Note 1: The Linux export number is the number under which is the GPIO mapped and accessible in Linux; for more details see the i.MX 8M Mini general GPIO section
Note 2: the PADs are configured by both - u-boot and Linux, in the very same way by default; the configuration data is in the u-boot and Linux device tree files
Note 3: For more information about processor PAD configuration see the i.MX 8M Mini Applications Processor Reference Manual
