(I can go through dmesg tommorow). >=20 > Option 1: https://lkml.org/lkml/2018/7/8/63 I tried this methodq, and no luck. static int pwm_omap_dmtimer_probe(struct platform_device *pdev) does not seem to be called. Its parent is gpio@4805d000 , and that one seems to be present. user@devuan:/sys/bus/platform/devices$ ls 4805d000.gpio driver driver_override gpio gpiochip5 modalias of_node power subsystem uevent So I'm now confused.
