Hi!

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.

Ok, got it to probe... after dts fix and adding EPROBE_DEFFER to
driver.

Hmm sorry if I did a mismerge on the above. A note to
myself to stop applying patches that apply with fuzz,
that is clearly dangerous with dts files with lots
of similar named properties.

Yep, so I have two patches that make the device appear, but vibrations
still do not work for me.

a) any ideas how to debug that / get them to work?

b) do you want the patches anyway?

Regards,
