hwmon: (core) Rename groups parameter in API to extra_groups

2016-12-10T05:54:22+00:00

The 'groups' parameter of hwmon_device_register_with_info() and
devm_hwmon_device_register_with_info() is only necessary if extra
non-standard attributes need to be provided. Rename the parameter
to extra_groups and clarify the documentation.

hwmon: (core) Deprecate hwmon_device_register()

2016-12-10T05:54:19+00:00

Inform the user that hwmon_device_register() is deprecated,
and suggest conversion to the newest API. Also remove
hwmon_device_register() from the kernel API documentation.

Note that hwmon_device_register() is not marked as __deprecated()
since doing so might result in build errors.

hwmon: (core) Clarify use of chip attributes

2016-12-10T05:54:18+00:00

Describing chip attributes as "attributes which apply to the entire chip"
is confusing. Rephrase to "attributes which are not bound to a specific
input or output".

Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate
that the respective strings strings are not templates but actual attribute
names.

The previous patch renamed several files that are cross-referenced
along the Kernel documentation. Adjust the links to point to
the right places.

hwmon: (max6650) Allow fan shutdown and initial rpm target

2016-09-09T04:34:17+00:00

The fan can be stopped by writing "3" to pwm1_enable in sysfs.

Add devicetree property for early initialization of the fan controller
to prevent overheating, for example when resetting the board while the
fan was completely turned off.

Also improve error reporting, I2C failures were ignored while writing
new values.

hwmon: (ucd9000) Add support for UCD90160 Power Supply Sequencer

2016-09-09T04:34:16+00:00

The UCD90160 Power Supply Sequencer reuses the existing register layout,
so just an id addition was required.
