+What is sm712fb?
+=================
+
+This is a graphics framebuffer driver for Silicon Motion SM712 based processors.
+
+How to use it?
+==============
+
+Switching modes is done using the video=sm712fb:... boot parameter.
+
+If you want, for example, enable a resolution of 1280x1024x24bpp you should
+pass to the kernel this command line: "video=sm712fb:0x31B".
+
+You should not compile-in vesafb.
+
+Currently supported video modes are:
+
+[Graphic modes]
+
+bpp | 640x480 800x600 1024x768 1280x1024
+----+--------------------------------------------
+ 8 | 0x301 0x303 0x305 0x307
+ 16 | 0x311 0x314 0x317 0x31A
+ 24 | 0x312 0x315 0x318 0x31B

+DPAA2 Overview
+--------------
+
+DPAA2 is a hardware architecture designed for high-speeed network
+packet processing. DPAA2 consists of sophisticated mechanisms for
+processing Ethernet packets, queue management, buffer management,
+autonomous L2 switching, virtual Ethernet bridging, and accelerator
+(e.g. crypto) sharing.
+
+A DPAA2 hardware component called the Management Complex (or MC) manages the
+DPAA2 hardware resources. The MC provides an object-based abstraction for
+software drivers to use the DPAA2 hardware.
+
+The MC uses DPAA2 hardware resources such as queues, buffer pools, and
+network ports to create functional objects/devices such as network
+interfaces, an L2 switch, or accelerator instances.
+
+The MC provides memory-mapped I/O command interfaces (MC portals)
+which DPAA2 software drivers use to operate on DPAA2 objects:

+ | -network interface -DPNI |
+ | profiles -DPMAC |
+ | -queue portals -DPBP |
+ | -MC portals ... |
+ | ... |
+ | |
+ +--------------------------------------+
+
+The MC mediates operations such as create, discover,
+connect, configuration, and destroy. Fast-path operations
+on data, such as packet transmit/receive, are not mediated by
+the MC and are done directly using memory mapped regions in
+DPIO objects.
+
+Overview of DPAA2 Objects
+-------------------------
+The section provides a brief overview of some key objects
+in the DPAA2 hardware. A simple scenario is described illustrating

+-DPRC (Datapath Resource Container)
+
+ A DPRC is an container object that holds all the other
+ types of DPAA2 objects. In the example diagram below there
+ are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
+ in the container.
+
+ +---------------------------------------------------------+
+ | DPRC |
+ | |
+ | +-------+ +-------+ +-------+ +-------+ +-------+ |
+ | | DPMCP | | DPIO | | DPBP | | DPNI | | DPMAC | |
+ | +-------+ +-------+ +-------+ +---+---+ +---+---+ |
+ | | DPMCP | | DPIO | |
+ | +-------+ +-------+ |
+ | | DPMCP | |
+ | +-------+ |
+ | |
+ +---------------------------------------------------------+
+
+ From the point of view of an OS, a DPRC is bus-like. Like
+ a plug-and-play bus, such as PCI, DPRC commands can be used to
+ enumerate the contents of the DPRC, discover the hardware
+ objects present (including mappable regions and interrupts).
+
+ dprc.1 (bus)
+ |
+ +--+--------+-------+-------+-------+
+ | | | | |
+ dpmcp.1 dpio.1 dpbp.1 dpni.1 dpmac.1
+ dpmcp.2 dpio.2
+ dpmcp.3
+
+ Hardware objects can be created and destroyed dynamically, providing
+ the ability to hot plug/unplug objects in and out of the DPRC.
+
+ A DPRC has a mappable mmio region (an MC portal) that can be used
+ to send MC commands. It has an interrupt for status events (like
+ hotplug).
+
+ All objects in a container share the same hardware "isolation context".
+ This means that with respect to an IOMMU the isolation granularity
+ is at the DPRC (container) level, not at the individual object
+ level.
+
+ DPRCs can be defined statically and populated with objects
+ via a config file passed to the MC when firmware starts
+ it. There is also a Linux user space tool called "restool"
+ that can be used to create/destroy containers and objects
+ dynamically.
