From 686c47f1300534439fd550e4cbfe1776abceab5a Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Tue, 1 Dec 2015 15:54:56 +0200 Subject: ARM: dts: am437x: cm-t43: add basic support for sbc-t43 Add basic support for SBC-T43: a CM-T43 based single board computer. CM-T43 is an AM437x based System-on-Module designed to serve as a building block in embedded applications. SBC-T43 is composed of CM-T43 module on top of the SB-SOM-T43 baseboard. Basic support includes UART, GPIO, and I2C.
