+     <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.

+  <chapter id="i2c">
+     <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.

-     <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

-      <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.

+Another feature of the driver is misc device called "freefall" that
