+Description:
+		Writing a device ID to this file will attempt to
+		dynamically add a new device ID to a PCI device driver.
+		This may allow the driver to support more hardware than
+		was included in the driver's static device ID support
+		table at compile time.  The format for the device ID is:
+		VVVV DDDD SVVV SDDD CCCC MMMM PPPP.  That is Vendor ID,
+		Device ID, Subsystem Vendor ID, Subsystem Device ID,
+		Class, Class Mask, and Private Driver Data.  The Vendor ID
+		and Device ID fields are required, the rest are optional.
+		Upon successfully adding an ID, the driver will probe
+		for the device and attempt to bind to it.  For example:
+		# echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id

+     <title>Frame Buffer Library</title>
+
+     <para>
+       The frame buffer drivers depend heavily on four data structures.
+       These structures are declared in include/linux/fb.h.  They are
+       fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
+       The last three can be made available to and from userland.
+     </para>
+
+     <para>
+       fb_info defines the current state of a particular video card.
+       Inside fb_info, there exists a fb_ops structure which is a
+       collection of needed functions to make fbdev and fbcon work.
+       fb_info is only visible to the kernel.
+     </para>
+
+     <para>
+       fb_var_screeninfo is used to describe the features of a video card
+       that are user defined.  With fb_var_screeninfo, things such as
+       depth and the resolution may be defined.
+     </para>
+
+     <para>
+       The next structure is fb_fix_screeninfo. This defines the
+       properties of a card that are created when a mode is set and can't
+       be changed otherwise.  A good example of this is the start of the
+       frame buffer memory.  This "locks" the address of the frame buffer
+       memory, so that it cannot be changed or moved.
+     </para>
+
+     <para>
+       The last structure is fb_monospecs. In the old API, there was
+       little importance for fb_monospecs. This allowed for forbidden things
+       such as setting a mode of 800x600 on a fix frequency monitor. With
+       the new API, fb_monospecs prevents such things, and if used
+       correctly, can prevent a monitor from being cooked.  fb_monospecs
+       will not be useful until kernels 2.5.x.

+      <title>Serial Peripheral Interface (SPI)</title>
+  <para>
+	SPI is the "Serial Peripheral Interface", widely used with
+	embedded systems because it is a simple and efficient
+	interface:  basically a multiplexed shift register.
+	Its three signal wires hold a clock (SCK, often in the range
+	of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
+	a "Master In, Slave Out" (MISO) data line.
+	SPI is a full duplex protocol; for each bit shifted out the
+	MOSI line (one per clock) another is shifted in on the MISO line.
+	Those bits are assembled into words of various sizes on the
+	way to and from system memory.
+	An additional chipselect line is usually active-low (nCS);
+	four signals are normally used for each peripheral, plus
+	sometimes an interrupt.
+  </para>
+  <para>
+	The SPI bus facilities listed here provide a generalized
+	interface to declare SPI busses and devices, manage them
+	according to the standard Linux driver model, and perform
+	input/output operations.
+	At this time, only "master" side interfaces are supported,
+	where Linux talks to SPI peripherals and does not implement
+	such a peripheral itself.
+	(Interfaces to support implementing SPI slaves would
+	necessarily look different.)
+  </para>
+  <para>
+	The programming interface is structured around two kinds of driver,
+	and two kinds of device.
+	A "Controller Driver" abstracts the controller hardware, which may
+	be as simple as a set of GPIO pins or as complex as a pair of FIFOs
+	connected to dual DMA engines on the other side of the SPI shift
+	register (maximizing throughput).  Such drivers bridge between
+	whatever bus they sit on (often the platform bus) and SPI, and
+	expose the SPI side of their device as a
+	<structname>struct spi_master</structname>.
+	SPI devices are children of that master, represented as a
+	<structname>struct spi_device</structname> and manufactured from
+	<structname>struct spi_board_info</structname> descriptors which
+	are usually provided by board-specific initialization code.
+	A <structname>struct spi_driver</structname> is called a
+	"Protocol Driver", and is bound to a spi_device using normal
+	driver model calls.
+  </para>
+  <para>
+	The I/O model is a set of queued messages.  Protocol drivers
+	submit one or more <structname>struct spi_message</structname>
+	objects, which are processed and completed asynchronously.
+	(There are synchronous wrappers, however.)  Messages are
+	built from one or more <structname>struct spi_transfer</structname>
+	objects, each of which wraps a full duplex SPI transfer.
+	A variety of protocol tweaking options are needed, because
+	different chips adopt very different policies for how they
+	use the bits transferred with SPI.

