+ *
+ * Boot-time configuration data is used to define the configuration of the
+ * IPA and GSI resources to use for a given platform.  This data is supplied
+ * via the Device Tree match table, associated with a particular compatible
+ * string.  The data defines information about resources, endpoints, and
+ * channels.
+ *
+ * Resources are data structures used internally by the IPA hardware.  The
+ * configuration data defines the number (or limits of the number) of various
+ * types of these resources.
+ *
+ * Endpoint configuration data defines properties of both IPA endpoints and
+ * GSI channels.  A channel is a GSI construct, and represents a single
+ * communication path between the IPA and a particular execution environment
+ * (EE), such as the AP or Modem.  Each EE has a set of channels associated
+ * with it, and each channel has an ID unique for that EE.  For the most part
+ * the only GSI channels of concern to this driver belong to the AP
+ *
+ * An endpoint is an IPA construct representing a single channel anywhere
+ * in the system.  An IPA endpoint ID maps directly to an (EE, channel_id)
+ * pair.  Generally, this driver is concerned with only endpoints associated
+ * with the AP, however this will change when support for routing (etc.) is
+ * added.  IPA endpoint and GSI channel configuration data are defined
+ * together, establishing the endpoint_id->(EE, channel_id) mapping.
+ *
+ * Endpoint configuration data consists of three parts:  properties that
+ * are common to IPA and GSI (EE ID, channel ID, endpoint ID, and direction);
+ * properties associated with the GSI channel; and properties associated with
+ * the IPA endpoint.
