From 446e9c63161519902a251c3670d2fbb455146475 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Wed, 14 May 2014 23:45:58 +0200 Subject: ARM: tegra: initial add of Colibri T30 This patch adds the device tree to support Toradex Colibri T30, a computer on module which can be used on different carrier boards. The module consists of a Tegra 30 SoC, two PMIC, DDR3L RAM, eMMC, a LM95245 temperature sensor and an AX88772B USB Ethernet Controller. Furthermore, there is a STMPE811 and SGTL5000 audio codec which are not yet supported. Anything that is not self contained on the module is disabled by default. The device tree for the Evaluation Board includes the modules device tree and enables the supported pheripherials of the carrier board (the Evaluation Board supports almost all of them).
