However that is what happens, this is my callstack after adding some prints: sa11x0_pcmcia_init sa11x0_drv_pcmcia_probe soc_pcmcia_init_one soc_pcmcia_add_one soc_pcmcia_hw_init sa11x0_pcmcia_hw_init soc_pcmcia_add_one: pcmcia HW init failed sa11x0-pcmcia: probe of sa11x0-pcmcia failed with error -2 It bails out when trying to get the "reset" gpio. I'm trying to figure out how this can happen. On the plus side: this minor snag is all the problems I have. All other GPIOs work exactly as they should.
