+				Theory of Operation
+
+I. Board Compatibility
+
+This driver is designed for the Sundance Technologies "Alta" ST201 chip.
+
+II. Board-specific settings
+
+III. Driver operation
+
+IIIa. Ring buffers
+
+This driver uses two statically allocated fixed-size descriptor lists
+formed into rings by a branch from the final descriptor to the beginning of
+the list.  The ring sizes are set at compile time by RX/TX_RING_SIZE.
+Some chips explicitly use only 2^N sized rings, while others use a
+'next descriptor' pointer that the driver forms into rings.
+
+IIIb/c. Transmit/Receive Structure
+
+This driver uses a zero-copy receive and transmit scheme.
+The driver allocates full frame size skbuffs for the Rx ring buffers at
+open() time and passes the skb->data field to the chip as receive data
+buffers.  When an incoming frame is less than RX_COPYBREAK bytes long,
+a fresh skbuff is allocated and the frame is copied to the new skbuff.
+When the incoming frame is larger, the skbuff is passed directly up the
+protocol stack.  Buffers consumed this way are replaced by newly allocated
+skbuffs in a later phase of receives.
+
+The RX_COPYBREAK value is chosen to trade-off the memory wasted by
+using a full-sized skbuff for small frames vs. the copying costs of larger
+frames.  New boards are typically used in generously configured machines
+and the underfilled buffers have negligible impact compared to the benefit of
+a single allocation size, so the default value of zero results in never
+copying packets.  When copying is done, the cost is usually mitigated by using
+a combined copy/checksum routine.  Copying also preloads the cache, which is
+most useful with small frames.
+
+A subtle aspect of the operation is that the IP header at offset 14 in an
+ethernet frame isn't longword aligned for further processing.
+Unaligned buffers are permitted by the Sundance hardware, so
+frames are received into the skbuff at an offset of "+2", 16-byte aligning
+the IP header.
+
+IIId. Synchronization
+
+The driver runs as two independent, single-threaded flows of control.  One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag.  The other thread is the interrupt handler, which is single
+threaded by the hardware and interrupt handling software.
+
+The send packet thread has partial control over the Tx ring and 'dev->tbusy'
+flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next
+queue slot is empty, it clears the tbusy flag when finished otherwise it sets
+the 'lp->tx_full' flag.
+
+The interrupt handler has exclusive control over the Rx ring and records stats
+from the Tx ring.  After reaping the stats, it marks the Tx queue entry as
+empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it
+clears both the tx_full and tbusy flags.

 pub mod property;
 
-/// A reference-counted device.
+/// The core representation of a device in the kernel's driver model.
 ///
-/// This structure represents the Rust abstraction for a C `struct device`. This implementation
-/// abstracts the usage of an already existing C `struct device` within Rust code that we get
-/// passed from the C side.
+/// This structure represents the Rust abstraction for a C `struct device`. A [`Device`] can either
+/// exist as temporary reference (see also [`Device::from_raw`]), which is only valid within a
+/// certain scope or as [`ARef<Device>`], owning a dedicated reference count.
 ///
-/// An instance of this abstraction can be obtained temporarily or permanent.
+/// # Device Types
 ///
-/// A temporary one is bound to the lifetime of the C `struct device` pointer used for creation.
-/// A permanent instance is always reference-counted and hence not restricted by any lifetime
-/// boundaries.
+/// A [`Device`] can represent either a bus device or a class device.
 ///
-/// For subsystems it is recommended to create a permanent instance to wrap into a subsystem
-/// specific device structure (e.g. `pci::Device`). This is useful for passing it to drivers in
-/// `T::probe()`, such that a driver can store the `ARef<Device>` (equivalent to storing a
-/// `struct device` pointer in a C driver) for arbitrary purposes, e.g. allocating DMA coherent
-/// memory.
+/// ## Bus Devices
+///
+/// A bus device is a [`Device`] that is associated with a physical or virtual bus. Examples of
+/// buses include PCI, USB, I2C, and SPI. Devices attached to a bus are registered with a specific
+/// bus type, which facilitates matching devices with appropriate drivers based on IDs or other
+/// identifying information. Bus devices are visible in sysfs under `/sys/bus/<bus-name>/devices/`.
+///
+/// ## Class Devices
+///
+/// A class device is a [`Device`] that is associated with a logical category of functionality
+/// rather than a physical bus. Examples of classes include block devices, network interfaces, sound
+/// cards, and input devices. Class devices are grouped under a common class and exposed to
+/// userspace via entries in `/sys/class/<class-name>/`.
+///
+/// # Device Context
+///
+/// [`Device`] references are generic over a [`DeviceContext`], which represents the type state of
+/// a [`Device`].
+///
+/// As the name indicates, this type state represents the context of the scope the [`Device`]
+/// reference is valid in. For instance, the [`Bound`] context guarantees that the [`Device`] is
+/// bound to a driver for the entire duration of the existence of a [`Device<Bound>`] reference.
+///
+/// Other [`DeviceContext`] types besides [`Bound`] are [`Normal`], [`Core`] and [`CoreInternal`].
+///
+/// Unless selected otherwise [`Device`] defaults to the [`Normal`] [`DeviceContext`], which by
+/// itself has no additional requirements.
+///
+/// It is always up to the caller of [`Device::from_raw`] to select the correct [`DeviceContext`]
+/// type for the corresponding scope the [`Device`] reference is created in.
+///
+/// All [`DeviceContext`] types other than [`Normal`] are intended to be used with
+/// [bus devices](#bus-devices) only.
+///
+/// # Implementing Bus Devices
+///
+/// This section provides a guideline to implement bus specific devices, such as [`pci::Device`] or
+/// [`platform::Device`].
+///
+/// A bus specific device should be defined as follows.
+///
+/// ```ignore
+/// #[repr(transparent)]
+/// pub struct Device<Ctx: device::DeviceContext = device::Normal>(
+///     Opaque<bindings::bus_device_type>,
+///     PhantomData<Ctx>,
+/// );
+/// ```
+///
+/// Since devices are reference counted, [`AlwaysRefCounted`] should be implemented for `Device`
+/// (i.e. `Device<Normal>`). Note that [`AlwaysRefCounted`] must not be implemented for any other
+/// [`DeviceContext`], since all other device context types are only valid within a certain scope.
+///
+/// In order to be able to implement the [`DeviceContext`] dereference hierarchy, bus device
+/// implementations should call the [`impl_device_context_deref`] macro as shown below.
+///
+/// ```ignore
+/// // SAFETY: `Device` is a transparent wrapper of a type that doesn't depend on `Device`'s
+/// // generic argument.
+/// kernel::impl_device_context_deref!(unsafe { Device });
+/// ```
+///
+/// In order to convert from a any [`Device<Ctx>`] to [`ARef<Device>`], bus devices can implement
+/// the following macro call.
+///
+/// ```ignore
+/// kernel::impl_device_context_into_aref!(Device);
+/// ```
+///
+/// Bus devices should also implement the following [`AsRef`] implementation, such that users can
+/// easily derive a generic [`Device`] reference.
+///
+/// ```ignore
+/// impl<Ctx: device::DeviceContext> AsRef<device::Device<Ctx>> for Device<Ctx> {
+///     fn as_ref(&self) -> &device::Device<Ctx> {
+///         ...
+///     }
+/// }
+/// ```
+///
+/// # Implementing Class Devices
+///
+/// Class device implementations require less infrastructure and depend slightly more on the
+/// specific subsystem.
+///
+/// An example implementation for a class device could look like this.
+///
+/// ```ignore
+/// #[repr(C)]
+/// pub struct Device<T: class::Driver> {
+///     dev: Opaque<bindings::class_device_type>,
+///     data: T::Data,
+/// }

