From 997ad2900ac13b8afcfc45ce79bf662551a501eb Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Thu, 4 Jul 2013 11:26:03 +0530 Subject: crypto: caam - RNG instantiation by directly programming DECO Remove the dependency of RNG instantiation on Job Ring. Now RNG instantiation for devices with RNG version > 4 is done by directly programming DECO 0.
