2009-03-30Move the pcf8591 driver to hwmonJean Delvare
Directory drivers/i2c/chips is going away, so drivers there must find new homes. For the pcf8591 driver, the best choice seems to be the hwmon subsystem. While the Philips PCF8591 device isn't a typical hardware monitoring chip, its DAC interface is compatible with the hwmon one, so it fits somewhat. If a better subsystem is ever created for ADC/DAC chips, the driver could be moved there. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Aurelien Jarno <aurelien@aurel32.net>
2008-07-16i2c: Convert the pcf8591 driver to a new-style i2c driverJean Delvare
The new-style pcf8591 driver implements the optional detect() callback to cover the use cases of the legacy driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-07-14i2c: Clean up old chip driversJean Delvare
Clean up old i2c chip drivers: * Name the i2c_client "client" instead of "new_client". * Drop useless initializations to 0. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-02-07hwmon: Discard useless I2C driver IDsJean Delvare
Many I2C hwmon drivers define a driver ID but no other code references these, meaning that they are useless. Discard them, along with a few IDs which are defined but never used at all. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

2006-09-26i2c: __must_check fixes (chip drivers)Jean Delvare
i2c: __must_check fixes (chip drivers) Check for error on sysfs file creation. Delete sysfs files on device removal. The approach taken for the most complex case (pcf8591) is similar to what Mark M. Hoffman proposed for hardware monitoring chip drivers.

2006-03-23[PATCH] i2c: Semaphore to mutex conversions, part 2Ingo Molnar
semaphore to mutex conversion. the conversion was generated via scripts, and the result was validated automatically via a script as well. build tested. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-05[PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman
Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers. This patch catches all of the drivers that I found in the current tree (if a driver sets the .owner by hand, it's not a problem, just not needed.)

2006-01-05[PATCH] i2c: Drop i2c_driver.{owner,name}, 2 of 11Laurent Riffard
We should use the i2c_driver.driver's .name and .owner fields instead of the i2c_driver's ones. This patch updates the miscellaneaous i2c chip drivers.

2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare
Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we can simply make it the default and drop the flag. If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter. This approach is also more robust as it prevents accidental NULL pointer dereferences. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (06/11)Jean Delvare
The only thing left in i2c-sensor.h are module parameter definition macros. It's only an extension of what i2c.h offers, and this extension is not sensors-specific. As a matter of fact, a few non-sensors drivers use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h altogether.

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (04/11)Jean Delvare
i2c_probe and i2c_detect now do the exact same thing and operate on the same data structure, so we can have everyone call i2c_probe. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-05[PATCH] I2C: refactor message in i2c_detach_clientJean Delvare
We could refactor the error message 34 different i2c drivers print if i2c_detach_client() fails in this function itself. Saves quite a few lines of code. Documentation is updated to reflect that change. Note that this patch should be applied after Rudolf Marek's w83792d patches.

2005-09-05[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)Jean Delvare
Kill normal_isa in header files, documentation and all chip drivers, as it is no more used. normal_i2c could be renamed to normal, but I decided not to do so at the moment, so as to limit the number of changes. This might be done later as part of the i2c_probe/i2c_detect merge. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
