+                        ACPI Debug Output
+The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
+output.  This document describes how to use this facility.
+Compile-time configuration
+--------------------------
+ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG.  If this config
+option is turned off, the debug messages are not even built into the
+kernel.
+Boot- and run-time configuration
+--------------------------------
+When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
+you're interested in.  At boot-time, use the acpi.debug_layer and
+acpi.debug_level kernel command line options.  After boot, you can use the
+debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
+the debug messages.
+debug_layer (component)
+-----------------------
+The "debug_layer" is a mask that selects components of interest, e.g., a
+specific driver or part of the ACPI interpreter.  To build the debug_layer
+bitmask, look for the "#define _COMPONENT" in an ACPI source file.
+You can set the debug_layer mask at boot-time using the acpi.debug_layer
+command line argument, and you can change it after boot by writing values
+to /sys/module/acpi/parameters/debug_layer.

+debug_level
+-----------
+The "debug_level" is a mask that selects different types of messages, e.g.,
+those related to initialization, method execution, informational messages, etc.
+To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
+statement.
+The ACPI interpreter uses several different levels, but the Linux
+ACPI core and ACPI drivers generally only use ACPI_LV_INFO.
+You can set the debug_level mask at boot-time using the acpi.debug_level
+command line argument, and you can change it after boot by writing values
+to /sys/module/acpi/parameters/debug_level.
+The possible levels are defined in include/acpi/acoutput.h.  Reading
+/sys/module/acpi/parameters/debug_level shows the supported mask values,
+currently these:
+    ACPI_LV_INIT                    0x00000001

+To turn on this message, set the ACPI_BUS_COMPONENT bit in acpi.debug_layer
+and the ACPI_LV_INFO bit in acpi.debug_level.  (The ACPI_DEBUG_PRINT

-Go high for approx 8T (Around 4000us)
-Go low for less than 2T (Around 750us)
-For each of the 32 bits

-  Go high for less than T (Around 400us) == 0
-  Go low for less than 2T (Around 750us)
-Rather than repeat a signal when the button is held down certain buttons
-generate the following code to indicate repetition.
-Go low for approx 16T
-Go high for approx 4T
-Go low for less than 2T
-(By removing the <2T from the start of the sequence and placing at the end

+Overview
+--------
+This driver implements the support for Linux of Silicon Labs (Silabs)
+C2 Interface used for in-system programming of micro controllers.
+By using this driver you can reprogram the in-system flash without EC2
+or EC3 debug adapter. This solution is also useful in those systems
+where the micro controller is connected via special GPIOs pins.
+References
+----------
+The C2 Interface main references are at (http://www.silabs.com)
+Silicon Laboratories site], see:
+- AN127: FLASH Programming via the C2 Interface at
+http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf, and
+- C2 Specification at
+http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf,
+however it implements a two wire serial communication protocol (bit
+banging) designed to enable in-system programming, debugging, and
+boundary-scan testing on low pin-count Silicon Labs devices. Currently
+this code supports only flash programming but extensions are easy to
+add.
+Using the driver
+----------------
+Once the driver is loaded you can use sysfs support to get C2port's
+info or read/write in-system flash.
+# ls /sys/class/c2port/c2port0/
+access            flash_block_size  flash_erase       rev_id
+dev_id            flash_blocks_num  flash_size        subsystem/
+flash_access      flash_data        reset             uevent
+Initially the C2port access is disabled since you hardware may have
+such lines multiplexed with other devices so, to get access to the
+C2port, you need the command:
+# echo 1 > /sys/class/c2port/c2port0/access
+after that you should read the device ID and revision ID of the
+connected micro controller:
+# cat /sys/class/c2port/c2port0/dev_id
+8
+# cat /sys/class/c2port/c2port0/rev_id
+1
+However, for security reasons, the in-system flash access in not
+enabled yet, to do so you need the command:
+# echo 1 > /sys/class/c2port/c2port0/flash_access
+After that you can read the whole flash:
+# cat /sys/class/c2port/c2port0/flash_data > image
+erase it:
+# echo 1 > /sys/class/c2port/c2port0/flash_erase
+and write it:
+# cat image > /sys/class/c2port/c2port0/flash_data
+after writing you have to reset the device to execute the new code:
+# echo 1 > /sys/class/c2port/c2port0/reset

-        and since it is extremely unlikely that anyone still uses one of these
-        devices, it was decided to drop it.

