+/** A note about RMI4 F11 register structure.
+ *
+ * The properties for
+ * a given sensor are described by its query registers.  The number of query
+ * registers and the layout of their contents are described by the F11 device
+ * queries as well as the sensor query information.
+ *
+ * Similarly, each sensor has control registers that govern its behavior.  The
+ * size and layout of the control registers for a given sensor can be determined
+ * by parsing that sensors query registers.
+ *
+ * And in a likewise fashion, each sensor has data registers where it reports
+ * its touch data and other interesting stuff.  The size and layout of a
+ * sensors data registers must be determined by parsing its query registers.
+ *
+ * The short story is that we need to read and parse a lot of query
+ * registers in order to determine the attributes of a sensor. Then
+ * we need to use that data to compute the size of the control and data
+ * registers for sensor.
+ *
+ * The end result is that we have a number of structs that aren't used to
+ * directly generate the input events, but their size, location and contents
+ * are critical to determining where the data we are interested in lives.
+ *
+ * At this time, the driver does not yet comprehend all possible F11
+ * configuration options, but it should be sufficient to cover 99% of RMI4 F11
+ * devices currently in the field.

+	  Most LCDs use a standard controller which supports hardware lines of 40

+	  and is the case for most parallel LCDs. Other LCDs, and some serial ones,
+	  however, use the same line width internally as what is visible. The KS0074
+	  for example, uses 16 characters per line for 16 visible characters per line.

+	  Most LCDs use a single address bit to differentiate line 0 and line 1. Since
+	  some of them need to be able to address 40 chars with the lower bits, they

+ * Author:
+ *   Jake Oshins <jakeo@microsoft.com>
+ *
+ * This driver acts as a paravirtual front-end for PCI Express root buses.
+ * When a PCI Express function (either an entire device or an SR-IOV
+ * Virtual Function) is being passed through to the VM, this driver exposes
+ * a new bus to the guest VM.  This is modeled as a root PCI bus because
+ * no bridges are being exposed to the VM.  In fact, with a "Generation 2"
+ * VM within Hyper-V, there may seem to be no PCI bus at all in the VM
+ * until a device as been exposed using this driver.
+ *
+ * Each root PCI bus has its own PCI domain, which is called "Segment" in
+ * the PCI Firmware Specifications.  Thus while each device passed through
+ * to the VM using this front-end will appear at "device 0", the domain will
+ * be unique.  Typically, each bus will have one PCI function on it, though
+ * this driver does support more than one.
+ *
+ * In order to map the interrupts from the device through to the guest VM,
+ * this driver also implements an IRQ Domain, which handles interrupts (either
+ * MSI or MSI-X) associated with the functions on the bus.  As interrupts are
+ * set up, torn down, or reaffined, this driver communicates with the
+ * underlying hypervisor to adjust the mappings in the I/O MMU so that each
+ * interrupt will be delivered to the correct virtual processor at the right
+ * vector.  This driver does not support level-triggered (line-based)
+ * interrupts, and will report that the Interrupt Line register in the
+ * function's configuration space is zero.
+ *
+ * The rest of this driver mostly maps PCI concepts onto underlying Hyper-V
+ * facilities.  For instance, the configuration space of a function exposed
+ * by Hyper-V is mapped into a single page of memory space, and the
+ * read and write handlers for config space must be aware of this mechanism.
+ * Similarly, device setup and teardown involves messages sent to and from
+ * the PCI back-end driver in Hyper-V.

-Description: Measurement Computing PCIM-DDA06-16
-Devices: [Measurement Computing] PCIM-DDA06-16 (cb_pcimdda)
-Author: Calin Culianu <calin@ajvar.org>
-Updated: Mon, 14 Apr 2008 15:15:51 +0100
-Status: works
-
-All features of the PCIM-DDA06-16 board are supported.  This board
-has 6 16-bit AO channels, and the usual 8255 DIO setup.  (24 channels,
-configurable in banks of 8 and 4, etc.).  This board does not support commands.
-
-The board has a peculiar way of specifying AO gain/range settings -- You have
-1 jumper bank on the card, which either makes all 6 AO channels either
-5 Volt unipolar, 5V bipolar, 10 Volt unipolar or 10V bipolar.
-
-Since there is absolutely _no_ way to tell in software how this jumper is set
-(well, at least according  to the rather thin spec. from Measurement Computing
- that comes with the board), the driver assumes the jumper is at its factory
-default setting of +/-5V.
-
-Also of note is the fact that this board features another jumper, whose
-state is also completely invisible to software.  It toggles two possible AO
-output modes on the board:
-
-  - Update Mode: Writing to an AO channel instantaneously updates the actual
-    signal output by the DAC on the board (this is the factory default).
-  - Simultaneous XFER Mode: Writing to an AO channel has no effect until
-    you read from any one of the AO channels.  This is useful for loading
-    all 6 AO values, and then reading from any one of the AO channels on the
-    device to instantly update all 6 AO values in unison.  Useful for some
-    control apps, I would assume?  If your jumper is in this setting, then you
-    need to issue your comedi_data_write()s to load all the values you want,
-    then issue one comedi_data_read() on any channel on the AO subdevice
-    to initiate the simultaneous XFER.

