From b5977f389d9ec7b5ffdc37ca6f2266e05295a552 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 20 Jun 2015 17:40:07 +0200 Subject: [PATCH] ARM: dts: sunxi: Add regulator-boot-on to usb host port regulator nodes u-boot will have turned on the power to the usb host ports, so mark them as regulator-boot-on, this stops the power on the ports from temporarily getting turned off during boot, causing issues with e.g. usb powered harddisks.
