Subject: [PATCH v2 22/22] ARM: dts: exynos: Add initial support for Odroid XU board
The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
from Samsung: the Exynos5410. Comparing now to more popular Odroid XU3
the differences are:
1. Exynos5410 instead of 5422,
2. DisplayPort,
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).
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
