Subject: [RESEND PATCH 3/3] ARM: dts: am437x-sk-evm: disable DDR regulator in rtc-only/poweroff mode
Date: Thu, 11 Aug 2016 10:57:50 +0530 [thread overview]
Message-ID: <1470893270-5042-4-git-send-email-j-keerthy@ti.com> (raw)
In-Reply-To: <1470893270-5042-1-git-send-email-j-keerthy@ti.com>
From: Tero Kristo <t-kristo@ti.com>
Without this, the memory will remain active during poweroff consuming
extra power. Please note revision 2.1 PMIC seems to fail when DCDC3
disable is attempted, so this is not done on that PMIC revision. The
PMIC revision checks in the regulator patches make sure of this.
