Subject: [PATCH 0/3] ARM: dts: Enable Exynos RNG module

Hi,


The patchset adds necessary clock from Security SubSystem (SSS)
and enables the PRNG module of Exynos for Trats2 board.

The first patch (clock) is required for other ones so please
take everything in one step.

The actual Device Tree support (and compatible) was sent in separate
patch:
 - https://patchwork.kernel.org/patch/7432891/
 - http://marc.info/?l=linux-crypto-vger&m=144522952725052&w=2

The device can be tested (after applying both patchsets) with:
$ echo exynos > /sys/class/misc/hw_random/rng_current
$ dd if=/dev/hwrng of=/dev/null bs=1 count=16


Best regards,
Krzysztof