-What:   V4L2 dpc7146 driver
-When:   2.6.28
-Why:    Old driver for the dpc7146 demonstration board that is no longer
-        relevant. The last time this was tested on actual hardware was
-        probably around 2002. Since this is a driver for a demonstration
-        board the decision was made to remove it rather than spending a
-        lot of effort continually updating this driver to stay in sync
-        with the latest internal V4L2 or I2C API.

+Kernel driver adt7462
+======================
+Supported chips:
+  * Analog Devices ADT7462
+    Prefix: 'adt7462'
+    Addresses scanned: I2C 0x58, 0x5C
+    Datasheet: Publicly available at the Analog Devices website
+Author: Darrick J. Wong
+Description
+-----------
+This driver implements support for the Analog Devices ADT7462 chip family.
+This chip is a bit of a beast.  It has 8 counters for measuring fan speed.  It
+can also measure 13 voltages or 4 temperatures, or various combinations of the
+two.  See the chip documentation for more details about the exact set of
+configurations.  This driver does not allow one to configure the chip; that is
+left to the system designer.
+A sophisticated control system for the PWM outputs is designed into the ADT7462
+that allows fan speed to be adjusted automatically based on any of the three
+temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the ADT7462 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.  This
+feature can also be disabled for manual control of the PWM's.
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The ADT7462 will signal an ALARM if
+any measured value exceeds either limit.
+The ADT7462 samples all inputs continuously. The driver will not read
+the registers more often than once every other second. Further,
+configuration data is only read once per minute.
+Special Features
+----------------
+The ADT7462 have a 10-bit ADC and can therefore measure temperatures
+with 0.25 degC resolution.
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+The driver will report sensor labels when it is able to determine that
+information from the configuration registers.
+Configuration Notes
+-------------------
+Besides standard interfaces driver adds the following:
+* PWM Control
+* pwm#_auto_point1_pwm and temp#_auto_point1_temp and
+* pwm#_auto_point2_pwm and temp#_auto_point2_temp -
+point1: Set the pwm speed at a lower temperature bound.
+point2: Set the pwm speed at a higher temperature bound.
+The ADT7462 will scale the pwm between the lower and higher pwm speed when
+the temperature is between the two temperature boundaries.  PWM values range
+from 0 (off) to 255 (full speed).  Fan speed will be set to maximum when the
+temperature sensor associated with the PWM control exceeds temp#_max.

+have their axis automatically oriented on standard way (eg: you can directly
+play neverball).  The accelerometer data is readable via
+/sys/devices/platform/lis3lv02d.
+Sysfs attributes under /sys/devices/platform/lis3lv02d/:
+position - 3D position that the accelerometer reports. Format: "(x,y,z)"
+calibrate - read: values (x, y, z) that are used as the base for input class device operation.
+            write: forces the base to be recalibrated with the current position.
+rate - reports the sampling rate of the accelerometer device in HZ
+This driver also provides an absolute input class device, allowing
+the laptop to act as a pinball machine-esque joystick.
+Axes orientation
+----------------
+For better compatibility between the various laptops. The values reported by
+the accelerometer are converted into a "standard" organisation of the axes
+(aka "can play neverball out of the box"):
+ * When the laptop is horizontal the position reported is about 0 for X and Y
+and a positive value for Z
+ * If the left side is elevated, X increases (becomes positive)
+ * If the front side (where the touchpad is) is elevated, Y decreases (becomes negative)
+ * If the laptop is put upside-down, Z becomes negative
+If your laptop model is not recognized (cf "dmesg"), you can send an email to the
+authors to add it to the database.  When reporting a new laptop, please include
+the output of "dmidecode" plus the value of /sys/devices/platform/lis3lv02d/position
+in these four cases.

+frequency.  If spread spectrum mode is enabled, the driver also reports by what
+percent the clock signal is being spread, which should be between 0 and -0.5%.
+All frequencies are reported in KHz.

