Subject: [PATCH AUTOSEL 4.4 03/10] ARM: dts: imx6: phyFLEX: Fix UART hardware flow control
Date: Wed, 14 Jul 2021 15:48:26 -0400 [thread overview]
Message-ID: <20210714194833.56197-3-sashal@kernel.org> (raw)
In-Reply-To: <20210714194833.56197-1-sashal@kernel.org>
From: Primoz Fiser <primoz.fiser@norik.com>
[ Upstream commit 14cdc1f243d79e0b46be150502b7dba9c5a6bdfd ]
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.
