Subject: [PATCH] ARM: dts: imx6: phyFLEX: Fix UART hardware flow control
Date: Mon, 12 Apr 2021 08:24:50 +0200 [thread overview]
Message-ID: <20210412062450.1430199-2-primoz.fiser@norik.com> (raw)
In-Reply-To: <20210412062450.1430199-1-primoz.fiser@norik.com>
Serial interface uart3 on phyFLEX board is capable of 5-wire connection
including signals RTS and CTS for hardware flow control.
Fix signals UART3_CTS_B and UART3_RTS_B padmux assignments and add
missing property "uart-has-rtscts" to allow serial interface to be
configured and used with the hardware flow control.
