Subject: [PATCH] ARM: dts: exynos: Enable PRNG and SSS for all Exynos4 devices
Date: Mon, 25 Apr 2016 11:29:56 +0200	[thread overview]
Message-ID: <1461576596-27844-1-git-send-email-k.kozlowski@samsung.com> (raw)

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.
