2009-01-07adt74{62, 70, 73}: Use DIV_ROUND_CLOSEST for rounded divisionDarrick J. Wong1-6/+4
Modify some hwmon drivers to use DIV_ROUND_CLOSEST instead of bloating source with (naughty) macros. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Cc: Jean Delvare <khali@linux-fr.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-13adt7473: check inputs from sysfs writesDarrick J. Wong1-15/+74
Implement correct range checking for adt7470 to prevent userland from writing impossible values into the chip, and cap out-of-range values per standard hwmon conventions. Implement correct rounding of input values per standard hwmon conventions. Signed-off-by: Darrick J.

2008-10-26hwmon: (adt7473) Fix voltage conversion routinesJean Delvare1-20/+9
Fix voltage conversion routines. Based on an earlier patch from Paulius Zaleckas. According to the datasheet voltage is scaled with resistors and value 192 is nominal voltage. 0 is 0V.

2008-08-01hwmon: (adt7473) Remove unused definesJean Delvare1-13/+0
All the *_MAX_ADDR defines are never used, so remove them. The number of registers of each type is already expressed by the *_COUNT defines. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-07-16hwmon: (adt7473) Convert to a new-style i2c driverJean Delvare1-54/+48
The new-style adt7473 driver implements the optional detect() callback to cover the use cases of the legacy driver. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Darrick J. Wong <djwong@us.ibm.com>
2008-06-19hwmon: (adt7473) Initialize max_duty_at_overheat before useJean Delvare1-0/+3
data->max_duty_at_overheat is not updated in adt7473_update_device, so it might be used before it is initialized (if the user reads from sysfs file max_duty_at_crit before writing to it.)
