Subject: [PATCH] usb: dwc2: disable power_down on Amlogic devices
Date:   Wed,  5 Sep 2018 18:55:13 +0400

Precedence: bulk

USB devices work when connected to Amlogic GXBB hardware before power
on, but not when connected after boot (hotplugged). With this patch
hotplugging works again. This change was copied from the Rockchip
patch here: (https://marc.info/?l=linux-usb&m=153205711616460&w=2)