- *      In the original out of kernel Digi dgap driver, firmware
- *      loading was done via user land to driver handshaking.
- *
- *      For cards that support a concentrator (port expander),
- *      I believe the concentrator its self told the card which
- *      concentrator is actually attached and then that info
- *      was used to tell user land which concentrator firmware
- *      image was to be downloaded. I think even the BIOS or
- *      FEP images required could change with the connection
- *      of a particular concentrator.
- *
- *      Since I have no access to any of these cards or
- *      concentrators, I cannot put the correct concentrator
- *      firmware file names into the firmware_info structure
- *      as is now done for the BIOS and FEP images.
- *
- *      I think, but am not certain, that the cards supporting
- *      concentrators will function without them. So support
- *      of these cards has been left in this driver.
- *
- *      In order to fully support those cards, they would
- *      either have to be acquired for dissection or maybe
- *      Digi International could provide some assistance.

+
+This document describes the ACT2000 driver for the
+IBM Active 2000 ISDN card.
+
+There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
+Version. Currently, only the ISA-Bus version of the card is supported.
+However MCA and PCMCIA will follow soon.
+
+The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
+manually using the DIP switches.
+
+Setting up the DIP switches for the IBM Active 2000 ISDN card:
+
+	 Note: S5 and S6 always set off!
+
+     S1  S2  S3  S4  Base-port
+     on  on  on  on  0x0200 (Factory default)
+     off on  on  on  0x0240 
+     on  off on  on  0x0280 
+     off off on  on  0x02c0

+     on  on  off off 0xcee0 
+     off on  off off 0xcea0 
+     on  off off off 0xce60 
+     off off off off Card disabled 
+
+IRQ is configured by software. Possible values are:
+
+  3, 5, 7, 10, 11, 12, 15 and none (polled mode)
+
+
+The ACT2000 driver may either be built into the kernel or as a module.
+Initialization depends on how the driver is built:
+
+Driver built into the kernel:
+
+  The ACT2000 driver can be configured using the commandline-feature while
+  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
+
+  act2000=b,p,i[,idstring]
+
+  where
+
+    b = Bus-Type      (1=ISA, 2=MCA, 3=PCMCIA)
+    p = portbase      (-1 means autoprobe)
+    i = Interrupt     (-1 means use next free IRQ, 0 means polled mode)
+
+  The idstring is an arbitrary string used for referencing the card
+  by the actctrl tool later.
+
+  Defaults used, when no parameters given at all:
+
+    1,-1,-1,""
+
+  which means: Autoprobe for an ISA card, use next free IRQ, let the
+  ISDN linklevel fill the IdString (usually "line0" for the first card).
+ 
+  If you like to use more than one card, you can use the program
+  "actctrl" from the utility-package to configure additional cards.
+
+  Using the "actctrl"-utility, portbase and irq can also be changed
+  during runtime. The D-channel protocol is configured by the "dproto"
+  option of the "actctrl"-utility after loading the firmware into the
+  card's memory using the "actctrl"-utility.
+
+Driver built as module:
+
+  The module act2000.o can be configured during modprobe (insmod) by
+  appending its parameters to the modprobe resp. insmod commandline.
+  The following syntax is accepted:
+
+    act_bus=b act_port=p act_irq=i act_id=idstring
+
+  where b, p, i and idstring have the same meanings as the parameters
+  described for the builtin version above.
+
+  Using the "actctrl"-utility, the same features apply to the modularized
+  version as to the kernel-builtin one. (i.e. loading of firmware and
+  configuring the D-channel protocol)
+
+Loading the firmware into the card:
+
+  The firmware is supplied together with the isdn4k-utils package. It
+  can be found in the subdirectory act2000/firmware/
+
+  Assuming you have installed the utility-package correctly, the firmware
+  will be downloaded into the card using the following command:
+
+    actctrl -d idstring load /etc/isdn/bip11.btl
+
+  where idstring is the Name of the card, given during insmod-time or
+  (for kernel-builtin driver) on the kernel commandline. If only one
+  ISDN card is used, the -d isdstrin may be omitted.
+
+  For further documentation (adding more IBM Active 2000 cards), refer to
+  the manpage actctrl.8 which is included in the isdn4k-utils package.