+     <title>I<superscript>2</superscript>C and SMBus Subsystem</title>
+
+     <para>
+	I<superscript>2</superscript>C (or without fancy typography, "I2C")
+	is an acronym for the "Inter-IC" bus, a simple bus protocol which is
+	widely used where low data rate communications suffice.
+	Since it's also a licensed trademark, some vendors use another
+	name (such as "Two-Wire Interface", TWI) for the same bus.
+	I2C only needs two signals (SCL for clock, SDA for data), conserving
+	board real estate and minimizing signal quality issues.
+	Most I2C devices use seven bit addresses, and bus speeds of up
+	to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
+	found wide use.
+	I2C is a multi-master bus; open drain signaling is used to
+	arbitrate between masters, as well as to handshake and to
+	synchronize clocks from slower clients.
+     </para>
+
+     <para>
+	The Linux I2C programming interfaces support only the master
+	side of bus interactions, not the slave side.
+	The programming interface is structured around two kinds of driver,
+	and two kinds of device.
+	An I2C "Adapter Driver" abstracts the controller hardware; it binds
+	to a physical device (perhaps a PCI device or platform_device) and
+	exposes a <structname>struct i2c_adapter</structname> representing
+	each I2C bus segment it manages.
+	On each I2C bus segment will be I2C devices represented by a
+	<structname>struct i2c_client</structname>.  Those devices will
+	be bound to a <structname>struct i2c_driver</structname>,
+	which should follow the standard Linux driver model.
+	(At this writing, a legacy model is more widely used.)
+	There are functions to perform various I2C protocol operations; at
+	this writing all such functions are usable only from task context.
+     </para>
+
+     <para>
+	The System Management Bus (SMBus) is a sibling protocol.  Most SMBus
+	systems are also I2C conformant.  The electrical constraints are
+	tighter for SMBus, and it standardizes particular protocol messages
+	and idioms.  Controllers that support I2C can also support most
+	SMBus operations, but SMBus controllers don't support all the protocol
+	options that an I2C controller will.
+	There are functions to perform various SMBus protocol operations,
+	either using I2C primitives or by issuing SMBus commands to
+	i2c_adapter devices which don't support those I2C operations.

-       The frame buffer drivers depend heavily on four data structures.  
-       These structures are declared in include/linux/fb.h.  They are 
-       fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs. 
-       The last three can be made available to and from userland. 
-     </para>
-
-     <para>
-       fb_info defines the current state of a particular video card. 
-       Inside fb_info, there exists a fb_ops structure which is a 
-       collection of needed functions to make fbdev and fbcon work.
-       fb_info is only visible to the kernel.
-     </para>
-
-     <para>
-       fb_var_screeninfo is used to describe the features of a video card 
-       that are user defined.  With fb_var_screeninfo, things such as
-       depth and the resolution may be defined.
-     </para>
-
-     <para>
-       The next structure is fb_fix_screeninfo. This defines the 
-       properties of a card that are created when a mode is set and can't 
-       be changed otherwise.  A good example of this is the start of the 
-       frame buffer memory.  This "locks" the address of the frame buffer
-       memory, so that it cannot be changed or moved.
-     </para>
-
-     <para>
-       The last structure is fb_monospecs. In the old API, there was 
-       little importance for fb_monospecs. This allowed for forbidden things 
-       such as setting a mode of 800x600 on a fix frequency monitor. With 
-       the new API, fb_monospecs prevents such things, and if used 
-       correctly, can prevent a monitor from being cooked.  fb_monospecs
-       will not be useful until kernels 2.5.x.

