    1011013. This is the bank_pin name that can be used in U-Boot (see [wiki:gpio#uboot here])
    1021024. This is the name provided to Linux via gpio-line-names in the device-tree (see [wiki:gpio#gpiolib here])
    103 5. Any of the above pin function assignments can be altered by changing the device-tree to change the pinmux which is also where you can specify drive strength, pull-up, pull-down etc.
