Something is weird here...DEFAULT_AUTOSUSPEND_DELAY is defined as (30*HZ) which would appear to be jiffies (ticks per second) and NOT msecs. However, pm_runtime_set_autosuspend is clearly expecting msecs. So this seems to conflict. By default 30*HZ for omap would be 30*128 = 3840ms so not quite 4 seconds.
What were you intending here? Cheers Jon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
