Note 1: The Linux export number column is no longer provided, as the /sys/class/gpio subsystem was dropped in the 5.15.32-2.0.0 kernel
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
