X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b0c2036df8868b97176f9a97b777846620c9a74d;p=users%2Fjedix%2Flinux-maple.git

hwrng: exynos - Enable Exynos850 support

Add Exynos850 compatible and its driver data. It's only possible to
access TRNG block via SMC calls in Exynos850, so specify that fact using
EXYNOS_SMC flag in the driver data.
