+The following specification describes the SMSC LPC47B397-NC sensor chip
+(for which there is no public datasheet available).  This document was
+provided by Craig Kelly (In-Store Broadcast Network) and edited/corrected
+by Mark M. Hoffman <mhoffman@lightlink.com>.

+
+Methods for detecting the HP SIO and reading the thermal data on a dc7100.
+
+The thermal information on the dc7100 is contained in the SIO Hardware Monitor
+(HWM).  The information is accessed through an index/data pair.  The index/data
+pair is located at the HWM Base Address + 0 and the HWM Base Address + 1.  The
+HWM Base address can be obtained from Logical Device 8, registers 0x60 (MSB)
+and 0x61 (LSB).  Currently we are using 0x480 for the HWM Base Address and
+0x480 and 0x481 for the index/data pair.
+
+Reading temperature information.
+The temperature information is located in the following registers:
+Temp1		0x25	(Currently, this reflects the CPU temp on all systems).
+Temp2		0x26
+Temp3		0x27
+Temp4		0x80
+
+Programming Example
+The following is an example of how to read the HWM temperature registers:
+MOV	DX,480H
+MOV	AX,25H
+OUT	DX,AL
+MOV	DX,481H
+IN	AL,DX
+
+AL contains the data in hex, the temperature in Celsius is the decimal
+equivalent.
+
+Ex: If AL contains 0x2A, the temperature is 42 degrees C.
+
+Reading tach information.
+The fan speed information is located in the following registers:
+		LSB	MSB
+Tach1		0x28	0x29	(Currently, this reflects the CPU
+				fan speed on all systems).
+Tach2		0x2A	0x2B
+Tach3		0x2C	0x2D
+Tach4		0x2E	0x2F
+
+Important!!!
+Reading the tach LSB locks the tach MSB.
+The LSB Must be read first.
+
+How to convert the tach reading to RPM.
+The tach reading (TCount) is given by:  (Tach MSB * 256) + (Tach LSB)
+The SIO counts the number of 90kHz (11.111us) pulses per revolution.
+RPM = 60/(TCount * 11.111us)
+
+Example:
+Reg 0x28 = 0x9B
+Reg 0x29 = 0x08
+
+TCount = 0x89B = 2203
+
+RPM = 60 / (2203 * 11.11111 E-6) = 2451 RPM
+
+Obtaining the SIO version.
+
+CONFIGURATION SEQUENCE
+To program the configuration registers, the following sequence must be followed:
+1. Enter Configuration Mode
+2. Configure the Configuration Registers
+3. Exit Configuration Mode.
+
+Enter Configuration Mode
+To place the chip into the Configuration State The config key (0x55) is written
+to the CONFIG PORT (0x2E). 
+
+Configuration Mode
+In configuration mode, the INDEX PORT is located at the CONFIG PORT address and
+the DATA PORT is at INDEX PORT address + 1.
+
+The desired configuration registers are accessed in two steps: 
+a.	Write the index of the Logical Device Number Configuration Register
+	(i.e., 0x07) to the INDEX PORT and then write the number of the
+	desired logical device to the DATA PORT.
+
+b.	Write the address of the desired configuration register within the
+	logical device to the INDEX PORT and then write or read the config-
+	uration register through the DATA PORT.  
+
+Note: If accessing the Global Configuration Registers, step (a) is not required.
+
+Exit Configuration Mode
+To exit the Configuration State the write 0xAA to the CONFIG PORT (0x2E).
+The chip returns to the RUN State.  (This is important).
+
+Programming Example
+The following is an example of how to read the SIO Device ID located at 0x20
+
+; ENTER CONFIGURATION MODE   
+MOV	DX,02EH
+MOV	AX,055H
+OUT	DX,AL
+; GLOBAL CONFIGURATION  REGISTER 
+MOV	DX,02EH
+MOV	AL,20H
+OUT	DX,AL 
+; READ THE DATA
+MOV	DX,02FH
+IN	AL,DX
+; EXIT CONFIGURATION MODE     
+MOV	DX,02EH
+MOV	AX,0AAH
+OUT	DX,AL
+
+The registers of interest for identifying the SIO on the dc7100 are Device ID
+(0x20) and Device Rev  (0x21).
+
+The Device ID will read 0X6F
+The Device Rev currently reads 0x01
+
+Obtaining the HWM Base Address.
+The following is an example of how to read the HWM Base Address located in
+Logical Device 8.
+
+; ENTER CONFIGURATION MODE   
+MOV	DX,02EH
+MOV	AX,055H
+OUT	DX,AL
+; CONFIGURE REGISTER CRE0,   
+; LOGICAL DEVICE 8           
+MOV	DX,02EH
+MOV	AL,07H
+OUT	DX,AL ;Point to LD# Config Reg
+MOV	DX,02FH
+MOV	AL, 08H
+OUT	DX,AL;Point to Logical Device 8
+;
+MOV	DX,02EH 
+MOV	AL,60H
+OUT	DX,AL	; Point to HWM Base Addr MSB
+MOV	DX,02FH
+IN	AL,DX	; Get MSB of HWM Base Addr
+; EXIT CONFIGURATION MODE     
+MOV	DX,02EH
+MOV	AX,0AAH
+OUT	DX,AL

