Title:
[SRU] Patches needed for Telit modems used in IOT systems
Status in HWE Next:
Won't Fix
Status in modemmanager package in Ubuntu:
Won't Fix
Bug description:
We have been informed by Telit that additional patches are required to
enable their WWAN modems. Those patches are already upstreamed in
modemmanager but not yet in Xenial.
[Impact]
Since this device is needed for 16.04 project, we need SRU for modemmanager.
The patches are:
* telit: add modem_power_down to telit plugin
commit: 14e47710561b2021b79814afa5ecd6b2abc4fad0
This patch implements ModemManager feature set-power-state-low that is the
common approach to put
the modem in +CFUN=4 state
* telit: add modem_reset to telit plugin
commit: 7978225934dc87bc74fac4d79a1080bc0501e581
This commit solves the following issue:
The reset command (mmcli –m 0 –r) needs to tie up with the AT command
(AT#REBOOT)
* telit: SIM unlock retries field
Main commit: c4ffe572aeeefac240f16822ca1d2d258f78ad8d

aae96778c54a59dcf3955c2d81bee393c0348077
This patch is necessary to fill the field “Unlock retries”, visible when
mmcli -m 0 is run.
* telit: add load supported bands interface
Main commit: 70b8ec1a88477eea3a2f569a83fc270ccaff9504
Related coding style commits: 3911ea5a0f6b26e12a3586c75d72bb2c5820e3c1
This patch adds supported bands information.
* dell: fixed cgmi_retries in dell_custom_init
commit: 8a386218690aeff7e2c923a14f91da7bbc046ed2
This patch solves a random never-ending loop during port probing.
[Test Case]
We have the hardware to verify.
[Regression Potential]
By looking at those commits, they are self-contained to the telit plugin.
These patches were asked by Telit to backport (we have the specification
document from Telit but that's not public)
