-
-This set of notes is intended mainly for kernel developers, occasional
-or full-time, but sysadmins and power users may find parts of it useful
-as well.  It assumes at least a basic familiarity with CVS, both at a
-user level (use on the cmd line) and at a higher level (client-server model).
-Due to the author's background, an operation may be described in terms
-of CVS, or in terms of how that operation differs from CVS.
-
-This is -not- intended to be BitKeeper documentation.  Always run
-"bk help <command>" or in X "bk helptool <command>" for reference
-documentation.
-

-BitKeeper Concepts
-------------------
-
-In the true nature of the Internet itself, BitKeeper is a distributed
-system.  When applied to revision control, this means doing away with
-client-server, and changing to a parent-child model... essentially
-peer-to-peer.  On the developer's end, this also represents a
-fundamental disruption in the standard workflow of changes, commits,
-and merges.  You will need to take a few minutes to think about
-how to best work under BitKeeper, and re-optimize things a bit.
-In some sense it is a bit radical, because it might described as
-tossing changes out into a maelstrom and having them magically
-land at the right destination... but I'm getting ahead of myself.
-
-Let's start with this progression:
-Each BitKeeper source tree on disk is a repository unto itself.
-Each repository has a parent (except the root/original, of course).
-Each repository contains a set of a changesets ("csets").
-Each cset is one or more changed files, bundled together.
-
-Each tree is a repository, so all changes are checked into the local
-tree.  When a change is checked in, all modified files are grouped
-into a logical unit, the changeset.  Internally, BK links these
-changesets in a tree, representing various converging and diverging
-lines of development.  These changesets are the bread and butter of
-the BK system.
-
-After the concept of changesets, the next thing you need to get used
-to is having multiple copies of source trees lying around.  This -really-
-takes some getting used to, for some people.  Separate source trees
-are the means in BitKeeper by which you delineate parallel lines
-of development, both minor and major.  What would be branches in
-CVS become separate source trees, or "clones" in BitKeeper [heh,
-or Star Wars] terminology.
-
-Clones and changesets are the tools from which most of the power of
-BitKeeper is derived.  As mentioned earlier, each clone has a parent,
-the tree used as the source when the new clone was created.  In a
-CVS-like setup, the parent would be a remote server on the Internet,
-and the child is your local clone of that tree.
-
-Once you have established a common baseline between two source trees --
-a common parent -- then you can merge changesets between those two
-trees with ease.  Merging changes into a tree is called a "pull", and
-is analagous to 'cvs update'.  A pull downloads all the changesets in
-the remote tree you do not have, and merges them.  Sending changes in
-one tree to another tree is called a "push".  Push sends all changes
-in the local tree the remote does not yet have, and merges them.
-
-From these concepts come some initial command examples:
-
-1) bk clone -q http://linux.bkbits.net/linux-2.5 linus-2.5
-Download a 2.5 stock kernel tree, naming it "linus-2.5" in the local dir.
-The "-q" disables listing every single file as it is downloaded.
-
-2) bk clone -ql linus-2.5 alpha-2.5
-Create a separate source tree for the Alpha AXP architecture.
-The "-l" uses hard links instead of copying data, since both trees are
-on the local disk.  You can also replace the above with "bk lclone -q ..."
-
-You only clone a tree -once-.  After cloning the tree lives a long time
-on disk, being updating by pushes and pulls.
-
-3) cd alpha-2.5 ; bk pull http://gkernel.bkbits.net/alpha-2.5
-Download changes in "alpha-2.5" repository which are not present
-in the local repository, and merge them into the source tree.
-
-4) bk -r co -q
-Because every tree is a repository, files must be checked out before
-they will be in their standard places in the source tree.
-
-5)	bk vi fs/inode.c				# example change...
-	bk citool					# checkin, using X tool
-	bk push bk://gkernel@bkbits.net/alpha-2.5	# upload change
-Typical example of a BK sequence that would replace the analagous CVS
-situation,
-	vi fs/inode.c
-	cvs commit
-
-As this is just supposed to be a quick BK intro, for more in-depth
-tutorials, live working demos, and docs, see http://www.bitkeeper.com/