+
+-DPAA2 Objects for an Ethernet Network Interface
+
+ A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX
+ queuing mechanisms, configuration mechanisms, buffer management,
+ physical ports, and interrupts. DPAA2 uses a more granular approach
+ utilizing multiple hardware objects. Each object has specialized
+ functions, and are used together by software to provide Ethernet network
+ interface functionality. This approach provides efficient use of finite
+ hardware resources, flexibility, and performance advantages.
+
+ The diagram below shows the objects needed for a simple
+ network interface configuration on a system with 2 CPUs.

+ port/PHY
+
+ Below the objects are described. For each object a brief description
+ is provided along with a summary of the kinds of operations the object
+ supports and a summary of key resources of the object (mmio regions
+ and irqs).
+
+ -DPMAC (Datapath Ethernet MAC): represents an Ethernet MAC, a
+ hardware device that connects to an Ethernet PHY and allows
+ physical transmission and reception of Ethernet frames.
+ -mmio regions: none
+ -irqs: dpni link change
+ -commands: set link up/down, link config, get stats,
+ irq config, enable, reset
+
+ -DPNI (Datapath Network Interface): contains TX/RX queues,
+ network interface configuration, and rx buffer pool configuration
+ mechanisms.
+ -mmio regions: none
+ -irqs: link state
+ -commands: port config, offload config, queue config,
+ parse/classify config, irq config, enable, reset
+
+ -DPIO (Datapath I/O): provides interfaces to enqueue and dequeue
+ packets and do hardware buffer pool management operations. For
+ optimum performance there is typically DPIO per CPU. This allows
+ each CPU to perform simultaneous enqueue/dequeue operations.
+ -mmio regions: queue operations, buffer mgmt
+ -irqs: data availability, congestion notification, buffer
+ pool depletion
+ -commands: irq config, enable, reset
+
+ -DPBP (Datapath Buffer Pool): represents a hardware buffer
+ pool.
+ -mmio regions: none
+ -irqs: none
+ -commands: enable, reset
+
+ -DPMCP (Datapath MC Portal): provides an MC command portal.
+ Used by drivers to send commands to the MC to manage
+ objects.
+ -mmio regions: MC command portal
+ -irqs: command completion
+ -commands: irq config, enable, reset
+
+ Object Connections
+ ------------------
+ Some objects have explicit relationships that must
+ be configured:
+
+ -DPNI <--> DPMAC
+ -DPNI <--> DPNI
+ -DPNI <--> L2-switch-port
+ A DPNI must be connected to something such as a DPMAC,
+ another DPNI, or L2 switch port. The DPNI connection
+ is made via a DPRC command.
+
+ +-------+ +-------+
+ | DPNI | | DPMAC |
+ +---+---+ +---+---+
+ | |
+ +==========+
+
+ -DPNI <--> DPBP
+ A network interface requires a 'buffer pool' (DPBP
+ object) which provides a list of pointers to memory
+ where received Ethernet data is to be copied. The
+ Ethernet driver configures the DPBPs associated with
+ the network interface.
+
+ Interrupts
+ ----------
+ All interrupts generated by DPAA2 objects are message
+ interrupts. At the hardware level message interrupts
+ generated by devices will normally have 3 components--
+ 1) a non-spoofable 'device-id' expressed on the hardware
+ bus, 2) an address, 3) a data value.
+
+ In the case of DPAA2 devices/objects, all objects in the
+ same container/DPRC share the same 'device-id'.
+ For ARM-based SoC this is the same as the stream ID.
+
+
+DPAA2 Linux Driver Overview
+---------------------------
+
+This section provides an overview of the Linux kernel drivers for
+DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure"
+drivers and 2) functional object drivers (such as Ethernet).
+
+As described previously, a DPRC is a container that holds the other
+types of DPAA2 objects. It is functionally similar to a plug-and-play
+bus controller.
+
+Each object in the DPRC is a Linux "device" and is bound to a driver.
+The diagram below shows the Linux drivers involved in a networking
+scenario and the objects bound to each driver. A brief description
+of each driver follows.
+

+ | |
+ DPNI---DPBP |
+ | |
+ DPMAC |
+ | |
+ PHY ---------------+
+ ===================================================|========================
+
+A brief description of each driver is provided below.
+
+ mc-bus driver
+ -------------
+ The mc-bus driver is a platform driver and is probed from an
+ "/fsl-mc@xxxx" node in the device tree passed in by boot firmware.
