+Qualcomm ADSP Peripheral Image Loader
+
+This document defines the binding for a component that loads and boots firmware
+on the Qualcomm ADSP core.
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be one of:
+ "qcom,adsp-pil"
+
+- interrupts-extended:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: must list the watchdog, fatal IRQs ready, handover and
+ stop-ack IRQs
+
+- interrupt-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "wdog", "fatal", "ready", "handover", "stop-ack"
+
+- cx-supply:
+ Usage: required
+ Value type: <phandle>
+ Definition: reference to the regulator to be held on behalf of the
+ booting of the Hexagon core
+
+- memory-region:
+ Usage: required
+ Value type: <phandle>
+ Definition: reference to the reserved-memory for the ADSP
+
+- qcom,smem-states:
+ Usage: required
+ Value type: <phandle>
+ Definition: reference to the smem state for requesting the ADSP to
+ shut down
+
+- qcom,smem-state-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "stop"
+
+= EXAMPLE
+The following example describes the resources needed to boot control the
+ADSP, as it is found on MSM8974 boards.
+
+ adsp {
+ compatible = "qcom,adsp-pil";
+
+ interrupts-extended = <&intc 0 162 1>,
+ <&adsp_smp2p_in 0 0>,
+ <&adsp_smp2p_in 1 0>,
+ <&adsp_smp2p_in 2 0>,
+ <&adsp_smp2p_in 3 0>;
+ interrupt-names = "wdog",
+ "fatal",
+ "ready",
+ "handover",
+ "stop-ack";
+
+ cx-supply = <&pm8841_s2>;
+
+ memory-region = <&adsp_region>;
+
+ qcom,smem-states = <&adsp_smp2p_out 0>;
+ qcom,smem-state-names = "stop";
+ };