-
-BK and Kernel Development Workflow
-----------------------------------
-Currently the latest 2.5 tree is available via "bk clone $URL"
-and "bk pull $URL" at http://linux.bkbits.net/linux-2.5
-This should change in a few weeks to a kernel.org URL.
-
-
-A big part of using BitKeeper is organizing the various trees you have
-on your local disk, and organizing the flow of changes among those
-trees, and remote trees.  If one were to graph the relationships between
-a desired BK setup, you are likely to see a few-many-few graph, like
-this:
-
-		    linux-2.5
-		        |
-	       merge-to-linus-2.5
-		 /    |      |
-	        /     |      |
-	vm-hacks  bugfixes  filesys   personal-hacks
-	      \	      |	     |		/
-	       \      |      |         /
-		\     |      |        /
-	         testing-and-validation
-
-Since a "bk push" sends all changes not in the target tree, and
-since a "bk pull" receives all changes not in the source tree, you want
-to make sure you are only pushing specific changes to the desired tree,
-not all changes from "peer parent" trees.  For example, pushing a change
-from the testing-and-validation tree would probably be a bad idea,
-because it will push all changes from vm-hacks, bugfixes, filesys, and
-personal-hacks trees into the target tree.
-
-One would typically work on only one "theme" at a time, either
-vm-hacks or bugfixes or filesys, keeping those changes isolated in
-their own tree during development, and only merge the isolated with
-other changes when going upstream (to Linus or other maintainers) or
-downstream (to your "union" trees, like testing-and-validation above).
-
-It should be noted that some of this separation is not just recommended
-practice, it's actually [for now] -enforced- by BitKeeper.  BitKeeper
-requires that changesets maintain a certain order, which is the reason
-that "bk push" sends all local changesets the remote doesn't have.  This
-separation may look like a lot of wasted disk space at first, but it
-helps when two unrelated changes may "pollute" the same area of code, or
-don't follow the same pace of development, or any other of the standard
-reasons why one creates a development branch.
-
-Small development branches (clones) will appear and disappear:
-
-	-------- A --------- B --------- C --------- D -------
-	          \                                 /
-		   -----short-term devel branch-----
-
-While long-term branches will parallel a tree (or trees), with period
-merge points.  In this first example, we pull from a tree (pulls,
-"\") periodically, such as what occurs when tracking changes in a
-vendor tree, never pushing changes back up the line:
-
-	-------- A --------- B --------- C --------- D -------
-	          \                       \           \
-	           ----long-term devel branch-----------------
-
-And then a more common case in Linux kernel development, a long term
-branch with periodic merges back into the tree (pushes, "/"):
-
-	-------- A --------- B --------- C --------- D -------
-	          \                       \         / \
-	           ----long-term devel branch-----------------
-

