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
