[PATCH v3 21/27] ARM: dts: exynos: Add USB to Exynos5410

Krzysztof Kozlowski krzk at kernel.org
Tue May 10 13:09:24 PDT 2016


Move USB 3.0 DWC and 2.0 EHCI/OHCI nodes from exynos5420.dtsi to
exynos54xx.dtsi common for entire family. For Exynos542x/5800 this
should not have functional impact but for Exynos5410 this effectively
adds USB support.