-Submitting Changes to Linus
----------------------------
-There's a bit of an art, or style, of submitting changes to Linus.
-Since Linus's tree is now (you might say) fully integrated into the
-distributed BitKeeper system, there are several prerequisites to
-properly submitting a BitKeeper change.  All these prereq's are just
-general cleanliness of BK usage, so as people become experts at BK, feel
-free to optimize this process further (assuming Linus agrees, of
-course).
-
-
-
-0) Make sure your tree was originally cloned from the linux-2.5 tree
-created by Linus.  If your tree does not have this as its ancestor, it
-is impossible to reliably exchange changesets.
-
-
-
-1) Pay attention to your commit text.  The commit message that
-accompanies each changeset you submit will live on forever in history,
-and is used by Linus to accurately summarize the changes in each
-pre-patch.  Remember that there is no context, so
-	"fix for new scheduler changes"
-would be too vague, but
-	"fix mips64 arch for new scheduler switch_to(), TIF_xxx semantics"
-would be much better.
-
-You can and should use the command "bk comment -C<rev>" to update the
-commit text, and improve it after the fact.  This is very useful for
-development: poor, quick descriptions during development, which get
-cleaned up using "bk comment" before issuing the "bk push" to submit the
-changes.
-
-
-
-2) Include an Internet-available URL for Linus to pull from, such as
-
-	Pull from:  http://gkernel.bkbits.net/net-drivers-2.5
-
-
-
-3) Include a summary and "diffstat -p1" of each changeset that will be
-downloaded, when Linus issues a "bk pull".  The author auto-generates
-these summaries using "bk changes -L <parent>", to obtain a listing
-of all the pending-to-send changesets, and their commit messages.
-
-It is important to show Linus what he will be downloading when he issues
-a "bk pull", to reduce the time required to sift the changes once they
-are downloaded to Linus's local machine.
-
-IMPORTANT NOTE:  One of the features of BK is that your repository does
-not have to be up to date, in order for Linus to receive your changes.
-It is considered a courtesy to keep your repository fairly recent, to
-lessen any potential merge work Linus may need to do.
-
-
-4) Split up your changes.  Each maintainer<->Linus situation is likely
-to be slightly different here, so take this just as general advice.  The
-author splits up changes according to "themes" when merging with Linus.
-Simultaneous pushes from local development go to special trees which
-exist solely to house changes "queued" for Linus.  Example of the trees:
-
-	net-drivers-2.5 -- on-going net driver maintenance
-	vm-2.5 -- VM-related changes
-	fs-2.5 -- filesystem-related changes
-
-Linus then has much more freedom for pulling changes.  He could (for
-example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their
-changes, but hold off net-drivers-2.5 because of a change that needs
-more discussion.
-
-Other maintainers may find that a single linus-pull-from tree is
-adequate for passing BK changesets to him.
-
-
-
-Frequently Answered Questions
------------------------------
-1) How do I change the e-mail address shown in the changelog?
-A. When you run "bk citool" or "bk commit", set environment
-   variables BK_USER and BK_HOST to the desired username
-   and host/domain name.
-
-
-2) How do I use tags / get a diff between two kernel versions?
-A. Pass the tags Linus uses to 'bk export'.
-
-ChangeSets are in a forward-progressing order, so it's pretty easy
-to get a snapshot starting and ending at any two points in time.
-Linus puts tags on each release and pre-release, so you could use
-these two examples:
-
-    bk export -tpatch -hdu -rv2.5.4,v2.5.5 | less
-        # creates patch-2.5.5 essentially
-    bk export -tpatch -du -rv2.5.5-pre1,v2.5.5 | less
-        # changes from pre1 to final
-
-A tag is just an alias for a specific changeset... and since changesets
-are ordered, a tag is thus a marker for a specific point in time (or
-specific state of the tree).
-
-
-3) Is there an easy way to generate One Big Patch versus mainline,
-   for my long-lived kernel branch?
-A. Yes.  This requires BK 3.x, though.

+
+
+1. Introduction
+
+cpufreq-stats is a driver that provices CPU frequency statistics for each CPU.
+This statistics is provided in /sysfs as a bunch of read_only interfaces. This
+interface (when configured) will appear in a seperate directory under cpufreq
+in /sysfs (<sysfs root>/devices/system/cpu/cpuX/cpufreq/stats/) for each CPU.
+Various statistics will form read_only files under this directory.
+
+This driver is designed to be independent of any particular cpufreq_driver
+that may be running on your CPU. So, it will work with any cpufreq_driver.
+
+
+2. Statistics Provided (with example)
+
+cpufreq stats provides following statistics (explained in detail below).
+-  time_in_state
+-  total_trans
+-  trans_table
+
+All the statistics will be from the time the stats driver has been inserted 
+to the time when a read of a particular statistic is done. Obviously, stats 
+driver will not have any information about the the frequcny transitions before
+the stats driver insertion.

+--------------------------------------------------------------------------------
+
+-  time_in_state
+This gives the amount of time spent in each of the frequencies supported by
+this CPU. The cat output will have "<frequency> <time>" pair in each line, which
+will mean this CPU spent <time> usertime units of time at <frequency>. Output
+will have one line for each of the supported freuencies. usertime units here 
+is 10mS (similar to other time exported in /proc).

+--------------------------------------------------------------------------------
+
+
+-  total_trans
+This gives the total number of frequency transitions on this CPU. The cat 
+output will have a single count which is the total number of frequency
+transitions.

+--------------------------------------------------------------------------------
+<mysystem>:/sys/devices/system/cpu/cpu0/cpufreq/stats # cat total_trans

+--------------------------------------------------------------------------------
+
+-  trans_table
+This will give a fine grained information about all the CPU frequency
+transitions. The cat output here is a two dimensional matrix, where an entry
+<i,j> (row i, column j) represents the count of number of transitions from 
+Freq_i to Freq_j. Freq_i is in descending order with increasing rows and 
+Freq_j is in descending order with increasing columns. The output here also 
+contains the actual freq values for each row and column for better readability.

