Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner.
The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded
cx23416 hardware MPEG2 encoder. There are two major variants of this
device; this driver handles both. Any V4L2 application which
understands MPEG2 video stream data should be able to work with this
device.

+ pvrusb2 driver
+
+Background:
+
+ This driver is intended for the "Hauppauge WinTV PVR USB 2.0", which
+ is a USB 2.0 hosted TV Tuner. This driver is a work in progress.
+ Its history started with the reverse-engineering effort by Björn
+ Danielsson <pvrusb2@dax.nu> whose web page can be found here:
+
+ http://pvrusb2.dax.nu/
+
+ From there Aurelien Alleaume <slts@free.fr> began an effort to
+ create a video4linux compatible driver. I began with Aurelien's
+ last known snapshot and evolved the driver to the state it is in
+ here.
+
+ More information on this driver can be found at:
+
+ http://www.isely.net/pvrusb2.html
+
+
+ This driver has a strong separation of layers. They are very
+ roughly:
+
+ 1a. Low level wire-protocol implementation with the device.
+
+ 1b. I2C adaptor implementation and corresponding I2C client drivers
+ implemented elsewhere in V4L.
+
+ 1c. High level hardware driver implementation which coordinates all
+ activities that ensure correct operation of the device.
+
+ 2. A "context" layer which manages instancing of driver, setup,
+ tear-down, arbitration, and interaction with high level
+ interfaces appropriately as devices are hotplugged in the
+ system.
+
+ 3. High level interfaces which glue the driver to various published
+ Linux APIs (V4L, sysfs, maybe DVB in the future).
+
+ The most important shearing layer is between the top 2 layers. A
+ lot of work went into the driver to ensure that any kind of
+ conceivable API can be laid on top of the core driver. (Yes, the
+ driver internally leverages V4L to do its work but that really has
+ nothing to do with the API published by the driver to the outside
+ world.) The architecture allows for different APIs to
+ simultaneously access the driver. I have a strong sense of fairness
+ about APIs and also feel that it is a good design principle to keep
+ implementation and interface isolated from each other. Thus while
+ right now the V4L high level interface is the most complete, the
+ sysfs high level interface will work equally well for similar
+ functions, and there's no reason I see right now why it shouldn't be
+ possible to produce a DVB high level interface that can sit right
+ alongside V4L.
+
+ NOTE: Complete documentation on the pvrusb2 driver is contained in
+ the html files within the doc directory; these are exactly the same
+ as what is on the web site at the time. Browse those files
+ (especially the FAQ) before asking questions.
+
+
+Building
+
+ To build these modules essentially amounts to just running "Make",
+ but you need the kernel source tree nearby and you will likely also
+ want to set a few controlling environment variables first in order
+ to link things up with that source tree. Please see the Makefile
+ here for comments that explain how to do that.
+
+
+Source file list / functional overview:
+
+ (Note: The term "module" used below generally refers to loosely
+ defined functional units within the pvrusb2 driver and bears no
+ relation to the Linux kernel's concept of a loadable module.)
+
+ pvrusb2-audio.[ch] - This is glue logic that resides between this
+ driver and the msp3400.ko I2C client driver (which is found
+ elsewhere in V4L).
+
+ pvrusb2-context.[ch] - This module implements the context for an
+ instance of the driver. Everything else eventually ties back to
+ or is otherwise instanced within the data structures implemented
+ here. Hotplugging is ultimately coordinated here. All high level
+ interfaces tie into the driver through this module. This module
+ helps arbitrate each interface's access to the actual driver core,
+ and is designed to allow concurrent access through multiple
+ instances of multiple interfaces (thus you can for example change
+ the tuner's frequency through sysfs while simultaneously streaming
+ video through V4L out to an instance of mplayer).
+
+ pvrusb2-debug.h - This header defines a printk() wrapper and a mask
+ of debugging bit definitions for the various kinds of debug
+ messages that can be enabled within the driver.
+
+ pvrusb2-debugifc.[ch] - This module implements a crude command line
+ oriented debug interface into the driver. Aside from being part
+ of the process for implementing manual firmware extraction (see
+ the pvrusb2 web site mentioned earlier), probably I'm the only one
+ who has ever used this. It is mainly a debugging aid.
+
+ pvrusb2-eeprom.[ch] - This is glue logic that resides between this
+ driver the tveeprom.ko module, which is itself implemented
+ elsewhere in V4L.
+
+ pvrusb2-encoder.[ch] - This module implements all protocol needed to
+ interact with the Conexant mpeg2 encoder chip within the pvrusb2
+ device. It is a crude echo of corresponding logic in ivtv,
+ however the design goals (strict isolation) and physical layer
+ (proxy through USB instead of PCI) are enough different that this
+ implementation had to be completely different.
+
+ pvrusb2-hdw-internal.h - This header defines the core data structure
+ in the driver used to track ALL internal state related to control
+ of the hardware. Nobody outside of the core hardware-handling
+ modules should have any business using this header. All external
+ access to the driver should be through one of the high level
+ interfaces (e.g. V4L, sysfs, etc), and in fact even those high
+ level interfaces are restricted to the API defined in
+ pvrusb2-hdw.h and NOT this header.
+
+ pvrusb2-hdw.h - This header defines the full internal API for
+ controlling the hardware. High level interfaces (e.g. V4L, sysfs)
+ will work through here.
+
+ pvrusb2-hdw.c - This module implements all the various bits of logic
+ that handle overall control of a specific pvrusb2 device.
+ (Policy, instantiation, and arbitration of pvrusb2 devices fall
+ within the jurisdiction of pvrusb-context not here).
+
+ pvrusb2-i2c-chips-*.c - These modules implement the glue logic to
+ tie together and configure various I2C modules as they attach to
+ the I2C bus. There are two versions of this file. The "v4l2"
+ version is intended to be used in-tree alongside V4L, where we
+ implement just the logic that makes sense for a pure V4L
+ environment. The "all" version is intended for use outside of
+ V4L, where we might encounter other possibly "challenging" modules
+ from ivtv or older kernel snapshots (or even the support modules
+ in the standalone snapshot).
+
+ pvrusb2-i2c-cmd-v4l1.[ch] - This module implements generic V4L1
+ compatible commands to the I2C modules. It is here where state
+ changes inside the pvrusb2 driver are translated into V4L1
+ commands that are in turn send to the various I2C modules.
+
+ pvrusb2-i2c-cmd-v4l2.[ch] - This module implements generic V4L2
+ compatible commands to the I2C modules. It is here where state
+ changes inside the pvrusb2 driver are translated into V4L2
+ commands that are in turn send to the various I2C modules.
+
+ pvrusb2-i2c-core.[ch] - This module provides an implementation of a
+ kernel-friendly I2C adaptor driver, through which other external
+ I2C client drivers (e.g. msp3400, tuner, lirc) may connect and
+ operate corresponding chips within the the pvrusb2 device. It is
+ through here that other V4L modules can reach into this driver to
+ operate specific pieces (and those modules are in turn driven by
+ glue logic which is coordinated by pvrusb2-hdw, doled out by
+ pvrusb2-context, and then ultimately made available to users
+ through one of the high level interfaces).
+
+ pvrusb2-io.[ch] - This module implements a very low level ring of
+ transfer buffers, required in order to stream data from the
+ device. This module is *very* low level. It only operates the
+ buffers and makes no attempt to define any policy or mechanism for
+ how such buffers might be used.
+
+ pvrusb2-ioread.[ch] - This module layers on top of pvrusb2-io.[ch]
+ to provide a streaming API usable by a read() system call style of
+ I/O. Right now this is the only layer on top of pvrusb2-io.[ch],
+ however the underlying architecture here was intended to allow for
+ other styles of I/O to be implemented with additonal modules, like
+ mmap()'ed buffers or something even more exotic.
+
+ pvrusb2-main.c - This is the top level of the driver. Module level
+ and USB core entry points are here. This is our "main".
+
+ pvrusb2-sysfs.[ch] - This is the high level interface which ties the
+ pvrusb2 driver into sysfs. Through this interface you can do
+ everything with the driver except actually stream data.
+
+ pvrusb2-tuner.[ch] - This is glue logic that resides between this
+ driver and the tuner.ko I2C client driver (which is found
+ elsewhere in V4L).
+
+ pvrusb2-util.h - This header defines some common macros used
+ throughout the driver. These macros are not really specific to
+ the driver, but they had to go somewhere.
+
+ pvrusb2-v4l2.[ch] - This is the high level interface which ties the
+ pvrusb2 driver into video4linux. It is through here that V4L
+ applications can open and operate the driver in the usual V4L
+ ways. Note that **ALL** V4L functionality is published only
+ through here and nowhere else.
+
+ pvrusb2-video-*.[ch] - This is glue logic that resides between this
+ driver and the saa711x.ko I2C client driver (which is found
+ elsewhere in V4L). Note that saa711x.ko used to be known as
+ saa7115.ko in ivtv. There are two versions of this; one is
+ selected depending on the particular saa711[5x].ko that is found.
+
+ pvrusb2.h - This header contains compile time tunable parameters
+ (and at the moment the driver has very little that needs to be
+ tuned).