+
+The card communicates with the PC by two interfaces:
+  1. A range of 4 successive port-addresses, whose base address can be 
+     configured with the switches.
+  2. A memory window with 16KB-256KB size, which can be setup in 16k steps
+     over the whole range of 16MB. Isdn4linux only uses a 16k window.
+     The base address of the window can be configured when loading
+     the lowlevel-module (see README). If using more than one card,
+     all cards are mapped to the same window and activated as needed.
+
+Setting up the IO-address dipswitches for the ICN-ISDN-card:
+
+  Two types of cards exist, one with dip-switches and one with

+The ICN driver may be built into the kernel or as a module. Initialization
+depends on how the driver is built:
+
+Driver built into the kernel:
+
+  The ICN driver can be configured using the commandline-feature while
+  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
+
+  icn=p,m[,idstring1[,idstring2]]
+
+  where
+
+    p = portbase      (default: 0x320)
+    m = shared memory (default: 0xd0000)
+
+  When using the ICN double card (4B), you MUST define TWO idstrings.
+  idstring must start with a character! There is no way for the driver
+  to distinguish between a 2B and 4B type card. Therefore, by supplying
+  TWO idstrings, you tell the driver that you have a 4B installed.
+  
+  If you like to use more than one card, you can use the program
+  "icnctrl" from the utility-package to configure additional cards.
+  You need to configure shared memory only once, since the icn-driver
+  maps all cards into the same address-space.
+
+  Using the "icnctrl"-utility, portbase and shared memory can also be
+  changed during runtime.
+
+  The D-channel protocol is configured by loading different firmware
+  into the card's memory using the "icnctrl"-utility.
+
+
+Driver built as module:
+
+  The module icn.o can be configured during "insmod'ing" it by
+  appending its parameters to the insmod-commandline. The following
+  syntax is accepted:
+
+    portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
+
+  where p, m, idstring1 and idstring2 have the same meanings as the
+  parameters described for the kernel-version above.
+      
+  When using the ICN double card (4B), you MUST define TWO idstrings.
+  idstring must start with a character! There is no way for the driver
+  to distinguish between a 2B and 4B type card. Therefore, by supplying
+  TWO idstrings, you tell the driver that you have a 4B installed.
+

+  version like to the kernel-builtin one.
+
+  The D-channel protocol is configured by loading different firmware
+  into the card's memory using the "icnctrl"-utility.
+
+Loading the firmware into the card:
+
+  The firmware is supplied together with the isdn4k-utils package. It
+  can be found in the subdirectory icnctrl/firmware/
+
+  There are 3 files:
+
+    loadpg.bin   - Image of the bootstrap loader.
+    pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
+    pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
+
+  Assuming you have installed the utility-package correctly, the firmware
+  will be downloaded into the 2B-card using the following command:
+
+    icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
+
+  where XX is either "1t" or "eu", depending on the D-Channel protocol
+  used on your S0-bus and Idstring is the Name of the card, given during
+  insmod-time or (for kernel-builtin driver) on the kernel commandline.
+
+  To load a 4B-card, the same command is used, except a second firmware
+  file is appended to the commandline of icnctrl.
+
+  -> After downloading firmware, the two LEDs at the back cover of the card
+     (ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
+     is up, the corresponding led is lit continuously.
+
+  For further documentation (adding more ICN-cards), refer to the manpage
+  icnctrl.8 which is included in the isdn4k-utils package.

+ README file for the PCBIT-D Device Driver.
+------------------------------------------------------------------------------
+
+The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
+developed in cooperation with Portugal Telecom and Inesc.
+The driver interfaces with the standard kernel isdn facilities
+originally developed by Fritz Elfert in the isdn4linux project.
+
+The common versions of the pcbit board require a firmware that is 
+distributed (and copyrighted) by the manufacturer. To load this
+firmware you need "pcbitctl" available on the standard isdn4k-utils
+package or in the pcbit package available in:
+
+ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
+
+Known Limitations:
+
+- The board reset procedure is at the moment incorrect and will only
+allow you to load the firmware after a hard reset.
+
+- Only HDLC in B-channels is supported at the moment. There is no
+current support for X.25 in B or D channels nor LAPD in B
+channels. The main reason is that these two other protocol modes have,
+to my knowledge, very little use. If you want to see them implemented
+*do* send me a mail.
+
+- The driver often triggers errors in the board that I and the
+manufacturer believe to be caused by bugs in the firmware. The current
+version includes several procedures for error recovery that should
+allow normal operation. Plans for the future include cooperation with
+the manufacturer in order to solve this problem.
+
+Information/hints/help can be obtained in the linux isdn
+mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me.
+
+regards,
+  Pedro.

