Subject: [PATCH v10 08/10] arm: dts: qcom: Add idle states device nodes for 8074
Date: Fri, 21 Nov 2014 11:03:55 -0700 [thread overview]
Message-ID: <1416593037-27527-9-git-send-email-lina.iyer@linaro.org> (raw)
In-Reply-To: <1416593037-27527-1-git-send-email-lina.iyer-QSEj5FYQhm4dnm+yROfE0A@public.gmane.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.
