From 7fbec17465fca1df1b204eda79e07e52f9693c8d Mon Sep 17 00:00:00 2001 From: Franklin S Cooper Jr Date: Wed, 6 Dec 2017 09:53:04 -0800 Subject: ARM: dts: k2g-evm: Enable UART 2 66AK2G GP EVM has a Baseboard Management Controller (BMC) on board. This controller handles things like setting the SoCs boot mode along with controlling the on board character LCD display module. Enable UART2 which communicates with the BMC. This enables userspace applications to display something on the onboard LCD controlled by the BMC.
