Subject: [PATCH 1/2] ARM: DTS: am437x-sk-evm: Add sleep pin settings for mcasp1
Date: Thu, 2 Jul 2015 14:58:05 +0300	[thread overview]
Message-ID: <1435838286-30491-2-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1435838286-30491-1-git-send-email-peter.ujfalusi@ti.com>

When McASP is not in use the pins can be put to sleep mode to conserve
power.
