- * Overlay for the Raspberry Pi GPIO Fan @ BCM GPIO12.
-+ * References:
-+ * - https://www.raspberrypi.org/forums/viewtopic.php?f=107&p=1367135#p1365084
-+ *
- * Optional parameters:
-- * - "gpiopin" - default GPIO12
-- * - "temp" - default 55000
-+ * - "gpiopin" - BCM number of the pin driving the fan, default 12 (GPIO12);
-+ * - "temp" - CPU temperature at which fan is started in millicelsius, default 55000;
-+ *
- * Requires:
-- * - kernel configurations: CONFIG_SENSORS_GPIO_FAN=m and CONFIG_SENSORS_PWM_FAN=m;
-- * - kernel rebuid;
-- * - DC Fan connected to GPIO via a N-MOSFET (2N7002)
-+ * - kernel configurations: CONFIG_SENSORS_GPIO_FAN=m;
-+ * - kernel rebuild;
-+ * - N-MOSFET connected to gpiopin, 2N7002-[https://en.wikipedia.org/wiki/2N7000];
-+ * - DC Fan connected to N-MOSFET Drain terminal, a 12V fan is working fine and quite silently;
