From 7aedca875074b33795bc77066b325898b1eb8032 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 2 Apr 2019 14:32:04 -0500 Subject: ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1 Some USB peripherals draw more power, and the sourcing regulator take a little time to turn on. This patch fixes an issue where some devices occasionally do not get detected, because the power isn't quite ready when communication starts, so we add a bit of a delay.
