I tried to get access at motmdm, but no:

root@devuan:/home/user# minicom -D /dev/motmdm1
minicom: cannot open /dev/motmdm1: No such file or directory
root@devuan:/home/user# ls -al /dev/motmdm1
ls: cannot access '/dev/motmdm1': No such file or directory
root@devuan:/home/user# dmesg | grep motmd
root@devuan:/home/user# zcat /proc/config.gz | grep MDM
CONFIG_MFD_MOTMDM=y
CONFIG_SND_SOC_MOTMDM=y
CONFIG_PHY_MAPPHONE_MDM6600=y
root@devuan:/home/user# uname -a
Linux devuan 4.20.0-rc7-00304-gde109fe #19 SMP Sat Dec 22 20:16:19 CET
2018 armv7l GNU/Linux
root@devuan:/home/user#

Let me try to enable CONFIG_GNSS_MOTMDM. N_GSM also seems enabled.
 
Is there anything else I need to enable in .config?

Scary Solstice!
