hwmon: (nct7802) Add auto_point attributes
Introduced REG_PWM, pwm[1..3]_auto_point[1..5]_temp, pwm[1..3]_auto_point[1..5]_pwm, nct7802_auto_point_attrs, nct7802_auto_point_group, updated nct7802_regmap_is_volatile Signed-off-by: Constantine Shulyupin <const@MakeLinux.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

@ -17,8 +17,7 @@ This driver implements support for the Nuvoton NCT7802Y hardware monitoring
|
|||
chip. NCT7802Y supports 6 temperature sensors, 5 voltage sensors, and 3 fan
|
||||
speed sensors.
|
||||
|
||||
The chip also supports intelligent fan speed control. This functionality is
|
||||
not currently supported by the driver.
|
||||
Smart Fan™ speed control is available via pwmX_auto_point attributes.