 //! Generic support for drivers of different buses (e.g., PCI, Platform, Amba, etc.).
 //!
-//! Each bus / subsystem is expected to implement [`RegistrationOps`], which allows drivers to
-//! register using the [`Registration`] class.
+//! This documentation describes how to implement a bus specific driver API and how to align it with
+//! the design of (bus specific) devices.
+//!
+//! Note: Readers are expected to know the content of the documentation of [`Device`] and
+//! [`DeviceContext`].
+//!
+//! # Driver Trait
+//!
+//! The main driver interface is defined by a bus specific driver trait. For instance:
+//!
+//! ```ignore
+//! pub trait Driver: Send {
+//!     /// The type holding information about each device ID supported by the driver.
+//!     type IdInfo: 'static;
+//!
+//!     /// The table of OF device ids supported by the driver.
+//!     const OF_ID_TABLE: Option<of::IdTable<Self::IdInfo>> = None;
+//!
+//!     /// The table of ACPI device ids supported by the driver.
+//!     const ACPI_ID_TABLE: Option<acpi::IdTable<Self::IdInfo>> = None;
+//!
+//!     /// Driver probe.
+//!     fn probe(dev: &Device<device::Core>, id_info: &Self::IdInfo) -> Result<Pin<KBox<Self>>>;
+//!
+//!     /// Driver unbind (optional).
+//!     fn unbind(dev: &Device<device::Core>, this: Pin<&Self>) {
+//!         let _ = (dev, this);
+//!     }
+//! }
+//! ```
+//!
+//! For specific examples see [`auxiliary::Driver`], [`pci::Driver`] and [`platform::Driver`].
+//!
+//! The `probe()` callback should return a `Result<Pin<KBox<Self>>>`, i.e. the driver's private
+//! data. The bus abstraction should store the pointer in the corresponding bus device. The generic
+//! [`Device`] infrastructure provides common helpers for this purpose on its
+//! [`Device<CoreInternal>`] implementation.
+//!
+//! All driver callbacks should provide a reference to the driver's private data. Once the driver
+//! is unbound from the device, the bus abstraction should take back the ownership of the driver's
+//! private data from the corresponding [`Device`] and [`drop`] it.
+//!
+//! All driver callbacks should provide a [`Device<Core>`] reference (see also [`device::Core`]).
+//!
+//! # Adapter
+//!
+//! The adapter implementation of a bus represents the abstraction layer between the C bus
+//! callbacks and the Rust bus callbacks. It therefore has to be generic over an implementation of
+//! the [driver trait](#driver-trait).
+//!
+//! ```ignore
+//! pub struct Adapter<T: Driver>;
+//! ```
+//!
+//! There's a common [`Adapter`] trait that can be implemented to inherit common driver
+//! infrastructure, such as finding the ID info from an [`of::IdTable`] or [`acpi::IdTable`].
+//!
+//! # Driver Registration
+//!
+//! In order to register C driver types (such as `struct platform_driver`) the [adapter](#adapter)
+//! should implement the [`RegistrationOps`] trait.
+//!
+//! This trait implementation can be used to create the actual registration with the common
+//! [`Registration`] type.
+//!
+//! Typically, bus abstractions want to provide a bus specific `module_bus_driver!` macro, which
+//! creates a kernel module with exactly one [`Registration`] for the bus specific adapter.
+//!
+//! The generic driver infrastructure provides a helper for this with the [`module_driver`] macro.
+//!
+//! # Device IDs
+//!
+//! Besides the common device ID types, such as [`of::DeviceId`] and [`acpi::DeviceId`], most buses
+//! may need to implement their own device ID types.
+//!
+//! For this purpose the generic infrastructure in [`device_id`] should be used.
