From 892451071de77a088a6227e36d3a2732d51c5b84 Mon Sep 17 00:00:00 2001 From: Naveen Krishna Chatradhi Date: Thu, 8 May 2014 21:58:14 +0800 Subject: 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 Reviewed-by: Tomasz Figa CC: David S.
