Subject: [PATCH] hwrng: exynos - Enable Exynos850 support
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
