-  * 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;
-+ *      [https://www.tme.eu/en/details/ee40101s1-999-a/dc12v-fans/sunon/ee40101s1-1000u-999/]
