From 9e186857c7f99600808b8ecb2fc0fa2adeddebaa Mon Sep 17 00:00:00 2001 From: Shaohui Xie <Shaohui.Xie@freescale.com> Date: Mon, 25 Mar 2013 07:30:15 +0000 Subject: [PATCH] powerpc/85xx: set USB2 default mode to 'device' for (super)hydra boards The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a second USB port that can be configured in either host, peripheral (aka device), or OTG (on-the-go) mode. When configured in host mode, if the port is connected to another USB host, damage to the board can occur. To avoid this, we change the default setting to peripheral mode. Ideally, we'd set it to OTG mode, but currently there is no OTG support for these boards. Setting the hwconfig variable will also update the device tree, and so Linux will configure the port for peripheral mode as well.
