From a90921185fe5db3e02aecf473f0c54343ae17191 Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Tue, 5 Nov 2013 12:40:22 +0100 Subject: [PATCH] ARM: add Armada 1500-mini and Chromecast device tree files This adds very basic device tree files for the Marvell Armada 1500-mini SoC (Berlin BG2CD) and the Google Chromecast. Currently, SoC only has nodes for cpu, some clocks, l2 cache controller, local timer, apb timers, uart, and interrupt controllers. The Google Chromecast is a consumer device comprising the Armada 1500-mini SoC above.
