From: Lokesh Vutla Date: Wed, 3 Jun 2015 11:27:47 +0000 (+0530) Subject: ARM: DRA7xx: EMIF: Fix DLL_CALIB_CTRL register X-Git-Tag: v2015.07-rc3~79 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ee4dc2590f00d0109bcdb282ad86fd3dce567e50;p=platform%2Fkernel%2Fu-boot.git ARM: DRA7xx: EMIF: Fix DLL_CALIB_CTRL register When DLL_CALIB_INTERVAL is set, an extra delay is added which is not required and it consumes EMIF bandwidth. So making the DLL_CALIB_CTRL[8:0]DLL_CALIB_INTERVAL bits to 0.
