+Qualcomm Technologies, Inc. SMSM Point-to-Point (SMP2P) Sleepstate driver
+
+Required properties:
+-compatible : should be one of the following:
+- "qcom,smp2p-sleepstate"
+-qcom,smem-states : the relevant outgoing smp2p entry
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+  this one is cascaded from
+- interrupts: specifies the interrupt number, the irq line to be used
+- interrupt-names: Interrupt name string, must be "smp2p-sleepstate-in"
+
+Example:
+qcom,smp2p_sleepstate {
+	compatible = "qcom,smp2p-sleepstate";
+	qcom,smem-states = <&sleepstate_smp2p_out 0>;
+	interrupt-parent = <&sleepstate_smp2p_in>;
+	interrupts = <0 0>;
+	interrupt-names = "smp2p-sleepstate-in";
+};
