Subject: [PATCH] OMAP3: PM: Update voltage levels for OPP1/2 on VDD1/2
Date: Fri, 13 Feb 2009 11:30:57 +0530	[thread overview]
Message-ID: <5A47E75E594F054BAF48C5E4FC4B92AB02F55511F7@dbde02.ent.ti.com> (raw)

This patch updates the voltage levels for VDD1 OPP1/2 and
VDD2 OPP1/2 according to the latest operating condition
addendum for 3430.

The new voltage levels at various OPP's for VDD1/2 are as below

VDD1 OPP1 0.975v
VDD1 OPP2 1.050v
VDD1 OPP3 1.200v
VDD1 OPP4 1.270v
VDD1 OPP5 1.350v

VDD2 OPP1 0.975v
VDD2 OPP2 1.050v
VDD2 OPP3 1.150v

The patch applies on the latest pm head and is validated on 3430SDP.
