It was based on Google Source Code for Coral Edge TPU Mendel release:
https://coral.googlesource.com/linux-imx/
It was tested on Coral Dev Board using this command:
sudo stress --cpu 4 --timeout 3600

v2:
* Fix underscore in property name;
* Add pinctrl entry for gpio-fan;
* Removes undocumented property;
v3:
* Fix subject pattern;
* Fix order of pinctrl entries;
* Fix MX8MQ_IOMUXC_NAND_CLE_GPIO3_IO5 flags;
* Typo pattern (from "gpiofanp" to "gpiofangrp");
* Fix tabs on MX8MQ_IOMUXC_NAND_CLE_GPIO3_IO5 line;
v4:
* Fix cpu_thermal order;
v5:
* Add missing Reviewed-by;
v6:
* Removes unneeded blank line;