+1. Introduction
+---------------
+
+The revision 2 Linux driver for SpellCaster ISA ISDN adapters is built
+upon ISDN4Linux available separately or as included in Linux 2.0 and later.
+The driver will support a maximum of 4 adapters in any one system of any
+type including DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI for a
+maximum of 92 channels for host. The driver is supplied as a module in
+source form and needs to be complied before it can be used. It has been
+tested on Linux 2.0.20.
+
+1.1 What Is ISDN4Linux
+
+ISDN4Linux is a driver and set of tools used to access and use ISDN devices
+on a Linux platform in a common and standard way. It supports HDLC and PPP
+protocols and offers channel bundling and MLPPP support. To use ISDN4Linux
+you need to configure your kernel for ISDN support and get the ISDN4Linux
+tool kit from our web site.
+
+ISDN4Linux creates a channel pool from all of the available ISDN channels
+and therefore can function across adapters. When an ISDN4Linux compliant
+driver (such as ours) is loaded, all of the channels go into a pool and
+are used on a first-come first-served basis. In addition, individual
+channels can be specifically bound to particular interfaces.
+
+1.2 What is different between this driver and previous drivers?
+
+The revision 2 driver besides adopting the ISDN4Linux architecture has many
+subtle and not so subtle functional differences from previous releases. These
+include:
+	- More efficient shared memory management combined with a simpler
+	  configuration. All adapters now use only 16Kbytes of shared RAM
+	  versus between 16K and 64K. New methods for using the shared RAM
+	  allow us to utilize all of the available RAM on the adapter through
+	  only one 16K page.
+	- Better detection of available upper memory. The probing routines
+	  have been improved to better detect available shared RAM pages and
+	  used pages are now locked.
+	- Decreased loading time and a wider range of I/O ports probed.
+	  We have significantly reduced the amount of time it takes to load
+	  the driver and at the same time doubled the number of I/O ports
+	  probed increasing the likelihood of finding an adapter.
+	- We now support all ISA adapter models with a single driver instead
+	  of separate drivers for each model. The revision 2 driver supports
+	  the DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI in any
+	  combination up to a maximum of four adapters per system.
+	- On board PPP protocol support has been removed in favour of the
+	  sync-PPP support used in ISDN4Linux. This means more control of
+	  the protocol parameters, faster negotiation time and a more
+	  familiar interface.
+
+1.3 How do I setup my system with the correct software to use
+    this driver release?
+
+Before you can compile, install and use the SpellCaster ISA ISDN driver, you
+must ensure that the following software is installed, configured and running:
+
+	- Linux kernel 2.0.20 or later with the required init and ps
+	  versions. Please see your distribution vendor for the correct
+	  utility packages. The latest kernel is available from
+	  ftp://sunsite.unc.edu/pub/Linux/kernel/v2.0/
+
+	- The latest modules package (modules-2.0.0.tar.gz) from
+	  ftp://sunsite.unc.edu/pub/Linux/kernel/modules-2.0.0.tar.gz
+
+	- The ISDN4Linux tools available from 
+	  ftp://ftp.franken.de/pub/isdn4linux/v2.0/isdn4k-utils-2.0.tar.gz
+	  This package may fail to compile for you so you can alternatively
+	  get a pre-compiled version from
+	  ftp://ftp.spellcast.com/pub/drivers/isdn4linux/isdn4k-bin-2.0.tar.gz
+
+
+2. Basic Operations
+-------------------
+
+2.1 Unpacking and installing the driver
+
+	1. As root, create a directory in a convenient place. We suggest
+	   /usr/src/spellcaster.
+	
+	2. Unpack the archive with :
+		tar xzf sc-n.nn.tar.gz -C /usr/src/spellcaster
+	
+	3. Change directory to /usr/src/spellcaster
+
+	4. Read the README and RELNOTES files.
+
+	5. Run 'make' and if all goes well, run 'make install'.
+
+2.2 Read the man pages!!!
+
+Make sure you read the scctrl(8) and sc(4) manual pages before continuing
+any further. Type 'man 8 scctrl' and 'man 4 sc'.
+
+2.3 Installing the driver
+
+To install the driver, type '/sbin/insmod sc' as root. sc(4) details options
+you can specify but you shouldn't need to use any unless this doesn't work.
+
+Make sure the driver loaded and detected all of the adapters by typing
+'dmesg'.
+
+The driver can be configured so that it is loaded upon startup.  To do this, 
+edit the file "/etc/modules/'uname -f'/'uname -v'" and insert the driver name
+"sc" into this file.
+
+2.4 Removing the driver
+
+To remove the driver, delete any interfaces that may exist (see isdnctrl(8)
+for more on this) and then type '/sbin/rmmod sc'.
+
+2.5 What to do if it doesn't load
+
+If, when you try to install the driver, you get a message mentioning
+'register_isdn' then you do not have the ISDN4Linux system installed. Please
+make sure that ISDN support is configured in the kernel.
+
+If you get a message that says 'initialization of sc failed', then the
+driver failed to detect an adapter or failed to find resources needed such
+as a free IRQ line or shared memory segment. If you are sure there are free
+resources available, use the insmod options detailed in sc(4) to override
