From b859c1ef92fca08a3079d9ff81e0e0bf7980c855 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Thu, 30 May 2013 17:38:00 -0700 Subject: ARM: dts: OMAP3: beagle/overo: mux console UART, enable wakeup Ensure the console uart (UART3) on these boards is mux'd correctly, and IO ring wakeup is enabled. This is needed for serial console wakeups when using DT boot. Thanks to Florian Vaussard for suggestion to use preprocessor features.
