This patch series provides cleanups that should facilitate extending the
ublox driver to more easily cover all device models. Points of
interest:
- provides model descriptors that can be extended to account for
differences between devices
- queries the device model directly instead of relying on
information from udev
- provides detection and rudimentary support for TOBY L4 modems
- updated LTE driver to be used across all ublox models
The TOBY L4 support is a work in progress and this is also to be extended to
the SARA-R4/N4 series. I currently only have a TOBY L4 available, so
I'm hoping that somebody with an L2 could give this a shake to make sure
nothing's been broken there.

New subject: [PATCH 02/14] ublox: drop vendor type for Toby L2 model
The 'Toby L2'-specific vendor type is used only to prevent the CMER
command from attempting to set mode '3'. For all u-blox models, mode
'3' is just an alias for mode '1'. As such, mode '1' can be used
in
place of mode '3', removing the model-specific quirk in favour of a
vendor-specific quirk.
With this change, the L2-specific vendor type is no longer needed.

New subject: [PATCH 03/14] ublox: make device selection more flexible
Many ublox modems can sit on either the USB bus or talk directly to a
UART. The udev plugin mostly takes care of figuring out what ports to
talk to and the protocol is common for all devices after that.
This patch simplifies the setup a bit:
i) There must always be an aux channel for communication with the modem
ii) The aux channel may be found behind the string Aux for USB modems
or Device for serial modems
iii) If the Modem string is set, use it; if not set, assume it's not
available.

New subject: [PATCH 05/14] ublox: query device model
Hi Denis,
Thanks for the review. I'm a bit baffled by some of the warnings you
are seeing... DOS line endings? Where did those come from... I don't
see them here.
Nonetheless, I'll send a quick resubmission that passes checkpatch.pl
and we'll take it from there.
Thanks,
Jonas

Have you tried running checkpatch.pl on these? There are too many
coding style violations for me to fix.
Here's a small sample:

New subject: [PATCH 06/14] ublox: add model flag HAVE_USBCONF
This flag should be set on devices that support multiple USB profiles
and will be used to determine whether or not querying USB profiles is
appropriate/necessary.

New subject: [PATCH 07/14] ublox: query USBCONF for applicable devices
The TOBY L2 series of modems presents a number of different
configurations with different throughtput characteristics. These
configurations are packaged up as USB profiles; moreover, changing the
profile actually changes the USB model ID so this is even more like
selecting a different "device" altogether. Nonetheless, all we need to
know is which profile is selected in order to set things up correctly
and this can be queried directly.
This patch adds a call to UUSBCONF for applicable modems in order to
query the USB configuration to find out which profile is active.

Some aspects of a device are detectable at runtime, like the USB profile
detection that was added in a patch preceding this one. This patch
switches the driver over from creating a new "vendor id" for each
profile to just setting a flag. This is more easily extensible as we
detect other features of the modem.

New subject: [PATCH 11/14] udevng: detect ublox TOBY L4
ttyACM0 (USB interface 02) is reportedly unreliable (breaking DHCP setup)
so the recommended approach is to use ttyACM2 (USB interface 06)
exclusively.

New subject: [PATCH 13/14] ublox: extend LTE driver
There are a couple of semi-independent changes here:
* use the 'vendor' parameter to pass the modem 'model'
* support TOBY L4 modem which uses a fixed CID for configuring the EPS
default bearer
* add the setup of authentication parameters that was recently added to
the atmodem LTE driver
