2018-07-08hwmon: Document the sensor enable attributeShilpasri G Bhat
Document new ABI attributes: in[0-*]_enable fan[1-*]_enable temp[1-*]_enable curr[1-*]_enable power[1-*]_enable energy[1-*]_enable humidity[1-*]_enable Signed-off-by: Shilpasri G Bhat <shilpa.bhat@linux.vnet.ibm.com> [groeck: Updated commit text, removed unnecessary details from ABI description] Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-01-25hwmon: Update documentation to clarify rules for the 'name' attributeGuenter Roeck
Clarify that the name attribute must report a valid name, and the rules for valid names. Also clarify that the name parameter must be provided for all supported API functions. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-25hwmon: Document temp[1-*]_min_hyst sysfs attributeJean Delvare
The temp[1-*]_min_hyst sysfs attribute is already implemented by 3 hwmon drivers (adt7x10, lm77 and lm92) but was missing from the standard interface. Also add temp[1-*]_lcrit_hyst for consistency, even though no driver implement that one for the time being.

2013-01-25hwmon: Retire SENSORS_LIMITGuenter Roeck
SENSORS_LIMIT and clamp_val have the same functionality, so retire SENSORS_LIMIT as it is no longer needed. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
2012-01-16hwmon: (sysfs-interface) Update tempX_type attribute to be more genericGuenter Roeck
The temp[1-*]_type attribute reports the temperature sensor type. Sensor type 1 is described as "PII/Celeron Diode", which is quite restrictive; other CPUs may also have an embedded temperature sensor diode with similar characteristics. Change description to "CPU embedded diode" to be more generic. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2010-08-14hwmon: Remove in[0-*]_fault from sysfs-interfaceJean Delvare
Fault files are for hardware failures that can be reported. So far we've seen chips reporting such failures for temperature sensors and fans, but not for voltages. Remove in[0-*]_fault for now. It can be added back later if really needed, but I doubt it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>

2007-07-19hwmon: Fault files naming conventionJean Delvare
We have the following naming convention documented in Documentation/hwmon/sysfs-interface for fault files: in[0-*]_input_fault fan[1-*]_input_fault temp[1-*]_input_fault Some drivers follow this convention (lm63, lm83, lm90, smsc47m192). However some drivers omit the "input" part and create files named fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic" libsensors follows this second (non-standard) convention, so it fails to report fault conditions for drivers which follow the standard. We want a single naming scheme, and everyone seems to prefer the shorter variant, so let's go for it. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2006-06-22[PATCH] hwmon: Add sysfs interface for individual alarm filesJean Delvare
Extend the sysfs interface of hardware monitoring chips, by adding individual alarm and beep files. Contrary to the old aggregated "alarms" and "beeps" files, individual files constitute a standard way to access the status information, making it finally possible to implement a chip-independant hardware monitoring chip access library (once all drivers have been added this new interface, that is.) If future drivers need more individual files, the interface will be extended as needed at the same time these drivers are merged into the kernel tree.

2006-02-06[PATCH] hwmon: New f71805f driverJean Delvare
This is my f71805f hardware monitoring driver ported from lm_sensors to Linux 2.6. This new driver differs from the other hardware monitoring drivers in that it is implemented as a platform driver. This might not be optimal yet (we would probably need a generic infrastructure and bus type for Super-I/O logical devices) but it is certainly much better than the i2c-isa solution. Note that this driver requires lm_sensors CVS. I hope to get it released as 2.10.0 soon. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] hwmon: Add PEC support to the lm90 driverJean Delvare
Add PEC support to the lm90 driver. Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").

2005-07-11[PATCH] I2C: Move hwmon drivers (3/3)Jean Delvare

Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace.
