From ff11a79878a8b43394b296c06557033efd17b1ee Mon Sep 17 00:00:00 2001 From: satya priya Date: Mon, 14 Sep 2020 19:28:34 +0530 Subject: [PATCH] arm64: dts: qcom: sc7180: Improve the uart3 pin config for sc7180-idp Remove output-high from CTS and TX as this is not really required. During bringup to fix transfer failures this was added to match with console uart settings. Probably some boot loader config was missing then. As it is working fine now, remove it.
