From 39dd00fc5dbae60c4165a06b50420a36270c68ab Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Thu, 26 Jul 2018 19:47:24 +0800 Subject: drivers: regulator: fixed: add u-boot, off-on-delay-us Add u-boot,off-on-delay-us for fixed regulator. Depends on board design, the gpio regulator sometimes connects with a big capacitance. When need to off, then on the regulator, if there is no enough delay, the voltage does not drop to 0, so introduce this property to handle such case.
