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

Option 2: dynamic debug via kernel commandline (needs CONFIG_DYNAMIC_DEBUG)

dyndbg="func deferred_probe_work_func +p; func driver_deferred_probe_add +p"

Option 3: use "initcall_debug" kernel commandline