+the probing function.  
+
+Upon testing, the following problem was noted, the driver would load without
+problems, but the board would not respond beyond that point.  When a check was 
+done with 'cat /proc/interrupts' the interrupt count for sc was 0.  In the event 
+of this problem, change the BIOS settings so that the interrupts in question are
+reserved for ISA use only.   
+
+
+2.6 How to setup ISDN4Linux with the driver
+
+There are three main configurations which you can use with the driver:
+
+A)	Basic HDLC connection
+B)	PPP connection
+C)	MLPPP connection
+
+It should be mentioned here that you may also use a tty connection if you
+desire. The Documentation directory of the isdn4linux subsystem offers good
+documentation on this feature.
+
+A) 10 steps to the establishment of a basic HDLC connection
+-----------------------------------------------------------
+
+- please open the isdn-hdlc file in the examples directory and follow along...
+	
+	This file is a script used to configure a BRI ISDN TA to establish a 
+	basic HDLC connection between its two channels.  Two network 
+	interfaces are created and two routes added between the channels.
+
+	i)   using the isdnctrl utility, add an interface with "addif" and 
+	     name it "isdn0"
+	ii)  add the outgoing and inbound telephone numbers
+	iii) set the Layer 2 protocol to hdlc
+	iv)  set the eaz of the interface to be the phone number of that 
+	     specific channel
+	v)   to turn the callback features off, set the callback to "off" and
+	     the callback delay (cbdelay) to 0.
+	vi)  the hangup timeout can be set to a specified number of seconds
+	vii) the hangup upon incoming call can be set on or off 
+	viii) use the ifconfig command to bring up the network interface with 
+	      a specific IP address and point to point address
+	ix)  add a route to the IP address through the isdn0 interface
+	x)   a ping should result in the establishment of the connection
+
+	
+B) Establishment of a PPP connection
+------------------------------------
+
+- please open the isdn-ppp file in the examples directory and follow along...
+	
+	This file is a script used to configure a BRI ISDN TA to establish a 
+	PPP connection 	between the two channels.  The file is almost 
+	identical to the HDLC connection example except that the packet 
+	encapsulation type has to be set.
+	
+	use the same procedure as in the HDLC connection from steps i) to 
+	iii) then, after the Layer 2 protocol is set, set the encapsulation 
+	"encap" to syncppp. With this done, the rest of the steps, iv) to x) 
+	can be followed from above.
+
+	Then, the ipppd (ippp daemon) must be setup:
+	
+	xi)   use the ipppd function found in /sbin/ipppd to set the following:
+	xii)  take out (minus) VJ compression and bsd compression
+	xiii) set the mru size to 2000
+	xiv)  link the two /dev interfaces to the daemon
+
+NOTE:  A "*" in the inbound telephone number specifies that a call can be 
+accepted on any number.
+
+C) Establishment of a MLPPP connection
+--------------------------------------
+
+- please open the isdn-mppp file in the examples directory and follow along...
+	
+	This file is a script used to configure a BRI ISDN TA to accept a 
+	Multi Link PPP connection. 
+	
+	i)   using the isdnctrl utility, add an interface with "addif" and 
+	     name it "ippp0"
+	ii)  add the inbound telephone number
+	iii) set the Layer 2 protocol to hdlc and the Layer 3 protocol to 
+	     trans (transparent)
+	iv)  set the packet encapsulation to syncppp
+	v)   set the eaz of the interface to be the phone number of that 
+	     specific channel
+	vi)  to turn the callback features off, set the callback to "off" and
+	     the callback delay (cbdelay) to 0.
+	vi)  the hangup timeout can be set to a specified number of seconds
+	vii) the hangup upon incoming call can be set on or off 
+	viii) add a slave interface and name it "ippp32" for example
+	ix)  set the similar parameters for the ippp32 interface
+	x)   use the ifconfig command to bring-up the ippp0 interface with a 
+	     specific IP address and point to point address
+	xi)  add a route to the IP address through the ippp0 interface
+	xii) use the ipppd function found in /sbin/ipppd to set the following:
+	xiii) take out (minus) bsd compression
+	xiv) set the mru size to 2000
+	xv)  add (+) the multi-link function "+mp"
+	xvi)  link the two /dev interfaces to the daemon
+
+NOTE:  To use the MLPPP connection to dial OUT to a MLPPP connection, change 
+the inbound telephone numbers to the outgoing telephone numbers of the MLPPP 
+host.
+
+	
+3. Beta Change Summaries and Miscellaneous Notes
+------------------------------------------------
+When using the "scctrl" utility to upload firmware revisions on the board,
+please note that the byte count displayed at the end of the operation may be
+different from the total number of bytes in the "dcbfwn.nn.sr" file. Please
+disregard the displayed byte count.
+
+It was noted that in Beta Release 1, the module would fail to load and result
+in a segmentation fault when 'insmod'ed. This problem was created when one of
+the isdn4linux parameters, (isdn_ctrl, data field) was filled in. In some
+cases, this data field was NULL, and was left unchecked, so when it was
+referenced... segv. The bug has been fixed around line 63-68 of event.c.

