* hwmon: (lm78/w83781d) Probe fewer I2C addressesJean Delvare2008-02-07
| | | | | | | | | We've never seen any device supported by the lm78 or w83781d driver at addresses 0x20-0x27, so let's stop probing these addresses. Extra probes cost time, and have potential for confusing or misdetecting other I2C devices. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

* hwmon: End of I/O region off-by-oneJean Delvare2007-09-09
| | | | | | | | | Fix an off-by-one error in the I/O region declaration of two hardware monitoring drivers (lm78 and w83781d.) We were requesting one extra port at the end of the region. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
* hwmon: fix lm78 detection regressionHans de Goede2007-07-30
| | | | | | | | | | | | | | | Here is a small but important bugfix to the lm78 driver. I found out about this problem because a Fedora user filed a bug that the lm78 driver no longer worked on his system: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249428 The problem is that sometime ago the isa lm78 detection was made more stringent and this new code now checks the chip-id, but does not accept a chip-id of 20h, however a chip-id of 20h is valid, and is excepted in the main probe function of the driver, see line 551. This fixed also makes the isa detection code accept the chip-id of 0x20 fixing this issue. Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
* hwmon/lm78: Use dynamic sysfs callbacksJean Delvare2007-05-08
| | | | | | | This lets us get rid of macro-generated functions and shrinks the driver size significantly (about 10%). Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon/lm78: Be less i2c_client-centricJean Delvare2007-05-08
| | | | | | | | Use the driver data structure as the main device reference, instead of the i2c client. It makes the driver a bit smaller, and makes more sense as this is an hybrid driver, supporting both I2C and ISA devices. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon/lm78: No longer use i2c-isaJean Delvare2007-05-08
| | | | | | | Reimplement the ISA device support as a platform driver, so that we no longer rely on i2c-isa. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: Let w83781d and lm78 load againJean Delvare2006-10-18
| | | | | | | | | | | | | Let the w83781d and lm78 hardware monitoring drivers load even when no chip was detected at the ISA address. There can still be supported chips connected to an I2C bus or SMBus. This fixes bug #7293. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] I2C: hwmon: Rename register parametersDarren Jenkins2006-03-23
| | | | | | | | | | | | "register" is a reserved keyword so using it as a parameter name can confuse some compilers, most notably ICC. The patch below just renames all occurences to reg which fits the actual function declarations.

* [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman2006-01-06
| | | | | | | | | | 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.)

* [PATCH] i2c: Drop i2c_driver.{owner,name}, 3 of 11Laurent Riffard2006-01-06
| | | | | | | | | | | We should use the i2c_driver.driver's .name and .owner fields instead of the i2c_driver's ones. This patch updates the hwmon drivers.

* [PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare2006-01-06
| | | | | | | | | | | 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>
* [PATCH] hwmon: Fix lm78 VID conversionJean Delvare2005-11-24
| | | | | | | | | | | | Fix the lm78 VID reading, which I accidentally broke while making this driver use the common vid_from_reg function rather than reimplementing its own in 2.6.14-rc1.

* [PATCH] hwmon: hwmon vs i2c, second round (06/11)Jean Delvare2005-09-05
| | | | | | | | | | | 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.

* [PATCH] I2C: refactor message in i2c_detach_clientJean Delvare2005-09-05
| | | | | | | | | | | | 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.

* [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)Jean Delvare2005-09-05
| | | | | | | | | | | 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>
* [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)Jean Delvare2005-09-05
| | | | | | | | | | | | | | | Call the ISA chip drivers detection function directly instead of relying on i2c_detect. The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)Jean Delvare2005-09-05
| | | | | | | | | | | | | | Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360, sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to explicitely register with i2c-isa. For hybrid drivers (it87, lm78, w83781d), we now have two separate instances of i2c_driver, one for the I2C interface of the chip, and one for ISA interface. In the long run, the one for ISA will be replaced with a different driver type. At this point, all drivers are working again, except for missing dependencies in Kconfig.

* [PATCH] hwmon: kill client name lm78-jJean Delvare2005-09-05
| | | | | | | | | | | | | | | Drop the separate client name for the LM78-J chip. This is really only a later revision of the LM78, with almost no difference and no difference the driver handles in any case. This was the only client name that had a dash in it, and special care had to be taken in libsensors because of it. As we plan to write a new library soon, I'd like to get rid of this exception before we do. As a nice side effect, it saves 876 bytes in lm78.ko.

* [PATCH] I2C: Move hwmon drivers (2/3)Jean Delvare2005-07-11
