From 9acb15e1dcd54ef32b94e7a03ad70fc0a8ad69f4 Mon Sep 17 00:00:00 2001 From: Ryan Harkin Date: Tue, 23 Jan 2018 12:37:30 +0000 Subject: [PATCH] ARM: dts: imx7s-warp: enable uart6 on mikroBus This patch configures the board to output UART6 to the mikroBus. The NXP WaRP7 board can route UART6 to the mikroBus, where an RS232 click board can be plugged in to get an additional serial port.
