Do you have vibrations on d4 working?
I believe I have required drivers enabled, but no luck:

user at devuan:/sys/bus/platform/drivers$ ls pwm-vibrator/
bind  uevent  unbind
user at devuan:/sys/bus/platform/drivers$ ls omap-dmtimer-pwm/
bind  uevent  unbind
Have you checked probe deferrals?
Not really. Is there easier way to do that than adding printks in the
probe function? (I can go through dmesg tommorow).
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 at 4805d000 , and that one seems to be present.

user at devuan:/sys/bus/platform/devices$ ls 4805d000.gpio
driver				       driver_override  gpio
gpiochip5  modalias  of_node  power  subsystem  uevent
Sorry, something went wrong with merging this. The parent
of ti,omap-dmtimer-pwm and pwm-vibrator should be / and
not gpio6.