+ It is responsible for bootstrapping the DPAA2 kernel infrastructure.
+ Key functions include:
+ -registering a new bus type named "fsl-mc" with the kernel,
+ and implementing bus call-backs (e.g. match/uevent/dev_groups)
+ -implemeting APIs for DPAA2 driver registration and for device
+ add/remove
+ -creates an MSI irq domain
+ -do a device add of the 'root' DPRC device, which is needed
+ to bootstrap things
+
+ DPRC driver
+ -----------
+ The dprc-driver is bound DPRC objects and does runtime management
+ of a bus instance. It performs the initial bus scan of the DPRC
+ and handles interrupts for container events such as hot plug.
+
+ Allocator
+ ----------
+ Certain objects such as DPMCP and DPBP are generic and fungible,
+ and are intended to be used by other drivers. For example,
+ the DPAA2 Ethernet driver needs:
+ -DPMCPs to send MC commands, to configure network interfaces
+ -DPBPs for network buffer pools
+
+ The allocator driver registers for these allocatable object types
+ and those objects are bound to the allocator when the bus is probed.
+ The allocator maintains a pool of objects that are available for
+ allocation by other DPAA2 drivers.
+
+ DPIO driver
+ -----------
+ The DPIO driver is bound to DPIO objects and provides services that allow
+ other drivers such as the Ethernet driver to receive and transmit data.
+ Key services include:
+ -data availability notifications
+ -hardware queuing operations (enqueue and dequeue of data)
+ -hardware buffer pool management
+
+ There is typically one DPIO object per physical CPU for optimum
+ performance, allowing each CPU to simultaneously enqueue
+ and dequeue data.
+
+ The DPIO driver operates on behalf of all DPAA2 drivers
+ active in the kernel-- Ethernet, crypto, compression,
+ etc.
+
+ Ethernet
+ --------
+ The Ethernet driver is bound to a DPNI and implements the kernel
+ interfaces needed to connect the DPAA2 network interface to
+ the network stack.
+
+ Each DPNI corresponds to a Linux network interface.
+
+ MAC driver
+ ----------
+ An Ethernet PHY is an off-chip, board specific component and is managed
+ by the appropriate PHY driver via an mdio bus. The MAC driver
+ plays a role of being a proxy between the PHY driver and the
+ MC. It does this proxy via the MC commands to a DPMAC object.

+ Section 1 Overview
+
+The Media Oriented Systems Transport (MOST) driver gives Linux applications
+access a MOST network: The Automotive Information Backbone and the de-facto
+standard for high-bandwidth automotive multimedia networking.
+
+MOST defines the protocol, hardware and software layers necessary to allow
+for the efficient and low-cost transport of control, real-time and packet
+data using a single medium (physical layer). Media currently in use are
+fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST
+also supports various speed grades up to 150 Mbps.
+For more information on MOST, visit the MOST Cooperation website:
+www.mostcooperation.com.
+
+Cars continue to evolve into sophisticated consumer electronics platforms,
+increasing the demand for reliable and simple solutions to support audio,
+video and data communications. MOST can be used to connect multiple
+consumer devices via optical or electrical physical layers directly to one
+another or in a network configuration. As a synchronous network, MOST
+provides excellent Quality of Service and seamless connectivity for
+audio/video streaming. Therefore, the driver perfectly fits to the mission
+of Automotive Grade Linux to create open source software solutions for
+automotive applications.
+
+The driver consists basically of three layers. The hardware layer, the
+core layer and the application layer. The core layer consists of the core
+module only. This module handles the communication flow through all three
+layers, the configuration of the driver, the configuration interface
+representation in sysfs, and the buffer management.
+For each of the other two layers a selection of modules is provided. These
+modules can arbitrarily be combined to meet the needs of the desired
+system architecture. A module of the hardware layer is referred to as an
+HDM (hardware dependent module). Each module of this layer handles exactly
+one of the peripheral interfaces of a network interface controller (e.g.
+USB, MediaLB, I2C). A module of the application layer is referred to as an
+AIM (application interfacing module). The modules of this layer give access
+to MOST via one the following ways: character devices, ALSA, Networking or
+V4L2.
