Subject: [PATCH 0/2] serial: add rs485-mux-gpio dt binding and support
Date: Mon, 20 Nov 2023 16:10:53 +0100 [thread overview]
Message-ID: <20231120151056.148450-1-linux@rasmusvillemoes.dk> (raw)
Some boards are wired so that they support both rs232 and rs485, with
a gpio controlling a mux connecting the SOC's pins to the appropriate
external circuitry. Instead of requiring the application to know about
such details and handle the gpio appropriately, allow it to be
described in device tree and let the serial core code handle it if
present.
Tested on a board based on imx8mp.
