+Qualcomm Hexagon (Q6) - WCSS Peripheral Image Loader
+
+This document defines the binding for a component that loads and boots firmware
+on the integrated Qualcomm Hexagon - WCSS core.
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be one of:
+		    "qcom,q6v5-wcss-pil",
+- reg:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: must specify the base address and size of the qdsp6 and
+		    mpm (msm power manager) register blocks.
+
+- reg-names:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "q6" and "mpm"
+
+- 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"
+
+- clocks:
+	Usage: required
+	Value type: <phandle>
+	Definition: references to the axim-q6, axim2-q6, axi-wcss,
+		    ahb-q6, ahbs-q6, ahb-wcss, ahbs-wcss, sysnoc and mem.
+		    to be held on behalf of the booting of the Hexagon and WCSS
+		    core. These are the interface, bus, mem clocks required for
+		    the Q6 and WCSS cores.
+
+- clock-names:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "axim-q6", "axim2-q6", "axi-wcss", "ahb-q6",
+			    "ahbs-q6", "ahb-wcss", "ahbs-wcss", "sysnoc", "mem"
+
+- resets:
+	Usage: required
+	Value type: <phandle>
+	Definition: reference to the reset-controller for the Q6-WCSS sub-system
+
+- reset-names:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "wcss_aon_reset", "wcss_reset", "wcss_q6_reset"
+
+- qcom,smem-states:
+	Usage: required
+	Value type: <phandle>
+	Definition: reference to the smem state for requesting the Hexagon to
+		    shut down
+
+- qcom,smem-state-names:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "stop"
+
+- qcom,halt-regs:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: a phandle reference to a syscon representing TCSR followed
+		    by the three offsets within syscon for q6, wcss and tcsr global
+		    halt registers.
+
+= SUBNODES:
+The Hexagon node must contain a subnode, named "q6" representing
+the memory region used by the Hexagon firmware. The sub-node must contain:
+
+- memory-region:
+	Usage: required
+	Value type: <phandle>
+	Definition: reference to the reserved-memory for the Q6 firmware region
+
+= EXAMPLE
+The following example describes the resources needed to boot control the
+Hexagon, as it is found on IPQ8074 boards.
