From 5fc0b42a98556bd9f01cecc6a64fcbd15ec363f0 Mon Sep 17 00:00:00 2001 From: AnilKumar Ch Date: Fri, 22 Jun 2012 15:10:48 +0530 Subject: [PATCH] arm/dts: Add initial DT support for AM33XX SoC family Add device tree source include file for the AM33XX SoC family. An additional .dtsi file is created to describe the generic AM33XX CPU module like intc, ocp. Actual selection of available peripherals is handled in seperate .dts files using this am33xx.dtsi generic header file.
