From 05306b848b367e326dc76e7552192056338ac6ad Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 25 May 2017 09:15:58 -0700 Subject: ARM: dts: Configure USB host for 37xx-evm Looks like nobody bothered to configure USB host for 37xx-evm when we converted things to device tree, so let's add it. This is similar to beagleboard configuration with few extra quirks to configure the port. And as with beagleboard, OHCI won't work because there is no USB LS/FS PHY. A HS USB hub is needed to use devices like keyboard and mice.
