[PATCH] serial: Add Option GTM681W to qcserial device table.

[Richard Weinberger]

The Option GTM681W uses a qualcomm chip and can be
served by the qcserial device driver.

Should it also be added to the qmi_wwan driver?

Don't know. But I can happily test it. :)
Can you please explain me how to use the qmi_wwan driver?
I've never used it.

Thanks,

The QMI management protocol is delegated to userspace using a
/dev/cdc-wdmX character device.  So you need a userspace component to
test the driver, like for example libqmi. See 
http://sigquit.wordpress.com/2012/08/20/an-introduction-to-libqmi/ for a
short intro.

This library is packaged in Debian.  Don't know the status of other
distros. 

The driver supports dynamic device IDs, so if you have qcserial bound to
all serial ports, and there is a QMI interface with no driver bound yet,
then testing should be as easy as

 modprobe qmi_wwan
 echo "0af0 8120" >/sys/bus/usb/drivers/qmi_wwan/new_id
 qmicli -d /dev/cdc-wdm0 --dms-get-manufacturer

Various marketing collateral suggests the 681W is a Gobi3K and thus it
most certainly should also get added to qmi_wwan.  lsusb -v output for
it would be helpful too I think?
