ABI: sysfs-class-hwmon: add descriptions for humidity min/max alarms

2024-02-25T20:37:37Z

This attributes have been recently introduced and require the corresponding ABI documentation. Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240130-topic-chipcap2-v6-3-260bea05cf9b@gmail.com Signed-off-by: Guenter Roeck

hwmon: add fault attribute for voltage channels

2024-02-11T21:43:09Z

Sometimes a voltage channel might have an hard failure (eg: a shorted MOSFET). Hence, add a fault attribute to report such failures. Signed-off-by: Nuno Sa Link: https://lore.kernel.org/r/20240129-b4-ltc4282-support-v4-2-fe75798164cc@analog.com Signed-off-by: Guenter Roeck

ABI: sysfs-class-hwmon: document emergency/max/min temperature alarms

2023-12-11T14:21:00Z

These attributes are widely used in the hwmon subsystem, but they still must be documented. Add tempY_emergency_alarm, tempY_max_alarm and tempY_min_alarm to the ABI documentation according to their current usage and access rights in the hwmon subsystem.

ABI: sysfs-class-hwmon: fix tempY_crit_alarm access rights

2023-12-11T14:21:00Z

This attribute is defined as read-only by all drivers that support it. It seems that the access rights and description for this attribute were copied from the intrusionY_alarm, which has indeed RW rights and must be cleared by the user. These are the modules that currently use this attribute: - adt7x10 - i5500_temp - jc42 - lm83 - lm90 - lm95245 - max31760 - max6621 - mc34vr500 - tmp401 - tmp464 - tmp513 Fix the attribute description and make it read-only.

ABI: sysfs-class-hwmon: document missing humidity attributes

2023-12-11T14:21:00Z

All these attributes already exist and are used by the hwmon subsystem, but they still must be documented. The missing attributes are the following: - humidityY_alarm - humidityY_fault - humidityY_label - humidityY_max - humidityY_max_hyst - humidityY_min - humidityY_min_hyst Add the missing humidity attributes to the ABI documentation according to their current usage and access rights in the hwmon subsystem.

ABI: sysfs-class-hwmon: rearrange humidity attributes alphabetically

2023-12-11T14:21:00Z

Preliminary step to add the missing humidity attributes in the ABI documentation. Adding new elements alphabetically is a common practice that has been loosely followed in the sysfs-class-hwmon documentation. Since most of the humidity attributes must be added to the file, a single attribute needs to be rearranged to reinforce alphabetical order.

hwmon: (pmbus) Move pec attribute to I2C device

2022-07-13T15:38:17Z

Enabling and disabling PEC for PMBus devices is currently only supported with a debugfs attribute, which requires debugfs to be enabled and is thus less than perfect. Take the lm90 driver as example and add a 'pec' attribute to the I2C device if both the I2C adapter and the PMBus device support it. Remove the now obsolete 'pec' attribute from debugfs.

ABI: hwmon: Document "label" sysfs attribute

Add the "label" sysfs attribute, which can contain a descriptive label that allows to uniquely identify a device within the system. Signed-off-by: Paul Cercueil Link: https://lore.kernel.org/r/20220110182256.30763-2-paul@crapouillou.net Signed-off-by: Guenter Roeck
