Subject: [PATCH 4/5] OMAP4: PM: TWL6030: fix ON/RET/OFF voltages
Date: Mon, 29 Aug 2011 11:15:20 -0700 [thread overview]
Message-ID: <1314641721-5172-5-git-send-email-khilman@ti.com> (raw)
In-Reply-To: <1314641721-5172-1-git-send-email-khilman@ti.com>
From: Patrick Titiano <p-titiano@ti.com>
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.
