From 63f60a43e640c2f56be902c69503ea28d1010416 Mon Sep 17 00:00:00 2001 From: Patrick Titiano Date: Wed, 18 May 2011 00:17:33 -0500 Subject: OMAP4: PM: TWL6030: fix ON/RET/OFF voltages According to latest OMAP4430 Data Manual v0.4 dated March 2011: - Retention voltage shall be set to 0.83V. See tables 2.2, 2.4 and 2.6 in DM. This allows saving a little more power in retention states. - OPP100 IVA nominal voltage is 1.188V. See table 2.4 in DM. This allows saving a little power when CPU wakes up until Smart-Reflex is not yet resumed.
