Subject: [PATCH 5/9] ARM: dts: omap5-uevm: update LDO3 voltage to 1.5V and settings
Date: Wed, 17 Jul 2013 11:45:34 -0500	[thread overview]
Message-ID: <1374079538-19548-6-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1374079538-19548-1-git-send-email-nm@ti.com>

commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.

LDO3 supplies Low Latency Interface(LLI) hardware module which is a
special hardware to communicate with Modem. However since uEVM is
not setup by default for this communication, this should be disabled
by default.

Further, vdda_lli is supposed to be 1.5V and not 3V.
