From mboxrd@z Thu Jan 1 00:00:00 1970 From: andrej@inversepath.com (andrej at inversepath.com) Date: Fri, 24 Apr 2015 15:33:45 +0200 Subject: [PATCH] ARM: dts: imx53: add support for USB armory board Message-ID: <1429882425-24514-1-git-send-email-andrej@inversepath.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Andrej Rosano 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.