-I2C Conversion Guide for I2C-old to the current I2C API
-July 2002
-For Linux Kernel v2.5.x
-Frank Davis <fdavis@si.rr.com>
--------------------------------------------------------
-
-There exists several kernel drivers that are using an old version of the I2C
-API. These drivers need to be converted to the current (kernel 2.5.x) version.
-The following document provides a guideline to make the appropriate changes to
-the affected drivers. There maybe slight modifications to this guide that are 
-specific to the driver you are working on. If you see {driver_name}, replace 
-that with the respective name of the driver, such as saa7110.c , {driver_name} 
-= saa7110.
-
--------------------------------------------------------
-
-Step 1: Include the right header file
- 
-Perform the following change within the driver
- 
-#include <linux/i2c-old.h> --> #include <linux/i2c.h>
-
-Step 2: Add and set the i2c modes
-
-Add the following code near the top of the driver
-
-static unsigned short normal_i2c[] = {34>>1, I2C_CLIENT_END };
-static unsigned short normal_i2c_range[] = { I2C_CLIENT_END };
-static unsigned short probe[2] = { I2C_CLIENT_END , I2C_CLIENT_END };
-static unsigned short probe_range[2] = { I2C_CLIENT_END , I2C_CLIENT_END };	
-static unsigned short ignore[2] = { I2C_CLIENT_END , I2C_CLIENT_END };
-static unsigned short ignore_range[2] = { I2C_CLIENT_END, I2C_CLIENT_END };
-static unsigned short force[2] = { I2C_CLIENT_END , I2C_CLIENT_END };
-
-static struct i2c_client_address_data addr_data  = {
-	normal_i2c , normal_i2c_range,
-	probe , probe_range,
-	ignore , ignore_range,
-	force
-};
-
-static struct i2c_client client_template;
-
-Step 3: Modify the driver info struct
-
-Within the struct for the driver , such as struct {driver_name}  ,  make the 
-following change ,
-struct i2c_bus *bus --> struct i2c_client *client
-
-Make changes where this change affects references within the file.
-
-Add a semaphore to the driver struct (as above)
-
-struct semaphore lock 
-
-Step 5: Remove specific read and write functions
-
-Remove the driver specific write and read functions, usually in the form:
-{driver_name}_write , {driver_name}_read , {driver_name}_write_block , etc.
-
-Step 6: Update the write and read functions for the current I2C API
-
-Replace all references of {driver_name}_write with i2c_smbus_write_byte_data
-Replace all references of {driver_name}_read with i2c_smbus_read_byte_data or
-i2c_smbus_read_byte , depending on args passed in.
-
-** Ensure that these functions pass in the i2c_client *client , NOT the
-decoder/encoder that was passed in the driver specific write and read
-functions. 
- 
-Step 7: Modify the driver's attach function
-
-Change the driver attach function prototype :
-{driver_name}_attach(struct i2c_device *device) --> {driver_name}_attach(struct 
-i2c_adapter *adap, int addr , unsigned short flags, int kind)
-
-Create a i2c_client client...
-Add the following (where "decoder" is a reference to a struct for the driver
-info:
-
-struct i2c_client *client;
-client = kmalloc(sizeof(*client), GFP_KERNEL);
-if(client == NULL)
-	return -ENOMEM;
-client_template.adapter = adap;
-client_template.addr  = addr;
-memcpy(client, &client_template, sizeof(*client));
-strcpy(client->name , "{driver_name}");
-decoder->client = client;
-client->data = decoder;
-decoder->addr = addr;
-
-Towards the end of the function, add:
-
-init_MUTEX(&decoder->lock);
-i2c_attach_client(client);
-
-
-Step 8: Modify the driver's detach function
-
-Change the driver detach function prototype :
-{driver_name}_detach(struct i2c_device *device) --> {driver_name}_detach(struct 
-i2c_client *client)
-
-In the beginning of the detach function, add:
-i2c_detach_client(client);
-
-Towards the end of the detach function, add:
-kfree(client->data);
-kfree(client);
-
-Step 9: Modify the driver's command function
-
-Change the driver command function prototype :
-
-Step 10: Add the probe function after the driver's attach function.
-
-Add the following code:
-
-static int {driver_name}_probe(struct i2c_adapter *adap)
-{
-	return i2c_probe(adap, &addr_data, {driver_name}_attach);
-
-}
-
-Step 11: Modify the driver's i2c_driver
-
-Find the i2c_driver , such as
-static struct i2c_driver i2c_driver_saa7110
-It is usually located towards the end of the driver 
-Replace the values from I2C_DRIVERID_{something} to {driver_name}_attach, and 
-add the following
-I2C_DRIVERID_{driver_name} , // verify by looking in include/linux/i2c-id.h 
-I2C_DF_NOTIFY,
-{driver_name}_probe, 
-....
-
-Step 12: Adding the i2c_client 
-
-Add the i2c_client to the driver. Add the following code:
-
-static struct i2c_client client_template = {
-	"{driver_name}_client",
-	-1,
-	0,
-	0,
-	NULL,
-	{i2c_driver reference}
-};
-
-Step 13: Registering and Unregistering
-
-Replace i2c_register_driver with i2c_add_driver
-Replace i2c_unregister_driver with i2c_del_driver
-
--------------------------------------------------------
-
-Example:
-
-The following patch provides the i2c coversion patch for the saa7110 driver
-based on the above guide (for clarity).

