Subject: [PATCH] ARM: dts: imx53: add support for USB armory board
Date: Fri, 24 Apr 2015 15:33:45 +0200 [thread overview]
Message-ID: <1429882425-24514-1-git-send-email-andrej@inversepath.com> (raw)
From: Andrej Rosano <andrej@inversepath.com>
Add support for Inverse Path USB armory board, an open source
flash-drive sized computer based on Freescale i.MX53 SoC.
http://inversepath.com/usbarmory
As the device can work in either USB device mode or USB host mode,
two different device tree file are needed along with one common
include file.
