2014-05-21hwmon: (lm80) Rearrange code to avoid forward declarationsGuenter Roeck
Avoid need for forward declarations by rearranging code. No functional change. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (lm80) Convert fan display function macros into functionsGuenter Roeck
Convert fan display function macros into functions to reduce code size and improve code readability. Code size reduction is about 200 bytes on x86_64. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (lm80) Convert voltage display function macros into functionsGuenter Roeck
Convert voltage display function macros into functions to reduce code size and improve code readability. Code size reduction is about 600 bytes on x86_64. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (lm80) Convert temperature display function macros into functionsGuenter Roeck
Convert temperature display function macros into functions to reduce code size and improve code readability. Code size reduction is about 2k on x86_64. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (lm80) Normalize all temperature values to 16 bitGuenter Roeck
Normalize all stored temperature values to 16 bit to simplify temperature calculations. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (lm80) Simplify TEMP_FROM_REGGuenter Roeck
TEMP_FROM_REG gets 12 bits of temperature data in the upper 12 bit of a signed 16 bit parameter, with the integer part (including sign) in the upper 8 bit and the remainder in bit 4..7. The lower 4 bit of the 16 bit data is always 0. We can use that information to convert the temperature directly into display data (1/1000th of degree C). Note that the stored temperature data is not shifted right as the comment claimed, so remove that misleading comment. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-04-04hwmon: (lm80) Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck

2012-03-19hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin
This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

2012-03-19hwmon: (lm80) reset device if error occurredFrans Meulenbroeks
If an error occurs while updating (e.g. because the chip was disconnected) the device needs to be reinitialized in order to get back to 11 bit temperature and set the fan divider. Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2012-03-19hwmon: (lm80) fix checkpatch warningsFrans Meulenbroeks

2012-03-19hwmon: (lm80) add error handlingFrans Meulenbroeks
The LM80 driver currently does not return errors after I2C access failures. Add it. Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2012-01-05hwmon: (lm80) fix checkpatch messagesFrans Meulenbroeks
Fixed all checkpatch messages except simple_strto* -> kstr* This will be addressed in a separate patch Also left one line-too-long message as it was only a little bit too long and would become less readable compile-tested: no warnings or errors Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2009-12-14i2c: Drop I2C_CLIENT_INSMOD_1Jean Delvare
This macro simply declares an enum, so drivers might as well declare it themselves. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare
Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Drop the kind parameter from detect callbacksJean Delvare
The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2008-07-16hwmon: (lm80) Convert to a new-style i2c driverJean Delvare
The new-style lm80 driver implements the optional detect() callback to cover the use cases of the legacy driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-02-19hwmon: normal_i2c arrays should be constMark M. Hoffman
Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-08hwmon: (lm80) Add individual alarm filesJean Delvare
The new libsensors needs these individual alarm files. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-08hwmon: (lm80) De-macro the sysfs callbacksJean Delvare
Use standard dynamic sysfs callbacks instead of macro-generated functions. This makes the code more readable, and the binary smaller (by about 34%). As a side note, another benefit of this type of cleanup is that they shrink the build time. For example, this cleanup saves about 29% of the lm80 driver build time.

2008-02-08hwmon: (lm80) Various cleanupsJean Delvare

2008-02-08hwmon: 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>

2006-03-23[PATCH] hwmon: Semaphore to mutex conversionsIngo Molnar
convert drivers/hwmon/*.c semaphore use to mutexes. the conversion was generated via scripts, and the result was validated automatically via a script as well. all affected hwmon drivers were build-tested.

2006-01-06[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.) Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Cc: Jean Delvare <khali@linux-fr.org>
2006-01-06[PATCH] i2c: Drop i2c_driver.{owner,name}, 3 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 hwmon drivers. Signed-off-by: Laurent Riffard <laurent.riffard@free.fr> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-06[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. Signed-off-by: Jean Delvare <khali@linux-fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
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>

2005-07-11[PATCH] I2C: Move hwmon drivers (2/3)Jean Delvare
Part 2: Move the driver files themselves. Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace. From: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
