| Subject: ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1 |
| |
| From: Adam Ford <aford173@gmail.com> |
| |
| commit 7aedca875074b33795bc77066b325898b1eb8032 upstream. |
| |
| 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") |