+The io_mapping functions in linux/io-mapping.h provide an abstraction for
+efficiently mapping small regions of an I/O device to the CPU. The initial
+usage is to support the large graphics aperture on 32-bit processors where
+ioremap_wc cannot be used to statically map the entire aperture to the CPU
+as it would consume too much of the kernel address space.
+A mapping object is created during driver initialization using
+        struct io_mapping *io_mapping_create_wc(unsigned long base,
+                                                unsigned long size)
+                'base' is the bus address of the region to be made
+                mappable, while 'size' indicates how large a mapping region to
+                enable. Both are in bytes.
+                This _wc variant provides a mapping which may only be used
+                with the io_mapping_map_atomic_wc or io_mapping_map_wc.
+With this mapping object, individual pages can be mapped either atomically
+or not, depending on the necessary scheduling environment. Of course, atomic
+maps are more efficient:
+        void *io_mapping_map_atomic_wc(struct io_mapping *mapping,
+                                       unsigned long offset)
+                'offset' is the offset within the defined mapping region.
+                Accessing addresses beyond the region specified in the
+                creation function yields undefined results. Using an offset
+                which is not page aligned yields an undefined result. The
+                return value points to a single page in CPU address space.
+                This _wc variant returns a write-combining map to the
+                page and may only be used with mappings created by
+                io_mapping_create_wc
+                Note that the task may not sleep while holding this page
+                mapped.
+        void io_mapping_unmap_atomic(void *vaddr)
+                'vaddr' must be the the value returned by the last
+                io_mapping_map_atomic_wc call. This unmaps the specified
+                page and allows the task to sleep once again.
+If you need to sleep while holding the lock, you can use the non-atomic
+variant, although they may be significantly slower.
+        void *io_mapping_map_wc(struct io_mapping *mapping,
+                                unsigned long offset)
+                This works like io_mapping_map_atomic_wc except it allows
+                the task to sleep while holding the page mapped.
+        void io_mapping_unmap(void *vaddr)
+                This works like io_mapping_unmap_atomic, except it is used
+                for pages mapped with io_mapping_map_wc.
+At driver close time, the io_mapping object must be freed:
+        void io_mapping_free(struct io_mapping *mapping)
+Current Implementation:
+The initial implementation of these functions uses existing mapping
+mechanisms and so provides only an abstraction layer and no new
+functionality.
+On 64-bit processors, io_mapping_create_wc calls ioremap_wc for the whole
+range, creating a permanent kernel-visible mapping to the resource. The
+map_atomic and map functions add the requested offset to the base of the
+virtual address returned by ioremap_wc.
+On 32-bit processors with HIGHMEM defined, io_mapping_map_atomic_wc uses
+kmap_atomic_pfn to map the specified page in an atomic fashion;
+kmap_atomic_pfn isn't really supposed to be used with device pages, but it
+provides an efficient mapping for this usage.
+On 32-bit processors without HIGHMEM defined, io_mapping_map_atomic_wc and
+io_mapping_map_wc both use ioremap_wc, a terribly inefficient function which
+performs an IPI to inform all processors about the new mapping. This results
+in a significant performance penalty.

