2013-01-25hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck
SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds.

2012-10-10hwmon: Add missing inclusions of <linux/jiffies.h>Jean Delvare
Many hwmon drivers use jiffies but omit the inclusion of the header file. Fix that, and also fix one driver which was including the header file but didn't need it.

2012-07-21hwmon: (adt7475) Convert to use devm_ functionsGuenter Roeck
Convert to use devm_ functions to reduce code size and simplify the code. Cc: Jean Delvare <khali@linux-fr.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
2012-03-18hwmon: 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.

2010-10-28hwmon: I2C addresses are constantJean Delvare
We can mark normal_i2c const. Almost all drivers do that already, so fix the 3 remaining ones before they are used as (bad) examples for new drivers.

2009-12-14i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare
These macros simply declare an enum, so drivers might as well declare it themselves. This puts an end to the arbitrary limit of 8 chip types per i2c driver. 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>
2009-12-09hwmon: (adt7475) Add VID support for the ADT7476Jean Delvare
The ADT7476 has 5 dedicated pins for VID input, and the +12V input can optionally be used as a 6th VID pin. Add support for VID input.

2009-12-09hwmon: (adt7475) Add support for the ADT7476Jean Delvare
Add support for the Analog Devices ADT7476 chip. This chip is largely compatible with the ADT7473 and ADT7475, with additional features. In particular, it has 5 voltage inputs instead of 2, and VID input pins.

2009-12-09hwmon: (adt7475) Voltage attenuators can be bypassedJean Delvare
It is possible to bypass the voltage attenuators on the +2.5V, Vccp, +5V and +12V voltage monitoring inputs. This is useful to connect other voltage channels than the ones the monitoring chip was originally designed for. When this feature is enabled, we must not include the scaling factors in our computations.

2009-12-09hwmon: (adt7475) Handle alternative pin functionsJean Delvare
The TACH4 pin can be used for other functions, so fan4 may not always be available. Likewise, the PWM2 pin can be used for ALERT output, in which case pwm2 is not available For the ADT7490, the +2.5 Vin pin may also be used for other functions, in which case in0 is not available.

2009-12-09hwmon: (adt7475) Move sysfs files removal to a separate functionJean Delvare
Move sysfs files removal to a separate function. The code is common to the device probing error path and the standard device removal path. As it will grow with future driver development, this avoids code duplication.

2009-12-09hwmon: (adt7475) Add support for the ADT7473Jean Delvare
Add support for the ADT7473 to the adt7475 driver, and mark the adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost the same chip and essentially compatible, so there's no point in having separate drivers for them.

2009-11-16hwmon: (adt7475) Fix sysfs file namesJean Delvare

2009-11-16hwmon: (adt7475) Cache limits for 60 secondsJean Delvare
The comment says that limits are cached for 60 seconds but the code actually caches them for only 2 seconds. Align the code on the comment, as 60 seconds makes more sense.

2009-11-16hwmon: (adt7475) Fix temperature fault flagsJean Delvare
The logic of temperature fault flags is wrong, it shows faults when there are none and vice versa. Fix it. I can't believe this has been broken since the driver was added, 8 months ago, basically breaking temp1 and temp3, and nobody ever complained.
