From d5e9fe8462d3f596a420cc1a25a01928777f139b Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 10 Jun 2013 11:33:31 -0400 Subject: [PATCH] ARM: dts: keystone: Add minimal Keystone SOC device tree data Add minimal device tree data for Keystone2 based SOCs. Patch contains mainly ARM related SOC data and nothing about EVM specific yet.
