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
