From c5aac958ae99bd556d077a49618e4a5daf0e65f3 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Mon, 8 Jul 2013 18:41:02 +0800 Subject: exynos5250: Correct DDR3 Phy-reset value names. The name "LPDDR3PHY_CTRL_PHY_RESET_OFF" is not appropriate because the real phy-reset is a low-active pin, so "off(0)" will trigger "start to reset". To prevent confusion, we should rename the constants to "RESET_ENABLE" and "RESET_DISABLE".
