From ed0e7fbd8473c3fb07a0a9ece361879f6e45ad4a Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Fri, 14 Apr 2017 19:08:52 +0800 Subject: MLK-14638-2 ARM: dts: add off-on-delay for usdhc vmmc-supply regulator For the slot support SD3.0 card, during system suspend, if plug out the sd card, and insert another SD3.0 card, after system resume back, SD3.0 card can't be recognised as SD3.0 card, just SD2.0 card. This is bause the time delay between vmmc regulator off and on is too small, this patch add the oo-on-delay in vmmc-supply regulator, to assign proper delay value.
