From c48c89543310bae633c7aa44a0fc94b9c97c8453 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 24 Jul 2012 14:03:24 -0700 Subject: am33xx: Document what we're doing with ddrctrl->ddrckectrl - Remove the call to set ddrctrl->ddrioctrl as it's all zeros. - Comment what we're really setting in ddrctrl->ddrckectrl which is that we're operating in the normal mode where EMIF/PHY clock is controlled by the PHY.
