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 Krzysztof Kozlowski (3): clk: samsung: exynos4: Add SSS gate clock ARM: dts: Add PRNG module for exynos4 ARM: dts: Enable PRNG module on exynos4412-trats2 arch/arm/boot/dts/exynos4.dtsi | 8 ++++++++ arch/arm/boot/dts/exynos4412-trats2.dts | 4 ++++ drivers/clk/samsung/clk-exynos4.c | 1 + include/dt-bindings/clock/exynos4.h | 1 + 4 files changed, 14 insertions(+) -- 1.9.1
