From 209636b6784a1b6bd3968aebf03612467c33361c Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Mon, 24 Feb 2014 11:05:07 -0500 Subject: [PATCH] ARM: dts: keystone: add support for k2 Edison SoC and EVM Keystone2 Edison (K2E) is a Quad Cortex A15 based SoC with 1 DSP. It has standard peripherals such as i2c, spi, uart, timer, pcie, etc similar to k2hk, but without wireless hardwares. This patch add support for k2 Edison SoC and EVM. This re-uses the common keystone.dtsi to include common bindings across the various k2 devices.
