commit 102cd909635612c0be784a519651954a7924c786 upstream.
|
||
|
|
|
||
|
|
SIMCOM are reusing a single device ID for many (all of their?)
|
||
|
|
different modems, based on different chipsets and firmwares. Newer
|
||
|
|
Qualcomm chipset generations require setting DTR to wake the QMI
|
||
|
|
function. The SIM7600E modem is using such a chipset, making it
|
||
|
|
fail to work with this driver despite the device ID match.
|
||
|
|
|
||
|
|
Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM
|
||
|
|
modems using this specific device ID. This is similar to what
|
||
|
|
we already have done for another case of device IDs recycled over
|
||
|
|
multiple chipset generations: 14cf4a771b30 ("drivers: net: usb:
|
||
|
|
qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201")
|
||
|
|
|
||
|
|
Initial testing on an older SIM7100 modem shows no immediate side
|
||
|
|
effects.
