From f266950d0234599cc6d4a5602e43d0fb782de1d2 Mon Sep 17 00:00:00 2001 From: Jouni Hogander Date: Tue, 27 Jan 2009 19:44:38 -0700 Subject: [ARM] OMAP3: PM: Emu_pwrdm is switched off by hardware even when sdti is in use Using sdti doesn't keep emu_pwrdm on if hardware supervised pwrdm transitions are used. This causes sdti stop to work when power management is initialized and hardware supervised pwrdm control is enabled. This patch disables hardware supervised pwrdm control for emu_pwrdm. Now emu_pwrdm is switched off on boot by software when it is not used.
