From 138c2b2f175b781242342ee96fa125558c34a245 Mon Sep 17 00:00:00 2001 From: Sylvain Rochet Date: Sun, 16 Oct 2016 18:21:45 +0200 Subject: ARM: dts: at91: fixes dbgu pinctrl, set pullup on rx, clear pullup on tx Remove pullup on dbgu DTXD signal, it is a push-pull output thus the pullup is pointless. Add pullup on dbgu DRXD signal, it prevents the DRXD signal to be left floating and so consuming a useless extra amount of power in crowbarred state if nothing is externally connected to dbgu.
