From mboxrd@z Thu Jan 1 00:00:00 1970 From: dinguyen@altera.com (dinguyen at altera.com) Date: Thu, 31 Jan 2013 11:05:40 -0600 Subject: [PATCHv2 for soc 1/4] arm: socfpga: Add new device tree source for actual socfpga HW In-Reply-To: <1359651943-21752-1-git-send-email-dinguyen@altera.com> References: <1359651943-21752-1-git-send-email-dinguyen@altera.com> Message-ID: <1359651943-21752-2-git-send-email-dinguyen@altera.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Dinh Nguyen Up to this point, support for socfpga has only been on a virtual platform. Now that actual hardware is available, we add the appropriate device tree source files.
