Subject: [PATCH 6/6] ARM: dts: am437x-gp-evm: Add sleep state for beeper pins
Date: Wed, 7 Nov 2018 10:34:20 +0530 [thread overview]
Message-ID: <1541567060-5671-7-git-send-email-j-keerthy@ti.com> (raw)
In-Reply-To: <1541567060-5671-1-git-send-email-j-keerthy@ti.com>
Add sleep state for beeper pins. Without this there was a power
increase during the suspend and standby states on V3_3D domain.
Signed-off-by: Keerthy <j-keerthy@ti.com>
