From 9ea03dec380208bfee015b25f253c2f58aba0071 Mon Sep 17 00:00:00 2001 From: Ambresh K Date: Sat, 16 Mar 2013 11:46:42 +0530 Subject: [PATCH] memory: emif: setup LP settings on freq update Program the power management shadow register on freq update Else the concept of threshold frequencies dont really matter as the system always uses the performance mode timing for LP which is programmed in at init time.
