Subject: [RFC 11/11] ABI: sysfs-class-hwmon: Add missing hwmon standard attributes
Add definitions for the following non-deprecated standard
attributes implemented in the API and mentioned in the sysfs
interface spec but not found in the ABI documentation.
Alarm attributes:
* inY_alarm, inY_min_alarm, inY_max_alarm,
inY_lcrit_alarm, inY_crit_alarm
* currY_alarm, currY_min_alarm, currY_max_alarm,
currY_lcrit_alarm, currY_crit_alarm
* powerY_alarm, powerY_cap_alarm,
powerY_max_alarm, powerY_crit_alarm
* fanY_alarm, fanY_min_alarm, fanY_max_alarm
* tempY_alarm, tempY_min_alarm, tempY_max_alarm,
tempY_lcrit_alarm, tempY_emergency_alarm
(tempY_crit_alarm already existed)
Beep attributes:
beep_enable, inY_beep, currY_beep, fanY_beep, tempY_beep
Sample average attributes:
samples, in_samples, power_samples, temp_samples, curr_samples
Fault attributes:
tempY_fault (fanY_fault already existed)
