Everything (except of the first line) is because you have CONFIG_DEBUG_GPIO enabled and nokia-modem returns -EPROBE_DEFER until all drivers are available, so GPIOs will be acquired again the next time the drivers tries to probe. > Also, I now realize there is a forced nokia_modem Kconfig dependency > to cmt_speech.

I think CMT_SPEECH and SSI_PROTOCOL should actually be hidden and autoselected by NOKIA_MODEM. -- Sebastian
