Ok, I should have all that enabled. But droid4-ngsm still fails:
user@devuan:/my/droid4-ngsm$ sudo ./droid4-ngsm Starting ngsm.. Testing ngsm.. Could not open /dev/gsmtty1: Level 2 halted Trying to start ngsm again: Level 2 halted Starting ngsm..
commit 984c7706ff180e33096c57183435d925cb644576 says:
ARM: dts: omap4-droid4: Configure uart1 pins
These are needed to use the n_gsm driver for TS 27.010 UART multiplexing. Note that support for the OOB wake gpio is still missing so the UART is not yet usable for n_gsm.
...am I still missing the OOB wake gpio support?
