Subject: [PATCH 2/4] ARM: dts: aspeed: ethanolx: Configure RTS/CTS for UART1
Date: Sat, 11 Jun 2022 12:58:26 +0300 [thread overview]
Message-ID: <20220611095828.1090-3-aladyshev22@gmail.com> (raw)
In-Reply-To: <20220611095828.1090-1-aladyshev22@gmail.com>
UART1 is used for connection to the main EPYC CPU. Besides the main
TX/RX signals this connection has flow control signals RTS/CTS,
therefore configure this pins on the BMC side.
