Subject: [PATCH] ARM: dts: imx: ventana: add RS485 txen gpio support
Date: Wed, 29 Jun 2016 06:38:24 -0700 [thread overview]
Message-ID: <1467207504-5218-1-git-send-email-tharvey@gateworks.com> (raw)
The GW54xx, GW53xx, and GW52xx all have an RS485 transceiver that uses an
IMX GPIO for the TX enable of the transceiver. Declare this properly.