-	  is accessible through the /dev/lcd char device (10, 156), and the
-	  keypad through /dev/keypad (10, 185). Both require misc device to be
-	  enabled. This code can either be compiled as a module, or linked into

-	  is about, say N.
-
-config PANEL_PARPORT

-	range 0 255
-	default "0"
-	---help---
-	  This is the index of the parallel port the panel is connected to. One
-	  driver instance only supports one parallel port, so if your keypad
-	  and LCD are connected to two separate ports, you have to start two

-	    4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad
-	    5 = 2x40 parallel LCD (old one), with old keypad
-

-	  for example, uses 16 characters per line for 16 visible characters per line.

-	---help---
-	  This driver now supports any serial or parallel LCD wired to a parallel
-	  port. But before assigning signals, the driver needs to know if it will
-	  be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
-	  (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals

+ *      RcvArray entries.
+ *   2. List of partially used groups - tid_used_list
+ *      This list contains sets of RcvArray entries which are
+ *      not completely used up. Another mapping request could
+ *      use some of all of the remaining entries.
+ *   3. List of full groups - tid_full_list
+ *      This is the list where sets that are completely used
+ *      up go.
+ *
+ * An attempt to optimize the usage of RcvArray entries is
+ * made by finding all sets of physically contiguous pages in a
+ * user's buffer.
+ * These physically contiguous sets are further split into
+ * sizes supported by the receive engine of the HFI. The
+ * resulting sets of pages are stored in struct tid_pageset,
+ * which describes the sets as:
+ *    * .count - number of pages in this set
+ *    * .idx - starting index into struct page ** array
+ *                    of this set
+ *
+ * From this point on, the algorithm deals with the page sets
+ * described above. The number of pagesets is divided by the
+ * RcvArray group size to produce the number of full groups
+ * needed.
+ *
+ * Groups from the 3 lists are manipulated using the following
+ * rules:
+ *   1. For each set of 8 pagesets, a complete group from
+ *      tid_group_list is taken, programmed, and moved to
+ *      the tid_full_list list.
+ *   2. For all remaining pagesets:
+ *      2.1 If the tid_used_list is empty and the tid_group_list
+ *          is empty, stop processing pageset and return only
+ *          what has been programmed up to this point.
+ *      2.2 If the tid_used_list is empty and the tid_group_list
+ *          is not empty, move a group from tid_group_list to
+ *          tid_used_list.
+ *      2.3 For each group is tid_used_group, program as much as
+ *          can fit into the group. If the group becomes fully
+ *          used, move it to tid_full_list.

- * dwc2_hc_start_transfer() - Does the setup for a data transfer for a host
- * channel and starts the transfer
- *
- * @hsotg: Programming view of DWC_otg controller
- * @chan:  Information needed to initialize the host channel. The xfer_len value
- *         may be reduced to accommodate the max widths of the XferSize and
- *         PktCnt fields in the HCTSIZn register. The multi_count value may be
- *         changed to reflect the final xfer_len value.
- *
- * This function may be called in either Slave mode or DMA mode. In Slave mode,
- * the caller must ensure that there is sufficient space in the request queue
- * and Tx Data FIFO.
- *
- * For an OUT transfer in Slave mode, it loads a data packet into the
- * appropriate FIFO. If necessary, additional data packets are loaded in the
- * Host ISR.
- *
- * For an IN transfer in Slave mode, a data packet is requested. The data
- * packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
- * additional data packets are requested in the Host ISR.
- *
- * For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
- * register along with a packet count of 1 and the channel is enabled. This
- * causes a single PING transaction to occur. Other fields in HCTSIZ are
- * simply set to 0 since no data transfer occurs in this case.
- *
- * For a PING transfer in DMA mode, the HCTSIZ register is initialized with
- * all the information required to perform the subsequent data transfer. In
- * addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
- * controller performs the entire PING protocol, then starts the data
- * transfer.

