From 1ac49427b566ba9a73d1bf9cc1ffbc5c45ca30c5 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Mon, 2 Oct 2017 08:39:34 +0200 Subject: ARM: dts: exynos: Add support for Hardkernel's Odroid HC1 board Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI, no eMMC, no built-in USB3.0 hub, no extension port pins, and no GPIO button. USB3.0 ports are used for built-in JMicron USB to SATA bridge and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.
