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. Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> --- Changes in v2: - Changed QUIRK_SMC to EXYNOS_SMC to reflect the name change in the previous patch drivers/char/hw_random/exynos-trng.c | 3 +++ 1 file changed, 3 insertions(+)
