I got this in the kernel log:
[ 0.756042] omap-dmtimer-pwm dmtimer-pwm: dmtimer pdata structure NULL
[ 0.756134] omap-dmtimer-pwm: probe of dmtimer-pwm failed with error -22
the probe function has to wait until omap_dm_timer_probe() in
clocksource/timer-ti-dm.c has initialized pdata, so defer probing
Fixes: b7290cf6ff78 (pwm: pwm-omap-dmtimer: Adapt driver to utilize dmtimer pdata ops)
