From mboxrd@z Thu Jan 1 00:00:00 1970 From: tero.jaasko@gmail.com (Tero Jaasko) Date: Thu, 25 Oct 2012 18:01:00 +0300 (EEST) Subject: [PATCH] arm: kirkwood: add support for ZyXEL NSA310 Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hello, following patch adds support for the ZyXEL NSA310 NAS box. It has been tested and developed in a linux-stable/linux-3.6.y tree, up to 3.6.2. As mentioned in commit, the code is derived from the openwrt.org's repository. I have only done the device tree conversion. I have tested and used it on my NAS without trouble for a while. Testing of nand and adt7476 was limited to verifying that they are probed as I have no use for them. In order to use the kernel with stock uBoot, one needs to build with "make zImage modules dtbs", "cat arch/arm/boot/kirkwood-nsa310.dtb >> arch/arm/boot/zImage" "make uImage" sequence. --- >>From f31af66eadc0df17bb75c8e5607d56ce6e2ef899 Mon Sep 17 00:00:00 2001 From: Tero Jaasko Date: Mon, 22 Oct 2012 22:43:37 +0300 Subject: [PATCH] arm: kirkwood: add support for ZyXEL NSA310 Bring in the support for ZyXEL NSA310 NAS box. Code is mostly imported from the openwrt.org, (https://dev.openwrt.org/browser/trunk/target/ linux/kirkwood/patches-3.3/202-zyxel-nsa-310.patch?rev=31673). Original code is converted to use flattened device tree descriptions for the support for serial uart, sata, gpio keys and gpio leds.
