2019-04-15hwmon: Add support for samples attributesGuenter Roeck1-0/+10
Add support for the new samples attributes to the hwmon core. Cc: Krzysztof Adamski <[email protected]> Cc: Nicolin Chen <[email protected]> Acked-by: Nicolin Chen <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2019-04-15hwmon: Add convience macro to define simple static sensorsCharles Keepax1-0/+8
It takes a fair amount of boiler plate code to add new sensors, add a macro that can be used to specify simple static sensors. Signed-off-by: Charles Keepax <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2018-10-10hwmon: (core) Add hwmon_in_enable attributeNicolin Chen1-0/+2
According to hwmon ABI, in%d_enable is a sysfs interface that allows user space to enable and disable the input sensor. So this patch just simply adds the attribute to the list. Signed-off-by: Nicolin Chen <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2018-07-18hwmon: Add helper to tell if a char is invalid in a nameAndrew Lunn1-0/+23
HWMON device names are not allowed to contain "-* \t\n". Add a helper which will return true if passed an invalid character. It can be used to massage a string into a hwmon compatible name by replacing invalid characters with '_'.

2018-07-18hwmon: Add support for power min, lcrit, min_alarm and lcrit_alarmAndrew Lunn1-0/+8
Some sensors support reporting minimal and lower critical power, as well as alarms when these thresholds are reached. Add support for these attributes to the hwmon core.

2018-07-18hwmon: Add missing HWMON_T_LCRIT_ALARM defineAndrew Lunn1-0/+1
The enum hwmon_temp_lcrit_alarm exists, but the BIT definition is missing. Signed-off-by: Andrew Lunn <[email protected]> Acked-by: Guenter Roeck <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-02-28hwmon: (core) Add hwmon_max to hwmon_sensor_types enumerationSudeep Holla1-0/+1
It's useful to know the maximum types of sensor supported by hwmon framework. It can be used to allocate some data structures when sorting the monitors based on their type. This will be used by scmi hwmon support. Cc: [email protected] Acked-by: Guenter Roeck <[email protected]> Signed-off-by: Sudeep Holla <[email protected]>
2017-04-02hwmon: Constify str parameter of hwmon_ops->read_stringJean Delvare1-1/+1
The read_string callback is supposed to retrieve a pointer to a constant string. Signed-off-by: Jean Delvare <[email protected]> Reviewed-by: Peter Huewe <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2017-03-22hwmon: Add missing HWMON_T_ALARMPeter Huewe1-0/+1
Unfortunately the HWMON_T_ALARM define was missing, although the associated entry was present in hwmon_temp_attributes. This is needed to convert drivers to the new interface which use channel based alarms. Signed-off-by: Peter Huewe <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2016-12-09hwmon: (core) Rename groups parameter in API to extra_groupsGuenter Roeck1-4/+4
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. Signed-off-by: Guenter Roeck <[email protected]>
2016-12-09hwmon: (core) Deprecate hwmon_device_register()Guenter Roeck1-0/+2
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. Signed-off-by: Guenter Roeck <[email protected]>
2016-12-09hwmon: (core) Add support for string attributes to new APIGuenter Roeck1-2/+17
The new API is so far only suited for data attributes and does not work well for string attributes, specifically for the 'label' attributes. Provide a separate callback function for those. Signed-off-by: Guenter Roeck <[email protected]>
2016-12-09hwmon: (core) Clarify when read and write callbacks are mandatoryGuenter Roeck1-4/+2
The callback descrption in hwmon.h was misleading and stated that read and write callbacks would be optional. More accurate is is that the callbacks are mandatory if readable / writeable attributes are present. Signed-off-by: Guenter Roeck <[email protected]>
2016-09-08hwmon: (core) Add basic pwm attribute support to new APIGuenter Roeck1-0/+13

2016-09-08hwmon: (core) New hwmon registration APIGuenter Roeck1-0/+148
Up to now, each hwmon driver has to implement its own sysfs attributes. This requires a lot of template code, and distracts from the driver's core function to read and write chip registers. To be able to reduce driver complexity, move sensor attribute handling and thermal zone registration into hwmon core. By using the new API, driver code and data size is typically reduced by 20-70%, depending on driver complexity and the number of sysfs attributes supported. With this patch, the new API only supports thermal sensors. Support for other sensor types will be added with subsequent patches.

2013-10-13hwmon: Provide managed hwmon registrationGuenter Roeck1-0/+5
Drivers using the new hwmon_device_register_with_groups API often have a remove function which consists solely of a call hwmon_device_unregister(). Provide support for devm_hwmon_device_register_with_groups and devm_hwmon_device_unregister to allow this repeated code to be removed and help eliminate error handling code.

2013-10-13hwmon: Introduce hwmon_device_register_with_groupsGuenter Roeck1-0/+5
hwmon_device_register_with_groups() lets callers register a hwmon device together with all sysfs attributes in a single call. When using hwmon_device_register_with_groups(), hwmon attributes are attached to the hwmon device directly and no longer with its parent device. Signed-off-by: Guenter Roeck <[email protected]>
2013-01-25hwmon: Retire SENSORS_LIMITGuenter Roeck1-12/+0
SENSORS_LIMIT and clamp_val have the same functionality, so retire SENSORS_LIMIT as it is no longer needed. Signed-off-by: Guenter Roeck <[email protected]> Acked-by: Jean Delvare <[email protected]>
2012-03-16device.h: audit and cleanup users in main include dirPaul Gortmaker1-1/+1
The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <[email protected]>
