hwmon: (core) Add support for humidity min/max alarm

2024-02-25T20:37:37+00:00

Add min_alarm and max_alarm attributes for humidityX to support devices that can generate these alarms. Such attributes already exist for other magnitudes such as tempX. Tested with a ChipCap 2 temperature-humidity sensor. Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240130-topic-chipcap2-v6-2-260bea05cf9b@gmail.com Signed-off-by: Guenter Roeck

hwmon: add fault attribute for voltage channels

2024-02-11T21:43:09+00:00

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

hwmon: put HWMON_CHANNEL_INFO() initializers in rodata

2024-02-11T21:43:08+00:00

HWMON_CHANNEL_INFO() is supposed to be used as initializer for arrays of const struct hwmon_channel_info *. However, without explicit const, HWMON_CHANNEL_INFO() creates mutable compound literals, and the const pointers point at the mutable data. Add const to place the data in rodata.

hwmon: (core) Add missing beep-related standard attributes

2023-06-08T13:41:17+00:00

beep_enable, inX_beep, currX_beep, fanX_beep, and tempX_beep are standard attributes mentioned in the sysfs interface specification but not implemented in the hwmon core. Since these are not deprecated, implement them. Adding beep_mask is not necessary, as it is deprecated and the drivers already using it are manually defining it.

hwmon: constify pointers to hwmon_channel_info

2023-04-07T15:45:17+00:00

HWmon core receives an array of pointers to hwmon_channel_info and it does not modify it, thus it can be array of const pointers for safety. This allows drivers to make them also const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Guenter Roeck

hwmon: Deprecate [devm_]hwmon_device_register_with_groups

2023-02-16T19:34:19+00:00

Even though the hardware monitoring documentation already stated that new drivers should use [devm_]devm_hwmon_device_register_with_info() to register with the hardware monitoring subsystem, we still get submissions for new drivers using the older APIs. There is no benefit to use those APIs. On the contrary, using the older APIs results in substantially larger code size. Explicitly deprecate [devm_]hwmon_device_register_with_groups() to ensure that all new drivers use the latest API. Signed-off-by: Guenter Roeck

hwmon: Introduce hwmon_device_register_for_thermal

2022-05-22T18:32:31+00:00

The thermal subsystem registers a hwmon driver without providing chip or sysfs group information. This is for legacy reasons and would be difficult to change. At the same time, we want to enforce that chip information is provided when registering a hwmon device using hwmon_device_register_with_info(). To enable this, introduce a special API for use only by the thermal subsystem. Acked-by: Rafael J . Wysocki Signed-off-by: Guenter Roeck

hwmon: introduce hwmon_sanitize_name()

2022-05-17T12:52:59+00:00

More and more drivers will check for bad characters in the hwmon name and all are using the same code snippet. Consolidate that code by adding a new hwmon_sanitize_name() function.

hwmon: (core) Add support for pwm auto channels attribute

2022-02-28T01:03:19+00:00

pwm[1-*]_auto_channels_temp is documented as an official hwmon sysfs attribute, yet there is no support for it in the new with_info-API. Fix that. Signed-off-by: Armin Wolf Link: https://lore.kernel.org/r/20220224061210.16452-2-W_Armin@gmx.de Signed-off-by: Guenter Roeck
