Subject: [PATCH] ARM: dts: imx: add CX9020 Embedded PC device tree

From: [email-masked] (linux-kernel-dev at beckhoff.com)
Date: Wed, 12 Jul 2017 11:04:08 +0200

From: Patrick Br?nn <[email-masked]>

The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc
