[PATCH] ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1

From: Adam Ford
Date: Tue Apr 02 2019 - 15:32:22 EST


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.

Fixes: 1c207f911fe9 ("ARM: dts: imx: Add support for Logic PD
i.MX6QD EVM")