+ * reservation point of view it's assumed that the schedule goes right back to
+ * the beginning after the end of the schedule.
+ *
+ * What does that mean for scheduling things with a long interval?  It means
+ * we'll reserve time for them in every possible microframe that they could
+ * ever be scheduled in.  ...but we'll still only actually schedule them as
+ * often as they were requested.
+ *
+ * We keep our schedule in a "bitmap" structure.  This simplifies having
+ * to keep track of and merge intervals: we just let the bitmap code do most
+ * of the heavy lifting.  In a way scheduling is much like memory allocation.
+ *
+ * We schedule 100us per uframe or 80% of 125us (the maximum amount you're
+ * supposed to schedule for periodic transfers).  That's according to spec.
+ *
+ * Note that though we only schedule 80% of each microframe, the bitmap that we
+ * keep the schedule in is tightly packed (AKA it doesn't have 100us worth of
+ * space for each uFrame).
+ *
+ * Requirements:
+ * - DWC2_HS_SCHEDULE_UFRAMES must even divide 0x4000 (HFNUM_MAX_FRNUM + 1)
+ * - DWC2_HS_SCHEDULE_UFRAMES must be 8 times DWC2_LS_SCHEDULE_FRAMES (probably
+ *   could be any multiple of 8 times DWC2_LS_SCHEDULE_FRAMES, but there might
+ *   be bugs).  The 8 comes from the USB spec: number of microframes per frame.

+ * Constants related to low speed scheduling
+ *
+ * For high speed we schedule every 1us.  For low speed that's a bit overkill,
+ * so we make up a unit called a "slice" that's worth 25us.  There are 40
+ * slices in a full frame and we can schedule 36 of those (90%) for periodic
+ * transfers.
+ *
+ * Our low speed schedule can be as short as 1 frame or could be longer.  When
+ * we only schedule 1 frame it means that we'll need to reserve a time every
+ * frame even for things that only transfer very rarely, so something that runs
+ * every 2048 frames will get time reserved in every frame.  Our low speed
+ * schedule can be longer and we'll be able to handle more overlap, but that
+ * will come at increased memory cost and increased time to schedule.
+ *
+ * Note: one other advantage of a short low speed schedule is that if we mess
+ * up and miss scheduling we can jump in and use any of the slots that we
+ * happened to reserve.
+ *
+ * With 25 us per slice and 1 frame in the schedule, we only need 4 bytes for
+ * the schedule.  There will be one schedule per TT.

+ *
+ * @map:             The bitmap representing the schedule; will be updated
+ *                   upon success.
+ * @bits_per_period: The schedule represents several periods.  This is how many
+ *                   bits are in each period.  It's assumed that the beginning
+ *                   of the schedule will repeat after its end.
+ * @periods_in_map:  The number of periods in the schedule.
+ * @num_bits:        The number of bits we need per period we want to reserve
+ *                   in this function call.
+ * @interval:        How often we need to be scheduled for the reservation this
+ *                   time.  1 means every period.  2 means every other period.
+ *                   ...you get the picture?
+ * @start:           The bit number to start at.  Normally 0.  Must be within
+ *                   the interval or we return failure right away.
+ * @only_one_period: Normally we'll allow picking a start anywhere within the
+ *                   first interval, since we can still make all repetition
+ *                   requirements by doing that.  However, if you pass true
+ *                   here then we'll return failure if we can't fit within
+ *                   the period that "start" is in.
+ *
+ * The idea here is that we want to schedule time for repeating events that all
+ * want the same resource.  The resource is divided into fixed-sized periods
+ * and the events want to repeat every "interval" periods.  The schedule
+ * granularity is one bit.
+ *
+ * To keep things "simple", we'll represent our schedule with a bitmap that
+ * contains a fixed number of periods.  This gets rid of a lot of complexity
+ * but does mean that we need to handle things specially (and non-ideally) if
+ * the number of the periods in the schedule doesn't match well with the
+ * intervals that we're trying to schedule.
+ *
+ * Here's an explanation of the scheme we'll implement, assuming 8 periods.
+ * - If interval is 1, we need to take up space in each of the 8
+ *   periods we're scheduling.  Easy.
+ * - If interval is 2, we need to take up space in half of the
+ *   periods.  Again, easy.
+ * - If interval is 3, we actually need to fall back to interval 1.
+ *   Why?  Because we might need time in any period.  AKA for the
+ *   first 8 periods, we'll be in slot 0, 3, 6.  Then we'll be
+ *   in slot 1, 4, 7.  Then we'll be in 2, 5.  Then we'll be back to
+ *   0, 3, and 6.  Since we could be in any frame we need to reserve
+ *   for all of them.  Sucks, but that's what you gotta do.  Note that
+ *   if we were instead scheduling 8 * 3 = 24 we'd do much better, but
+ *   then we need more memory and time to do scheduling.
+ * - If interval is 4, easy.
+ * - If interval is 5, we again need interval 1.  The schedule will be
+ *   0, 5, 2, 7, 4, 1, 6, 3, 0
+ * - If interval is 6, we need interval 2.  0, 6, 4, 2.
+ * - If interval is 7, we need interval 1.
+ * - If interval is 8, we need interval 8.
+ *
+ * If you do the math, you'll see that we need to pretend that interval is
+ * equal to the greatest_common_divisor(interval, periods_in_map).
+ *
+ * Note that at the moment this function tends to front-pack the schedule.
+ * In some cases that's really non-ideal (it's hard to schedule things that
+ * need to repeat every period).  In other cases it's perfect (you can easily
+ * schedule bigger, less often repeating things).
+ *
+ * Here's the algorithm in action (8 periods, 5 bits per period):

