23 cases, <linux/hwmon-sysfs.h>. linux/hwmon.h declares the following
73 names. Device names including invalid characters (whitespace, '*', or '-')
89 --------------------------------------------
99 `const struct attribute_group **extra_groups` 	Null-terminated list of additional non-standard
118 	NULL-terminated list of device channel descriptors.
145 Each sensor channel is described with struct hwmon_channel_info, which is
156     The hardware monitoring sensor type.
158     Supported sensor types are
161      hwmon_chip		A virtual sensor type, used to describe attributes
163      hwmon_temp		Temperature sensor
164      hwmon_in		Voltage sensor
165      hwmon_curr		Current sensor
166      hwmon_power		Power sensor
167      hwmon_energy	Energy sensor
168      hwmon_humidity	Humidity sensor
169      hwmon_fan		Fan speed sensor
174     Pointer to a 0-terminated list of configuration values for each
175     sensor of the given type. Each value is a combination of bit values
176     describing the attributes supposed by a single sensor.

325 Driver-provided sysfs attributes
326 --------------------------------
330 Only additional non-standard sysfs attributes need to be provided.
332 The header file linux/hwmon-sysfs.h provides a number of useful macros to
338 additional information such as a sensor index which will need to be passed
