@ -54,13 +54,16 @@ If you really want i2c accesses for these Super I/O chips,
use the w83781d driver. However this is not the preferred method
now that this ISA driver has been developed.
Technically, the w83627thf does not support a VID reading. However, it's
possible or even likely that your mainboard maker has routed these signals
to a specific set of general purpose IO pins (the Asus P4C800-E is one such
board). The w83627thf driver now interprets these as VID. If the VID on
your board doesn't work, first see doc/vid in the lm_sensors package. If
that still doesn't help, email us at lm-sensors@lm-sensors.org.
The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the
same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a
VID reading. However the two chips have the identical 128 pin package. So,
it is possible or even likely for a w83627thf to have the VID signals routed
to these pins despite their not being labeled for that purpose. Therefore,
the w83627thf driver interprets these as VID. If the VID on your board
doesn't work, first see doc/vid in the lm_sensors package[1]. If that still
doesn't help, you may just ignore the bogus VID reading with no harm done.
For further information on this driver see the w83781d driver
documentation.

This is a guide on how to convert I2C chip drivers from Linux 2.4 to
Linux 2.6. I have been using existing drivers (lm75, lm78) as examples.
Then I converted a driver myself (lm83) and updated this document.
Note that this guide is strongly oriented towards hardware monitoring
drivers. Many points are still valid for other type of drivers, but
others may be irrelevant.
There are two sets of points below. The first set concerns technical
changes. The second set concerns coding policy. Both are mandatory.

In i2c-only drivers, drop the i2c_is_isa_adapter check, it's
useless. Same for isa-only drivers, as the test would always be
true. Only hybrid drivers (which are quite rare) still need it.
The errorN labels are reduced to the number needed. If that number
is 2 (i2c-only drivers), it is advised that the labels are named
exit and exit_free. For i2c+isa drivers, labels should be named
ERROR0, ERROR1 and ERROR2. Don't forget to properly set err before
The labels used for error paths are reduced to the number needed.
It is advised that the labels are given descriptive names such as
exit and exit_free. Don't forget to properly set err before
jumping to error labels. By the way, labels should be left-aligned.
Use kzalloc instead of kmalloc.
Use i2c_set_clientdata to set the client data (as opposed to
a direct access to client->data).
Use strlcpy instead of strcpy to copy the client name.
Use strlcpy instead of strcpy or snprintf to copy the client name.
Replace the sysctl directory registration by calls to
device_create_file. Move the driver initialization before any
sysfs file creation.
Register the client with the hwmon class (using hwmon_device_register)
if applicable.
Drop client->id.
Drop any 24RF08 corruption prevention you find, as this is now done
at the i2c-core level, and doing it twice voids it.
Don't add I2C_CLIENT_ALLOW_USE to client->flags, it's the default now.
* [Init] Limits must not be set by the driver (can be done later in
user-space). Chip should not be reset default (although a module
parameter may be used to force is), and initialization should be
parameter may be used to force it), and initialization should be
limited to the strictly necessary steps.
* [Detach] Get rid of data, remove the call to
i2c_deregister_entry. Do not log an error message if
i2c_detach_client fails, as i2c-core will now do it for you.
* [Detach] Remove the call to i2c_deregister_entry. Do not log an
error message if i2c_detach_client fails, as i2c-core will now do
it for you.
Unregister from the hwmon class if applicable.
* [Update] Don't access client->data directly, use
i2c_get_clientdata(client) instead.
* [Update] The function prototype changed, it is now
passed a device structure, which you have to convert to a client
using to_i2c_client(dev). The update function should return a
pointer to the client data.
Don't access client->data directly, use i2c_get_clientdata(client)
instead.
Use time_after() instead of direct jiffies comparison.

there is a MODULE_LICENSE() line, at the bottom of the file
(after MODULE_AUTHOR() and MODULE_DESCRIPTION(), in this order).

string. i2c_driver itself has no name member anymore.
Coding policy:
* [Copyright] Use (C), not (c), for copyright.

can. Calls to printk/pr_debug for debugging purposes are replaced
by calls to dev_dbg. Here is an example on how to call it (taken
from lm75_detect):

dev_dbg where possible, else to pr_debug. Here is an example of how
to call it (taken from lm75_detect):

Replace other printk calls with the dev_info, dev_err or dev_warn
function, as appropriate.
* [Constants] Constants defines (registers, conversions, initial
values) should be aligned. This greatly improves readability.
Same goes for variables declarations. Alignments are achieved by the
means of tabs, not spaces. Remember that tabs are set to 8 in the
