hwmon: (max1668) Fix writing the minimum temperature

2014-02-18T23:53:49+00:00

When trying to set the minimum temperature, the driver was erroneously
writing the maximum temperature into the chip.

hwmon: (ntc_thermistor) Avoid math overflow

2014-02-14T03:43:52+00:00

The ntc thermistor code was doing math whose temporary result might
have overflowed 32-bits.  We need some casts in there to make it safe.

In one example I found:
- pullup_uV: 1800000
- result of iio_read_channel_raw: 3226
- 1800000 * 3226 => 0x15a1cbc80

hwmon: (da9055) Remove use of regmap_irq_get_virq()

2014-02-07T01:22:33+00:00

Remove use of regmap_irq_get_virq() in driver probe which was
conflicting with use of platform_get_irq_byname().
platform_get_irq_byname() already returns the VIRQ number due
to MFD core translation so using regmap_irq_get_virq() on that
returned value results in an incorrect IRQ being requested.
The driver probes then fail because of this.

hwmon: (pmbus) Support per-page exponent in linear mode

2014-02-03T05:21:40+00:00

Some chips use different exponents for sensors on different pages
or rails. Detect and store exponent per page to support this situation.

This fixes a problem with wrong voltages seen on UCD90120.

hwmon: Fix SENSORS_TMP102 dependencies to eliminate build errors

2014-02-02T16:59:07+00:00

Similar to what was done for the lm75 driver.

Add depends on THERMAL since that is what provides the
register/unregister functions above, but only if THERMAL_OF was
selected as this is an optional feature of the driver.

hwmon: Fix SENSORS_LM75 dependencies to eliminate build errors

2014-02-02T16:59:07+00:00

Based on an earlier attempt by Randy Dunlap.

Fix SENSORS_LM75 dependencies to eliminate build errors:

drivers/built-in.o: In function `lm75_remove':
lm75.c:(.text+0x12bd8c): undefined reference to `thermal_zone_of_sensor_unregister'
drivers/built-in.o: In function `lm75_probe':
lm75.c:(.text+0x12c123): undefined reference to `thermal_zone_of_sensor_register'

Add depends on THERMAL since that is what provides the
register/unregister functions above, but only if THERMAL_OF was
selected as this is an optional feature of the driver.

hwmon: (it87) Print proper names for the IT8771E and IT8772E

2014-01-29T19:40:08+00:00

The driver prints IT8771F and IT8772F instead of IT8771E and IT8772E
respectively when the driver is loaded. This is a cosmetic only bug
but let's fix it.
