+Qualcomm IPA (IP Accelerator) Driver
+
+This binding describes the Qualcomm IPA.  The IPA is capable of offloading
+certain network processing tasks (e.g. filtering, routing, and NAT) from
+the main processor.  The IPA currently serves only as a network interface,
+providing access to an LTE network available via a modem.
+
+The IPA sits between multiple independent "execution environments,"
+including the AP subsystem (APSS) and the modem.  The IPA presents
+a Generic Software Interface (GSI) to each execution environment.
+The GSI is an integral part of the IPA, but it is logically isolated
+and has a distinct interrupt and a separately-defined address space.

+  bindings/clock/clock-bindings.txt
+
+All properties defined below are required.
+
+- compatible:
+	Must be one of the following compatible strings:
+		"qcom,ipa-sdm845-modem_init"
+		"qcom,ipa-sdm845-tz_init"
+
+-reg:
+	Resources specyfing the physical address spaces of the IPA and GSI.
+
+-reg-names:
+	The names of the address space ranges defined by the "reg" property.
+	Must be "ipa" and "gsi".
+
+- interrupts-extended:
+	Specifies the IRQs used by the IPA.  Four cells are required,
+	specifying: the IPA IRQ; the GSI IRQ; the clock query interrupt
+	from the modem; and the "ready for stage 2 initialization"
+	interrupt from the modem.  The first two are hardware IRQs; the
+	third and fourth are SMP2P input interrupts.
+
+- interrupt-names:
+	The names of the interrupts defined by the "interrupts-extended"
+	property.  Must be "ipa", "gsi", "ipa-clock-query", and
+	"ipa-post-init".
+
+- clocks:
+	Resource that defines the IPA core clock.
+
+- clock-names:
+	The name used for the IPA core clock.  Must be "core".
+
+- interconnects:
+	Specifies the interconnects used by the IPA.  Three cells are
+	required, specifying:  the path from the IPA to memory; from
+	IPA to internal (SoC resident) memory; and between the AP
+	subsystem and IPA for register access.
+
+- interconnect-names:
+	The names of the interconnects defined by the "interconnects"
+	property.  Must be "memory", "imem", and "config".
+
+- qcom,smem-states
+	The state bits used for SMP2P output.  Two cells must be specified.
+	The first indicates whether the value in the second bit is valid
+	(1 means valid).  The second, if valid, defines whether the IPA
+	clock is enabled (1 means enabled).
+
+- qcom,smem-state-names
+	The names of the state bits used for SMP2P output.  These must be
+	"ipa-clock-enabled-valid" and "ipa-clock-enabled".
+
+- memory-region
+	A phandle for a reserved memory area that holds the firmware passed
+	to Trust Zone for authentication.  (Note, this is required
+	only for "qcom,ipa-sdm845-tz_init".)
+
+= EXAMPLE
+
+The following example represents the IPA present in the SDM845 SoC.  It
+shows portions of the "modem-smp2p" node to indicate its relationship
+with the interrupts and SMEM states used by the IPA.
