+Subject: arm64: dts: imx8mm-beacon: Enable RTS-CTS on UART3
+
+From: Adam Ford <aford173@gmail.com>
+
+commit 4ce01ce36d77137cf60776b320babed89de6bd4c upstream.
+
+There is a header for a DB9 serial port, but any attempts to use
+hardware handshaking fail.  Enable RTS and CTS pin muxing and enable
+handshaking in the uart node.
