Subject: [PATCH 08/10] arm: dts: qcom: Add idle states device nodes for 8074
Date: Wed, 26 Nov 2014 15:28:28 -0700 [thread overview]
Message-ID: <1417040910-43290-9-git-send-email-lina.iyer@linaro.org> (raw)
In-Reply-To: <1417040910-43290-1-git-send-email-lina.iyer@linaro.org>
Add ARM common idle states device bindings for cpuidle support for APQ
8074/8974.
Support Standby and Standalone power collapse (power down that does not
affect any SoC idle states) for each cpu.
