From mboxrd@z Thu Jan 1 00:00:00 1970 From: lina.iyer@linaro.org (Lina Iyer) Date: Fri, 26 Sep 2014 18:58:11 -0600 Subject: [PATCH v7 3/7] arm: dts: qcom: Add SPM device bindings for 8084 In-Reply-To: <1411779495-39724-1-git-send-email-lina.iyer@linaro.org> References: <1411779495-39724-1-git-send-email-lina.iyer@linaro.org> Message-ID: <1411779495-39724-4-git-send-email-lina.iyer@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add SPM device bindings for QCOM 8084 based cpus. SPM is the sub-system power manager and controls the logic around the cores (cpu and L2). Each core has an instance of SPM and controls only that core. Each cpu SPM is configured to support WFI and SPC (standalone-power collapse).
