Subject: Issue seen with FET re-enable during auto discharge time

Hi Mark,
In one of our system, we are using TPS65090 which has FET switches for  
power control. This has also the auto discharger resistance for turning 
-off.

We observed that when we disable the FET and re-enable before it 
completely off (during power discharge time), it does not get enabled. 
It enable only if wait for it to completely off.

Does this mean we should also provide the disable time for tuning off 
(optional) so that disable_regulator() should return after actually 
tuning off?
In downstream, we stressed this after putting delay and it worked fine.

Thanks,
Laxman