+Config Main Menu
+	Power management options (ACPI, APM)  --->
+		CPU Frequency scaling  --->
+			[*] CPU Frequency scaling
+			<*>   CPU frequency translation statistics 
+			[*]     CPU frequency translation statistics details
+
+
+"CPU Frequency scaling" (CONFIG_CPU_FREQ) should be enabled to configure
+cpufreq-stats.
+
+"CPU frequency translation statistics" (CONFIG_CPU_FREQ_STAT) provides the
+basic statistics which includes time_in_state and total_trans.
+
+"CPU frequency translation statistics details" (CONFIG_CPU_FREQ_STAT_DETAILS)
+provides fine grained cpufreq stats by trans_table. The reason for having a
+seperate config option for trans_table is:
+- trans_table goes against the traditional /sysfs rule of one value per
+  interface. It provides a whole bunch of value in a 2 dimensional matrix
+  form.
+
+Once these two options are enabled and your CPU supports cpufrequency, you
+will be able to see the CPU frequency statistics in /sysfs.

Documentation/dvb/README.flexcop

@@ -0,0 +1,205 @@
+This README escorted the skystar2-driver rewriting procedure. It describes the
+state of the new flexcop-driver set and some internals are written down here
+too.
+
+This document hopefully describes things about the flexcop and its
+device-offsprings. Goal was to write an easy-to-write and easy-to-read set of
+drivers based on the skystar2.c and other information.
+
+Remark: flexcop-pci.c was a copy of skystar2.c, but every line has been
+touched and rewritten.
+
+History & News
+==============
+  2005-04-01 - correct USB ISOC transfers (thanks to Vadim Catana)
+
+
+
+
+General coding processing
+=========================
+
+We should proceed as follows (as long as no one complains):
+
+0) Think before start writing code!
+
+1) rewriting the skystar2.c with the help of the flexcop register descriptions
+and splitting up the files to a pci-bus-part and a flexcop-part.
+The new driver will be called b2c2-flexcop-pci.ko/b2c2-flexcop-usb.ko for the
+device-specific part and b2c2-flexcop.ko for the common flexcop-functions.
+
+2) Search for errors in the leftover of flexcop-pci.c (compare with pluto2.c
+and other pci drivers)
+
+3) make some beautification (see 'Improvements when rewriting (refactoring) is
+done')
+
+4) Testing the new driver and maybe substitute the skystar2.c with it, to reach
+a wider tester audience.
+
+5) creating an usb-bus-part using the already written flexcop code for the pci
+card.
+
+Idea: create a kernel-object for the flexcop and export all important
+functions. This option saves kernel-memory, but maybe a lot of functions have
+to be exported to kernel namespace.
+
+
+Current situation
+=================
+
+0) Done :)
+1) Done (some minor issues left)
+2) Done
+3) Not ready yet, more information is necessary
+4) next to be done (see the table below)
+5) USB driver is working (yes, there are some minor issues)
+
+What seems to be ready?
+-----------------------
+
+1) Rewriting
+1a) i2c is cut off from the flexcop-pci.c and seems to work
+1b) moved tuner and demod stuff from flexcop-pci.c to flexcop-tuner-fe.c
+1c) moved lnb and diseqc stuff from flexcop-pci.c to flexcop-tuner-fe.c
+1e) eeprom (reading MAC address)
+1d) sram (no dynamic sll size detection (commented out) (using default as JJ told me))
+1f) misc. register accesses for reading parameters (e.g. resetting, revision)
+1g) pid/mac filter (flexcop-hw-filter.c)
+1i) dvb-stuff initialization in flexcop.c (done)
+1h) dma stuff (now just using the size-irq, instead of all-together, to be done)
+1j) remove flexcop initialization from flexcop-pci.c completely (done)
+1l) use a well working dma IRQ method (done, see 'Known bugs and problems and TODO')
+1k) cleanup flexcop-files (remove unused EXPORT_SYMBOLs, make static from
+non-static where possible, moved code to proper places)
+
+2) Search for errors in the leftover of flexcop-pci.c (partially done)
+5a) add MAC address reading
+5c) feeding of ISOC data to the software demux (format of the isochronous data
+and speed optimization, no real error) (thanks to Vadim Catana)
+
+What to do in the near future?
+--------------------------------------
+(no special order here)
+
+5) USB driver
+5b) optimize isoc-transfer (submitting/killing isoc URBs when transfer is starting)
+
+Testing changes

