[PATCH] ARM: dts: exynos: Enable PRNG and SSS for all Exynos4 devices
From: Krzysztof Kozlowski
Date: Mon Apr 25 2016 - 05:30:16 EST
There is no external dependency for Security SubSystem (SSS) block so
the nodes for Pseudo Random Number Generator and AES hardware
acceleration can be enabled always for all Exynos4 devices.
