Subject: [PATCH 1/2] regulator: palmas: configure enable time for LDOs
Date: Tue, 10 Sep 2013 16:48:07 +0530 [thread overview]
Message-ID: <1378811888-2268-1-git-send-email-ldewangan@nvidia.com> (raw)
As per datasheet (Referred TPS65913), the on-time for LDO is
500micro second. If LDO6 is in vibrator mode then the on-time
is 2000us.
Set the enable_time on regulator descriptor accordingly.
