SubjectRe: [PATCH 0/3] ARM: dts: Enable Exynos RNG module
From
Date
Hello Krzysztof,

I can confirm that this also works on a Odroid-X2, so I guess it's safe
to enable the PRNG for all Exynos4412-based Odroid devices.

Any chance that you might also take a look at the other hwcrypto stuff
on the SoC ('samsung,exynos4210-secss' compatible)?

With best wishes,
Tobias
