-+Introduction
-+------------
-+
-+A DPAA2 DPIO (Data Path I/O) is a hardware object that provides
-+interfaces to enqueue and dequeue frames to/from network interfaces
-+and other accelerators. A DPIO also provides hardware buffer
-+pool management for network interfaces.
-+
-+This document provides an overview the Linux DPIO driver, its
-+subcomponents, and its APIs.
-+
-+See Documentation/dpaa2/overview.txt for a general overview of DPAA2
-+and the general DPAA2 driver architecture in Linux.
-+
-+Driver Overview
-+---------------
-+
-+The DPIO driver is bound to DPIO objects discovered on the fsl-mc bus and
-+provides services that:
-+ A) allow other drivers, such as the Ethernet driver, to enqueue and dequeue
-+ frames for their respective objects
-+ B) allow drivers to register callbacks for data availability notifications
-+ when data becomes available on a queue or channel
-+ C) allow drivers to manage hardware buffer pools
-+
-+The Linux DPIO driver consists of 3 primary components--
-+ DPIO object driver-- fsl-mc driver that manages the DPIO object
-+ DPIO service-- provides APIs to other Linux drivers for services
-+ QBman portal interface-- sends portal commands, gets responses
-+
-+ fsl-mc other
-+ bus drivers

-+
-+
-+DPIO Object Driver (dpio-driver.c)
-+----------------------------------
-+
-+ The dpio-driver component registers with the fsl-mc bus to handle objects of
-+ type "dpio". The implementation of probe() handles basic initialization
-+ of the DPIO including mapping of the DPIO regions (the QBman SW portal)
-+ and initializing interrupts and registering irq handlers. The dpio-driver
-+ registers the probed DPIO with dpio-service.
-+
-+DPIO service (dpio-service.c, dpaa2-io.h)
-+------------------------------------------
-+
-+ The dpio service component provides queuing, notification, and buffers
-+ management services to DPAA2 drivers, such as the Ethernet driver. A system
-+ will typically allocate 1 DPIO object per CPU to allow queuing operations
-+ to happen simultaneously across all CPUs.
-+
-+ Notification handling
-+ dpaa2_io_service_register()
-+ dpaa2_io_service_deregister()
-+ dpaa2_io_service_rearm()
-+
-+ Queuing
-+ dpaa2_io_service_pull_fq()
-+ dpaa2_io_service_pull_channel()
-+ dpaa2_io_service_enqueue_fq()
-+ dpaa2_io_service_enqueue_qd()
-+ dpaa2_io_store_create()
-+ dpaa2_io_store_destroy()
-+ dpaa2_io_store_next()
-+
-+ Buffer pool management
-+ dpaa2_io_service_release()
-+ dpaa2_io_service_acquire()
-+
-+QBman portal interface (qbman-portal.c)
-+---------------------------------------
-+
-+ The qbman-portal component provides APIs to do the low level hardware
-+ bit twiddling for operations such as:
-+ -initializing Qman software portals
-+ -building and sending portal commands
-+ -portal interrupt configuration and processing
-+
-+ The qbman-portal APIs are not public to other drivers, and are
-+ only used by dpio-service.
-+
-+Other (dpaa2-fd.h, dpaa2-global.h)
-+----------------------------------
-+
-+ Frame descriptor and scatter-gather definitions and the APIs used to
-+ manipulate them are defined in dpaa2-fd.h.
-+
-+ Dequeue result struct and parsing APIs are defined in dpaa2-global.h.
