Subject: [RFC] [PATCH 08/13] arm: dts: qcom: Add device binding for sleep status
Date: Thu,  7 Aug 2014 22:05:17 -0600	[thread overview]
Message-ID: <1407470722-23015-9-git-send-email-lina.iyer@linaro.org> (raw)
In-Reply-To: <1407470722-23015-1-git-send-email-lina.iyer@linaro.org>

QCOM processors get the feedback on the processor subsystem logic that
notifies when the processor has entered the low power state. This is
used for pm to gaurantee that the processor is indeed in its low
power state before the associated resources can be turned off.
