From 8c07f664a6c48bfc44ce9352c8c2fba55f1d108b Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 12 Mar 2015 15:54:26 +0100 Subject: ARM: at91/dt: introduce atmel,-dbgu The DBGU is not a simple UART and we need to be able to distinguish it from the other UARTs, in particular to get its address and check the chip id.
