[PATCH] I2C: Discard old driver porting documentation
The Documentation/i2c/i2c-old-porting file is outdated. There are no
more drivers left to be ported from that old i2c model (from the times
of Linux 2.2). Let's simply delete that file.

-I2C Conversion Guide for I2C-old to the current I2C API
-July 2002
-For Linux Kernel v2.5.x
-Frank Davis <fdavis@xxxxxxxxx>
--------------------------------------------------------
-
-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).