-      <title>Serial Peripheral Interface (SPI)</title>
-  <para>
-	SPI is the "Serial Peripheral Interface", widely used with
-	embedded systems because it is a simple and efficient
-	interface:  basically a multiplexed shift register.
-	Its three signal wires hold a clock (SCK, often in the range
-	of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
-	a "Master In, Slave Out" (MISO) data line.
-	SPI is a full duplex protocol; for each bit shifted out the
-	MOSI line (one per clock) another is shifted in on the MISO line.
-	Those bits are assembled into words of various sizes on the
-	way to and from system memory.
-	An additional chipselect line is usually active-low (nCS);
-	four signals are normally used for each peripheral, plus
-	sometimes an interrupt.
-  </para>
-  <para>
-	The SPI bus facilities listed here provide a generalized
-	interface to declare SPI busses and devices, manage them
-	according to the standard Linux driver model, and perform
-	input/output operations.
-	At this time, only "master" side interfaces are supported,
-	where Linux talks to SPI peripherals and does not implement
-	such a peripheral itself.
-	(Interfaces to support implementing SPI slaves would
-	necessarily look different.)
-  </para>
-  <para>
-	The programming interface is structured around two kinds of driver,
-	and two kinds of device.
-	A "Controller Driver" abstracts the controller hardware, which may
-	be as simple as a set of GPIO pins or as complex as a pair of FIFOs
-	connected to dual DMA engines on the other side of the SPI shift
-	register (maximizing throughput).  Such drivers bridge between
-	whatever bus they sit on (often the platform bus) and SPI, and
-	expose the SPI side of their device as a
-	<structname>struct spi_master</structname>.
-	SPI devices are children of that master, represented as a
-	<structname>struct spi_device</structname> and manufactured from
-	<structname>struct spi_board_info</structname> descriptors which
-	are usually provided by board-specific initialization code.
-	A <structname>struct spi_driver</structname> is called a
-	"Protocol Driver", and is bound to a spi_device using normal
-	driver model calls.
-  </para>
-  <para>
-	The I/O model is a set of queued messages.  Protocol drivers
-	submit one or more <structname>struct spi_message</structname>
-	objects, which are processed and completed asynchronously.
-	(There are synchronous wrappers, however.)  Messages are
-	built from one or more <structname>struct spi_transfer</structname>
-	objects, each of which wraps a full duplex SPI transfer.
-	A variety of protocol tweaking options are needed, because
-	different chips adopt very different policies for how they
-	use the bits transferred with SPI.

-	I<superscript>2</superscript>C (or without fancy typography, "I2C")
-	is an acronym for the "Inter-IC" bus, a simple bus protocol which is
-	widely used where low data rate communications suffice.
-	Since it's also a licensed trademark, some vendors use another
-	name (such as "Two-Wire Interface", TWI) for the same bus.
-	I2C only needs two signals (SCL for clock, SDA for data), conserving
-	board real estate and minimizing signal quality issues.
-	Most I2C devices use seven bit addresses, and bus speeds of up
-	to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
-	found wide use.
-	I2C is a multi-master bus; open drain signaling is used to
-	arbitrate between masters, as well as to handshake and to
-	synchronize clocks from slower clients.
-     </para>
-
-     <para>
-	The Linux I2C programming interfaces support only the master
-	side of bus interactions, not the slave side.
-	The programming interface is structured around two kinds of driver,
-	and two kinds of device.
-	An I2C "Adapter Driver" abstracts the controller hardware; it binds
-	to a physical device (perhaps a PCI device or platform_device) and
-	exposes a <structname>struct i2c_adapter</structname> representing
-	each I2C bus segment it manages.
-	On each I2C bus segment will be I2C devices represented by a
-	<structname>struct i2c_client</structname>.  Those devices will
-	be bound to a <structname>struct i2c_driver</structname>,
-	which should follow the standard Linux driver model.
-	(At this writing, a legacy model is more widely used.)
-	There are functions to perform various I2C protocol operations; at
-	this writing all such functions are usable only from task context.
-     </para>
-
-     <para>
-	The System Management Bus (SMBus) is a sibling protocol.  Most SMBus
-	systems are also I2C conformant.  The electrical constraints are
-	tighter for SMBus, and it standardizes particular protocol messages
-	and idioms.  Controllers that support I2C can also support most
-	SMBus operations, but SMBus controllers don't support all the protocol
-	options that an I2C controller will.
-	There are functions to perform various SMBus protocol operations,
-	either using I2C primitives or by issuing SMBus commands to
-	i2c_adapter devices which don't support those I2C operations.

-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

-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?

-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
