Subject[PATCH v4 17/22] ARM: dts: exynos: Add initial support for Odroid XU board
Date
The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
from Samsung: the Exynos5410. Comparing the board to more popular now
Odroid XU3, the differences are:
1. Exynos5410 instead of 5422,
2. MIPI DSI LCD connector,
3. Main PMIC: Maxim 77802 instead of S2MPS11,
4. USB3503+LAN9730 instead of integrated LAN9514,
5. eMMC 4.5 instead of eMMC 5.0,

This patch adds initial support for the XU board with working basic
functions, eMMC/SD and USB (including attached ethernet adapter).