+
+To physically access MOST, an Intelligent Network Interface Controller
+(INIC) is needed. For more information on available controllers visit:
+www.microchip.com
+
+
+
+ Section 1.1 Hardware Layer
+
+The hardware layer contains so called hardware dependent modules (HDM). For each
+peripheral interface the hardware supports the driver has a suitable module
+that handles the interface.
+
+The HDMs encapsulate the peripheral interface specific knowledge of the driver
+and provides an easy way of extending the number of supported interfaces.
+Currently the following HDMs are available:
+
+ 1) MediaLB (DIM2)
+ Host wants to communicate with hardware via MediaLB.
+
+ 2) I2C
+ Host wants to communicate with the hardware via I2C.
+
+ 3) USB
+ Host wants to communicate with the hardware via USB.
+
+
+ Section 1.2 Core Layer
+
+The core layer contains the mostcore module only, which processes the driver
+configuration via sysfs, buffer management and data forwarding.
+
+
+
+ Section 1.2 Application Layer
+
+The application layer contains so called application interfacing modules (AIM).
+Depending on how the driver should interface to the application, one or more
+suitable modules can be selected.
+
+The AIMs encapsulate the application interface specific knowledge of the driver
+and provides access to user space or other kernel subsystems.
+Currently the following AIMs are available
+
+ 1) Character Device
+ Applications can access the driver by means of character devices.
+
+ 2) Networking
+ Standard networking applications (e.g. iperf) can by used to access
+ the driver via the networking subsystem.
+
+ 3) Video4Linux (v4l2)
+ Standard video applications (e.g. VLC) can by used to access the
+ driver via the V4L subsystem.
+
+ 4) Advanced Linux Sound Architecture (ALSA)
+ Standard sound applications (e.g. aplay, arecord, audacity) can by
+ used to access the driver via the ALSA subsystem.
+
+
+
+ Section 2 Configuration
+
+See ABI/sysfs-class-most.txt
+
+
+
+ Section 3 USB Padding
+
+When transceiving synchronous or isochronous data, the number of packets per USB
+transaction and the sub-buffer size need to be configured. These values
+are needed for the driver to process buffer padding, as expected by hardware,
+which is for performance optimization purposes of the USB transmission.
+
+When transmitting synchronous data the allocated channel width needs to be
+written to 'set_subbuffer_size'. Additionally, the number of MOST frames that
+should travel to the host within one USB transaction need to be written to
+'packets_per_xact'.
+
+Internally the synchronous threshold is calculated as follows:
+
+ frame_size = set_subbuffer_size * packets_per_xact
+
+In case 'packets_per_xact' is set to 0xFF the maximum number of packets,
+allocated within one MOST frame, is calculated that fit into _one_ 512 byte
+USB full packet.
+
+ frame_size = floor(MTU_USB / bandwidth_sync) * bandwidth_sync
+
+This frame_size is the number of synchronous data within an USB transaction,
+which renders MTU_USB - frame_size bytes for padding.
+
+When transmitting isochronous AVP data the desired packet size needs to be
+written to 'set_subbuffer_size' and hardware will always expect two isochronous
+packets within one USB transaction. This renders
+
+ MTU_USB - (2 * set_subbuffer_size)
+
+bytes for padding.
+
+Note that at least 2 times set_subbuffer_size bytes for isochronous data or
+set_subbuffer_size times packts_per_xact bytes for synchronous data need to be
+put in the transmission buffer and passed to the driver.
+
+Since HDMs are allowed to change a chosen configuration to best fit its
+constraints, it is recommended to always double check the configuration and read
+back the previously written files.
+
+
+
+ Section 4 Routing Channels
+
+To connect a channel that has been configured as outlined above to an AIM and
+make it accessible to user space applications, the attribute file 'add_link' is
+used. To actually bind a channel to the AIM a string needs to be written to the
+file that complies with the following syntax:
+
+ "most_device:channel_name:link_name[.param]"
+
+The example above links the channel "channel_name" of the device "most_device"
+to the AIM. In case the AIM interfaces the VFS this would also create a device
+node "link_name" in the /dev directory. The parameter "param" is an AIM dependent
+string, which can be omitted in case the used AIM does not make any use of it.
