From 261e1d5cc5ee994f17089d8f0d4f8443743d732d Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 15 Jan 2017 23:32:53 +0100 Subject: ARM64: dts: meson-gx: add the serial CTS and RTS pin groups MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds pinctrl group nodes for the CTS and RTS pins of each serial controller. This makes it possible to enable the CTS and RTS pins which are controlled by the serial controller hardware (through the meson_uart driver).