+Known bugs and problems and TODO
+--------------------------------
+
+1g/h/l) when pid filtering is enabled on the pci card
+
+DMA usage currently:
+  The DMA is splitted in 2 equal-sized subbuffers. The Flexcop writes to first
+  address and triggers an IRQ when it's full and starts writing to the second
+  address. When the second address is full, the IRQ is triggered again, and
+  the flexcop writes to first address again, and so on.
+  The buffersize of each address is currently 640*188 bytes.
+
+  Problem is, when using hw-pid-filtering and doing some low-bandwidth
+  operation (like scanning) the buffers won't be filled enough to trigger
+  the IRQ. That's why:
+
+  When PID filtering is activated, the timer IRQ is used. Every 1.97 ms the IRQ
+  is triggered.  Is the current write address of DMA1 different to the one
+  during the last IRQ, then the data is passed to the demuxer.
+
+  There is an additional DMA-IRQ-method: packet count IRQ. This isn't
+  implemented correctly yet.
+
+  The solution is to disable HW PID filtering, but I don't know how the DVB
+  API software demux behaves on slow systems with 45MBit/s TS.
+
+Solved bugs :)
+--------------
+1g) pid-filtering (somehow pid index 4 and 5 (EMM_PID and ECM_PID) aren't
+working)
+SOLUTION: also index 0 was affected, because net_translation is done for
+these indexes by default
+
+5b) isochronous transfer does only work in the first attempt (for the Sky2PC
+USB, Air2PC is working) SOLUTION: the flexcop was going asleep and never really
+woke up again (don't know if this need fixes, see
+flexcop-fe-tuner.c:flexcop_sleep)
+
+NEWS: when the driver is loaded and unloaded and loaded again (w/o doing
+anything in the while the driver is loaded the first time), no transfers take
+place anymore.
+
+Improvements when rewriting (refactoring) is done
+=================================================
+
+- split sleeping of the flexcop (misc_204.ACPI3_sig = 1;) from lnb_control
+  (enable sleeping for other demods than dvb-s)
+- add support for CableStar (stv0297 Microtune 203x/ALPS) (almost done, incompatibilities with the Nexus-CA)
+
+Debugging
+---------
+- add verbose debugging to skystar2.c (dump the reg_dw_data) and compare it
+  with this flexcop, this is important, because i2c is now using the
+  flexcop_ibi_value union from flexcop-reg.h (do you have a better idea for
+  that, please tell us so).
+
+Everything which is identical in the following table, can be put into a common
+flexcop-module.
+
+                  PCI                  USB
+-------------------------------------------------------------------------------
+Different:
+Register access:  accessing IO memory  USB control message
+I2C bus:          I2C bus of the FC    USB control message
+Data transfer:    DMA                  isochronous transfer
+EEPROM transfer:  through i2c bus      not clear yet
+
+Identical:
+Streaming:                 accessing registers
+PID Filtering:             accessing registers
+Sram destinations:         accessing registers
+Tuner/Demod:                     I2C bus
+DVB-stuff:            can be written for common use

