Subject: [PATCH 10/10] arm: dts: qcom: Add idle state device nodes for 8064
Date: Wed, 26 Nov 2014 15:28:30 -0700 [thread overview]
Message-ID: <1417040910-43290-11-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 state device bindings for cpuidle support for APQ
8064.
Support Standby and Standalone power collapse (power down that does not
affect any SoC idle states) for each cpu.
