From mboxrd@z Thu Jan 1 00:00:00 1970 From: marex@denx.de (Marek Vasut) Date: Sun, 17 Nov 2013 04:04:50 +0100 Subject: [PATCH] ARM: dts: imx53: Add USB support for M53EVK Message-ID: <1384657490-5925-1-git-send-email-marex@denx.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add USB support for M53EVK. The configuration is such that USB Host1 port is used as Host and the USB OTG port is used as Peripheral thus far. Once OTG is properly fixed, the OTG will be further adjusted.