+* For the user
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+NOTE: This document describes the usage of the high level CI API as
+in accordance to the Linux DVB API. This is a not a documentation for the,
+existing low level CI API.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To utilize the High Level CI capabilities,
+
+(1*) This point is valid only for the Twinhan/clones
+  For the Twinhan/Twinhan clones, the dst_ca module handles the CI
+  hardware handling.This module is loaded automatically if a CI
+  (Common Interface, that holds the CAM (Conditional Access Module)
+  is detected.
+
+(2) one requires a userspace application, ca_zap. This small userland
+  application is in charge of sending the descrambling related information
+  to the CAM.
+
+This application requires the following to function properly as of now.
+
+	(a) Tune to a valid channel, with szap.
+	  eg: $ szap -c channels.conf -r "TMC" -x
+
+	(b) a channels.conf containing a valid PMT PID
+
+	  eg: TMC:11996:h:0:27500:278:512:650:321
+
+	  here 278 is a valid PMT PID. the rest of the values are the
+	  same ones that szap uses.
+
+	(c) after running a szap, you have to run ca_zap, for the
+	  descrambler to function,
+
+	  eg: $ ca_zap patched_channels.conf "TMC"
+
+	  The patched means a patch to apply to scan, such that scan can
+	  generate a channels.conf_with pmt, which has this PMT PID info
+	  (NOTE: szap cannot use this channels.conf with the PMT_PID)
+
+
+	(d) Hopeflly Enjoy your favourite subscribed channel as you do with
+	  a FTA card.
+
+(3) Currently ca_zap, and dst_test, both are meant for demonstration
+  purposes only, they can become full fledged applications if necessary.
+
+
+* Cards that fall in this category
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+At present the cards that fall in this category are the Twinhan and it's
+clones, these cards are available as VVMER, Tomato, Hercules, Orange and
+so on.
+
+* CI modules that are supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The CI module support is largely dependant upon the firmware on the cards
+Some cards do support almost all of the available CI modules. There is
+nothing much that can be done in order to make additional CI modules
+working with these cards.
+
+Modules that have been tested by this driver at present are
+
+(1) Irdeto 1 and 2 from SCM
+(2) Viaccess from SCM
+(3) Dragoncam
+
+* The High level CI API
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* For the programmer
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+With the High Level CI approach any new card with almost any random
+architecture can be implemented with this style, the definitions
+insidethe switch statement can be easily adapted for any card, thereby
+eliminating the need for any additional ioctls.
+
+The disadvantage is that the driver/hardware has to manage the rest. For
+the application programmer it would be as simple as sending/receiving an
+array to/from the CI ioctls as defined in the Linux DVB API. No changes
+have been made in the API to accomodate this feature.
+
+
+* Why the need for another CI interface ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This is one of the most commonly asked question. Well a nice question.
+Strictly speaking this is not a new interface.
+
+The CI interface is defined in the DVB API in ca.h as
+
+typedef struct ca_slot_info {
+	int num;               /* slot number */
+
+	int type;              /* CA interface this slot supports */
+#define CA_CI            1     /* CI high level interface */

+
+This CI interface follows the CI high level interface, which is not
+implemented by most applications. Hence this area is revisited.
+
+This CI interface is quite different in the case that it tries to
+accomodate all other CI based devices, that fall into the other categories
+
+This means that this CI interface handles the EN50221 style tags in the
+Application layer only and no session management is taken care of by the
+application. The driver/hardware will take care of all that.
+
+This interface is purely an EN50221 interface exchanging APDU's. This
+means that no session management, link layer or a transport layer do
+exist in this case in the application to driver communication. It is
+as simple as that. The driver/hardware has to take care of that.
+
+
+With this High Level CI interface, the interface can be defined with the
+regular ioctls.
+
+All these ioctls are also valid for the High level CI interface
+
+#define CA_RESET          _IO('o', 128)
+#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
+#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)

+#define CA_SET_PID        _IOW('o', 135, ca_pid_t)
+
+
+On querying the device, the device yields information thus

+
+
+Not all ioctl's are implemented in the driver from the API, the other
+features of the hardware that cannot be implemented by the API are achieved
+using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
+used to exchange the data to maintain compatibility with other hardware.

+typedef struct ca_msg {
+	unsigned int index;

+	unsigned int length;

-The kernel now supports the ability to place a device in a low-power

-module is removed. 
-
-Each device contains a 'detach_state' file in its sysfs directory
-which can be used to control this state. Reading from this file
-displays what the current detach state is set to. This is 0 (On) by
-default. A user may write a positive integer value to this file in the
-range of 1-4 inclusive. 
-
-A value of 1-3 will indicate the device should be placed in that
-low-power state, which will cause ->suspend() to be called for that
-device. A value of 4 indicates that the device should be shutdown, so
-->shutdown() will be called for that device. 
-
-The driver is responsible for reinitializing the device when the
-module is re-inserted during it's ->probe() (or equivalent) method. 
-The driver core will not call any extra functions when binding the
-device to the driver.