+ This single function is key to pretty much everything. The pvrusb2
+ device can logically be viewed as a series of subsystems which can be
+ stopped / started or unconfigured / configured. To get things streaming,
+ one must configure everything and start everything, but there may be
+ various reasons over time to deconfigure something or stop something.
+ This function handles all of this activity. Everything EVERYWHERE that
+ must affect a subsystem eventually comes here to do the work.
+
+ The current state of all subsystems is represented by a single bit mask,
+ known as subsys_enabled_mask. The bit positions are defined by the
+ PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
+ time the set of configured or active subsystems can be queried just by
+ looking at that mask. To change bits in that mask, this function here
+ must be called. The "msk" argument indicates which bit positions to
+ change, and the "val" argument defines the new values for the positions
+ defined by "msk".
+
+ There is a priority ordering of starting / stopping things, and for
+ multiple requested changes, this function implements that ordering.
+ (Thus we will act on a request to load encoder firmware before we
+ configure the encoder.) In addition to priority ordering, there is a
+ recovery strategy implemented here. If a particular step fails and we
+ detect that failure, this function will clear the affected subsystem bits
+ and restart. Thus we have a means for recovering from a dead encoder:
+ Clear all bits that correspond to subsystems that we need to restart /
+ reconfigure and start over.

+ This next batch of horrible preprocessor hackery is needed because the
+ kernel's class_device_attribute mechanism fails to pass the actual
+ attribute through to the show / store functions, which means we have no
+ way to package up any attribute-specific parameters, like for example the
+ control id. So we work around this brain-damage by encoding the control
+ id into the show / store functions themselves and pick the function based
+ on the control id we're setting up. These macros try to ease the pain.

+ the array, and (b) cover the entire registration process later
+ on with this same mutex. Thus if we get inside the mutex here,
+ then we can be assured that the registration process actually