+
+Cdev AIM example:
+ $ echo "mdev0:ep_81:my_rx_channel" >add_link
+ $ echo "mdev0:ep_81" >add_link
+
+
+Sound/ALSA AIM example:
+
+The sound/ALSA AIM needs an additional parameter to determine the audio resolution
+that is going to be used. The following strings can be used:
+
+ - "1x8" (Mono)
+ - "2x16" (16-bit stereo)
+ - "2x24" (24-bit stereo)
+ - "2x32" (32-bit stereo)
+
+ $ echo "mdev0:ep_81:audio_rx.2x16" >add_link
+ $ echo "mdev0:ep_81" >add_link

+ *
+ * USB device drivers may only test urb status values in completion handlers.

+ *
+ * A transfer's actual_length may be positive even when an error has been
+ * reported. That's because transfers often involve several packets, so that
+ * one or more packets could finish before an error stops further endpoint I/O.
+ *
+ * For isochronous URBs, the urb status value is non-zero only if the URB is
+ * unlinked, the device is removed, the host controller is disabled or the total
+ * transferred length is less than the requested length and the URB_SHORT_NOT_OK
+ * flag is set. Completion handlers for isochronous URBs should only see
+ * urb->status set to zero, -ENOENT, -ECONNRESET, -ESHUTDOWN, or -EREMOTEIO.
+ * Individual frame descriptor status fields may report more status codes.
+ *
+ *
+ * 0 Transfer completed successfully
+ *
+ * -ENOENT URB was synchronously unlinked by usb_unlink_urb
+ *
+ * -EINPROGRESS URB still pending, no results yet
+ * (That is, if drivers see this it's a bug.)
+ *
+ * -EPROTO (*, **) a) bitstuff error
+ * b) no response packet received within the
+ * prescribed bus turn-around time
+ * c) unknown USB error
+ *
+ * -EILSEQ (*, **) a) CRC mismatch
+ * b) no response packet received within the
+ * prescribed bus turn-around time
+ * c) unknown USB error
+ *
+ * Note that often the controller hardware does not
+ * distinguish among cases a), b), and c), so a
+ * driver cannot tell whether there was a protocol
+ * error, a failure to respond (often caused by
+ * device disconnect), or some other fault.
+ *
+ * -ETIME (**) No response packet received within the prescribed
+ * bus turn-around time. This error may instead be
+ * reported as -EPROTO or -EILSEQ.
+ *
+ * -ETIMEDOUT Synchronous USB message functions use this code
+ * to indicate timeout expired before the transfer
+ * completed, and no other error was reported by HC.
+ *
+ * -EPIPE (**) Endpoint stalled. For non-control endpoints,
+ * reset this status with usb_clear_halt().
+ *
+ * -ECOMM During an IN transfer, the host controller
+ * received data from an endpoint faster than it
+ * could be written to system memory
+ *
+ * -ENOSR During an OUT transfer, the host controller
+ * could not retrieve data from system memory fast
+ * enough to keep up with the USB data rate
+ *
+ * -EOVERFLOW (*) The amount of data returned by the endpoint was
+ * greater than either the max packet size of the
+ * endpoint or the remaining buffer size. "Babble".
+ *
+ * -EREMOTEIO The data read from the endpoint did not fill the
+ * specified buffer, and URB_SHORT_NOT_OK was set in
+ * urb->transfer_flags.
+ *
+ * -ENODEV Device was removed. Often preceded by a burst of
+ * other errors, since the hub driver doesn't detect
+ * device removal events immediately.
+ *
+ * -EXDEV ISO transfer only partially completed
+ * (only set in iso_frame_desc[n].status, not urb->status)
+ *
+ * -EINVAL ISO madness, if this happens: Log off and go home
+ *
+ * -ECONNRESET URB was asynchronously unlinked by usb_unlink_urb
+ *
+ * -ESHUTDOWN The device or host controller has been disabled due
+ * to some problem that could not be worked around,
+ * such as a physical disconnect.
+ *
+ *
+ * (*) Error codes like -EPROTO, -EILSEQ and -EOVERFLOW normally indicate
+ * hardware problems such as bad devices (including firmware) or cables.
+ *
+ * (**) This is also one of several codes that different kinds of host
+ * controller use to indicate a transfer has failed because of device
