+Date:		July 2025
+KernelVersion:	6.17
+Contact:	"Derek J. Clark" <derekjohn.clark@gmail.com>
+Description:
+		This sets the PWM fan mode of operation. Valid values are [0-3].
+    Values [0-2] conform with standard hwmon operating modes. Value 3
+    enables user defined fan curve settings.
+
+    Applies to Ayn Loki and Toctoy Zeenix lines of handheld devices.

+What:		/sys/class/hwmon/hwmon[0-9]/pwm1_auto_point[1-5]_pwm
+Date:		July 2025
+KernelVersion:	6.17
+Contact:	"Derek J. Clark" <derekjohn.clark@gmail.com>
+Description:
+		This sets the PWM fan duty cycle for the given index of the fan curve.
+    When the temperature reaches the corresponding pwm1_auto_point[1-5]_temp,
+    the EC will automatically increase the fan duty cycle to the given value.
+
+    Values are [0-255]
+
+    Applies to Ayn Loki and Toctoy Zeenix lines of handheld devices.

+Description:
+		This sets the activation temperature for the given index of the fan curve.
+    When the temperature reaches the given value, the EC will automatically
+    increase the fan duty cycle to the corresponding pwm1_auto_point[1-5]_pwm
