H A Dw83791d.rst93 See below for the description of the sysfs-interface.
100 The sysfs interface to the global enable is via the sysfs beep_enable file.
103 The sysfs interface to the beep bitmask has migrated from the original legacy
104 method of a single sysfs beep_mask file to a newer method using multiple
105 `*_beep` files as described in `Documentation/hwmon/sysfs-interface.rst`.
108 original legacy method used a single sysfs alarms file containing a bitmap
109 of triggered alarms. The newer method uses multiple sysfs `*_alarm` files
110 (again following the pattern described in sysfs-interface).