+	 *   we do two transfers in the same frame.
+	 * - Some misses are expected.  Specifically, in order to work
+	 *   perfectly dwc2 really needs quite spectacular interrupt latency
+	 *   requirements.  It needs to be able to handle its interrupts
+	 *   completely within 125 us of them being asserted. That not only
+	 *   means that the dwc2 interrupt handler needs to be fast but it
+	 *   means that nothing else in the system has to block dwc2 for a long
+	 *   time.  We can help with the dwc2 parts of this, but it's hard to

-PRELIMINARY DRAFT, MAY CONTAIN MISTAKES!
-28 Jun 2011
-
-The USB/IP protocol follows a server/client architecture. The server exports the
-USB devices and the clients imports them. The device driver for the exported
-USB device runs on the client machine.
-
-The client may ask for the list of the exported USB devices. To get the list the
-client opens a TCP/IP connection towards the server, and sends an OP_REQ_DEVLIST
-packet on top of the TCP/IP connection (so the actual OP_REQ_DEVLIST may be sent
-in one or more pieces at the low level transport layer). The server sends back
-the OP_REP_DEVLIST packet which lists the exported USB devices. Finally the
-TCP/IP connection is closed.
-
- virtual host controller                                 usb host
-      "client"                                           "server"

-Once the client knows the list of exported USB devices it may decide to use one
-of them. First the client opens a TCP/IP connection towards the server and
-sends an OP_REQ_IMPORT packet. The server replies with OP_REP_IMPORT. If the
-import was successful the TCP/IP connection remains open and will be used
-to transfer the URB traffic between the client and the server. The client may
-send two types of packets: the USBIP_CMD_SUBMIT to submit an URB, and
-USBIP_CMD_UNLINK to unlink a previously submitted URB. The answers of the
-server may be USBIP_RET_SUBMIT and USBIP_RET_UNLINK respectively.

+ *
+ * ARM SBSA Generic Watchdog has two stage timeouts:
+ * the first signal (WS0) is for alerting the system by interrupt,
+ * the second one (WS1) is a real hardware reset.
+ * More details about the hardware specification of this device:
+ * ARM DEN0029B - Server Base System Architecture (SBSA)
+ *
+ * This driver can operate ARM SBSA Generic Watchdog as a single stage watchdog
+ * or a two stages watchdog, it's set up by the module parameter "action".
+ * In the single stage mode, when the timeout is reached, your system
+ * will be reset by WS1. The first signal (WS0) is ignored.
+ * In the two stages mode, when the timeout is reached, the first signal (WS0)
+ * will trigger panic. If the system is getting into trouble and cannot be reset
+ * by panic or restart properly by the kdump kernel(if supported), then the
+ * second stage (as long as the first stage) will be reached, system will be
+ * reset by WS1. This function can help administrator to backup the system
+ * context info by panic console output or kdump.
+ *
+ * SBSA GWDT:
+ * if action is 1 (the two stages mode):
+ * |--------WOR-------WS0--------WOR-------WS1
+ * |----timeout-----(panic)----timeout-----reset
+ *
+ * if action is 0 (the single stage mode):
+ * |------WOR-----WS0(ignored)-----WOR------WS1
+ * |--------------timeout-------------------reset
+ *
+ * Note: Since this watchdog timer has two stages, and each stage is determined
+ * by WOR, in the single stage mode, the timeout is (WOR * 2); in the two
+ * stages mode, the timeout is WOR. The maximum timeout in the two stages mode
+ * is half of that in the single stage mode.
