[PATCH v2 1/5] ARM: zynq: dts: split up device tree

Josh Cartwright
2012-11-08T19:54:15Z

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.
