hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37

2015-06-06T15:20:55+00:00

commit 9aecac04d8d89e730ae362a748113b19c06a9d39 upstream.

I2C address 0x37 may be used by EEPROMs, which can result in false
positives. Do not attempt to detect a chip at this address.

hwmon: (ntc_thermistor) Ensure iio channel is of type IIO_VOLTAGE

2015-06-06T15:20:52+00:00

commit adba657533bdd255f7b78bc8a324091f46b294cd upstream.

When configured via device tree, the associated iio device needs to be
measuring voltage for the conversion to resistance to be correct.
Return -EINVAL if that is not the case.

hwmon: (ads7828) Check return value of devm_regmap_init_i2c

2015-02-23T04:10:30+00:00

devm_regmap_init_i2c() can fail, thus add return value checking.

Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

2015-02-19T18:36:45+00:00

Pull kconfig updates from Michal Marek:
 "Yann E Morin was supposed to take over kconfig maintainership, but
  this hasn't happened.  So I'm sending a few kconfig patches that I
  collected:

   - Fix for missing va_end in kconfig
   - merge_config.sh displays used if given too few arguments
   - s/boolean/bool/ in Kconfig files for consistency, with the plan to
     only support bool in the future"

* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kconfig: use va_end to match corresponding va_start
  merge_config.sh: Display usage if given too few arguments
  kconfig: use bool instead of boolean for type definition attributes

hwmon: (tmp102) add hibernation callbacks

2015-02-03T20:17:12+00:00

Setting a dev_pm_ops suspend/resume pair but not a set of
hibernation functions means those pm functions will not be
called upon hibernation.
Fix this by using SIMPLE_DEV_PM_OPS, which appropriately
assigns the suspend and hibernation handlers and move
mp102_suspend/tmp102_resume under CONFIG_PM_SLEEP to avoid
build warnings.

hwmon: (ads2828) Only keep data in device data structure if needed

2015-02-02T16:20:06+00:00

The variables diff_input, ext_vref, and vref_mv are only used in the probe
function and therefore don't need to be kept in the device data structure.

hwmon: (jc42) Allow negative hysteresis temperatures

2015-01-26T05:24:00+00:00

The driver supports negative high and critical limits, it can return
negative hysteresis values, so there is no good reason to not let the
user write negative hysteresis values.