 DESCRIPTION:
 
-This module is a very simple fake I2C/SMBus driver.  It implements three
-types of SMBus commands: write quick, (r/w) byte data, and (r/w) word data.
+This module is a very simple fake I2C/SMBus driver.  It implements four
+types of SMBus commands: write quick, (r/w) byte, (r/w) byte data, and
+(r/w) word data.
 
 No hardware is needed nor associated with this module.  It will accept write
 quick commands to all addresses; it will respond to the other commands (also
 to all addresses) by reading from or writing to an array in memory.  It will
 also spam the kernel logs for every command it handles.
 
+A pointer register with auto-increment is implemented for all byte
+operations.  This allows for continuous byte reads like those supported by
+EEPROMs, among others.
+
 The typical use-case is like this:
 	1. load this module
 	2. use i2cset (from lm_sensors project) to pre-load some data

Documentation/w1/w1.generic

+Any w1 device must be connected to w1 bus master device - for example
+ds9490 usb device or w1-over-GPIO or RS232 converter.
+Driver for w1 bus master must provide several functions(you can find
+them in struct w1_bus_master definition in w1.h) which then will be
+called by w1 core to send various commands over w1 bus(by default it is
+reset and search commands). When some device is found on the bus, w1 core
+checks if driver for it's family is loaded.
+If driver is loaded w1 core creates new w1_slave object and registers it
+in the system(creates some generic sysfs files(struct w1_family_ops in
+w1_family.h), notifies any registered listener and so on...).
+It is device driver's business to provide any communication method
+upstream.
+For example w1_therm driver(ds18?20 thermal sensor family driver)
+provides temperature reading function which is bound to ->rbin() method
+of the above w1_family_ops structure.
+w1_smem - driver for simple 64bit memory cell provides ID reading
+method.
+
+You can call above methods by reading appropriate sysfs files.
