crypto: s5p-sss - Add support for SSS module on Exynos
This patch adds new compatible and variant struct to support the SSS module on Exynos4 (Exynos4210), Exynos5 (Exynos5420 and Exynos5250) for which 1. AES register are at an offset of 0x200 and 2. hash interrupt is not available Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Reviewed-by: Tomasz Figa <t.figa@samsung.com> CC: David S.
