From 47e0920cca5354acf7185b7a28e630f84b72bd16 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 22 Dec 2014 16:30:14 -0600 Subject: [PATCH] ARM: dts: add support for AM437x IDK The AM437x Industrial Development Kit (IDK) is an application development platform targeted at industrial communication and control applications. It comes with a 3-phase motor driver, PROFINET, PROFIBUS and a few other industrial communication interfaces. The board has 1GiB of DDR3 RAM, QSPI NOR flash, a 100% discrete power design (no PMIC) and an on-board 2MP camera (not supported with Linux as of this writing).