+Driver for USB radios for the Silicon Labs Si470x FM Radio Receivers
+Copyright (c) 2008 Tobias Lorenz <tobias.lorenz@gmx.net>
+Information from Silicon Labs
+=============================
+Silicon Laboratories is the manufacturer of the radio ICs, that nowadays are the
+most often used radio receivers in cell phones. Usually they are connected with
+I2C. But SiLabs also provides a reference design, which integrates this IC,
+together with a small microcontroller C8051F321, to form a USB radio.
+Part of this reference design is also a radio application in binary and source
+code. The software also contains an automatic firmware upgrade to the most
+current version. Information on these can be downloaded here:
+http://www.silabs.com/usbradio
+Supported ICs
+=============
+The following ICs have a very similar register set, so that they are or will be
+supported somewhen by the driver:
+- Si4700: FM radio receiver
+- Si4701: FM radio receiver, RDS Support
+- Si4702: FM radio receiver
+- Si4703: FM radio receiver, RDS Support
+- Si4704: FM radio receiver, no external antenna required
+- Si4705: FM radio receiver, no external antenna required, RDS support, Dig I/O
+- Si4706: Enhanced FM RDS/TMC radio receiver, no external antenna required, RDS
+          Support
+- Si4707: Dedicated weather band radio receiver with SAME decoder, RDS Support
+- Si4708: Smallest FM receivers
+- Si4709: Smallest FM receivers, RDS Support
+More information on these can be downloaded here:
+http://www.silabs.com/products/mcu/Pages/USBFMRadioRD.aspx
+Supported USB devices
+=====================
+Currently the following USB radios (vendor:product) with the Silicon Labs si470x
+chips are known to work:
+- 10c4:818a: Silicon Labs USB FM Radio Reference Design
+- 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music) (RDX-155-EF)
+- 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
+Software
+========
+Testing is usually done with most application under Debian/testing:
+- fmtools - Utility for managing FM tuner cards
+- gnomeradio - FM-radio tuner for the GNOME desktop
+- gradio - GTK FM radio tuner
+- kradio - Comfortable Radio Application for KDE
+- radio - ncurses-based radio application
+There is also a library libv4l, which can be used. It's going to have a function
+for frequency seeking, either by using hardware functionality as in radio-si470x
+or by implementing a function as we currently have in every of the mentioned
+programs. Somewhen the radio programs should make use of libv4l.
+For processing RDS information, there is a project ongoing at:
+http://rdsd.berlios.de/
+There is currently no project for making TMC sentences human readable.
+Audio Listing
+=============
+USB Audio is provided by the ALSA snd_usb_audio module. It is recommended to
+also select SND_USB_AUDIO, as this is required to get sound from the radio. For
+listing you have to redirect the sound, for example using one of the following
+commands.
+If you just want to test audio (very poor quality):
+cat /dev/dsp1 > /dev/dsp
+If you use OSS try:
+sox -2 --endian little -r 96000 -t oss /dev/dsp1 -t oss /dev/dsp
+If you use arts try:
+arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
+Module Parameters
+=================
+After loading the module, you still have access to some of them in the sysfs
+mount under /sys/module/radio_si470x/parameters. The contents of read-only files
+(0444) are not updated, even if space, band and de are changed using private
+video controls. The others are runtime changeable.
+Errors
+======
+Increase tune_timeout, if you often get -EIO errors.
+When timed out or band limit is reached, hw_freq_seek returns -EAGAIN.
+If you get any errors from snd_usb_audio, please report them to the ALSA people.
+Open Issues
+===========
+V4L minor device allocation and parameter setting is not perfect. A solution is
+currently under discussion.
+There is an USB interface for downloading/uploading new firmware images. Support
+for it can be implemented using the request_firmware interface.
+There is a RDS interrupt mode. The driver is already using the same interface
+for polling RDS information, but is currently not using the interrupt mode.
+There is a LED interface, which can be used to override the LED control
+programmed in the firmware. This can be made available using the LED support
+functions in the kernel.
+Other useful information and links

+Kernel driver for omap HDQ/1-wire module.
+========================================
+Supported chips:
+================
+        HDQ/1-wire controller on the TI OMAP 2430/3430 platforms.
+A useful link about HDQ basics:
+===============================
+http://focus.ti.com/lit/an/slua408/slua408.pdf
+Description:
+============
+The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware
+protocol of the master functions of the Benchmark HDQ and the Dallas
+Semiconductor 1-Wire protocols. These protocols use a single wire for
+communication between the master (HDQ/1-Wire controller) and the slave
+(HDQ/1-Wire external compliant device).
+A typical application of the HDQ/1-Wire module is the communication with battery
+monitor (gas gauge) integrated circuits.
+The controller supports operation in both HDQ and 1-wire mode. The essential
+difference between the HDQ and 1-wire mode is how the slave device responds to
+initialization pulse.In HDQ mode, the firmware does not require the host to
+create an initialization pulse to the slave.However, the slave can be reset by
+using an initialization pulse (also referred to as a break pulse).The slave
+does not respond with a presence pulse as it does in the 1-Wire protocol.
+Remarks:
+========
+The driver (drivers/w1/masters/omap_hdq.c) supports the HDQ mode of the
+controller. In this mode, as we can not read the ID which obeys the W1
+spec(family:id:crc), a module parameter can be passed to the driver which will
+be used to calculate the CRC and pass back an appropriate slave ID to the W1
+core.
+By default the master driver and the BQ slave i/f
+driver(drivers/w1/slaves/w1_bq27000.c) sets the ID to 1.
+Please note to load both the modules with a different ID if required, but note
+that the ID used should be same for both master and slave driver loading.
+e.g:
+insmod omap_hdq.ko W1_ID=2
+inamod w1_bq27000.ko F_ID=2
