. This patch has been developed and test on the
3.2.0 mainline kernel version under Ubuntu 10.11.
