From e06f1a9ed7ebff170ba05d2606d079fb36c6a52d Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Wed, 31 Oct 2012 12:24:48 -0600 Subject: [PATCH] ARM: zynq: dts: split up device tree The purpose of the created zynq-7000.dtsi file is to describe the hardware common to all Zynq 7000-based boards. Also, get rid of the zynq-ep107 device tree, since it is not hardware anyone can purchase. Add a zc702 dts file based on the zynq-7000.dtsi. Add it to the dts/Makefile so it is built with the 'dtbs' target.
