     751. This is the connector pinout.
     762. This is the signal name from the [http://www.gateworks.com/usermanuals ​Venice hardware manuals]
     773. This is the bank_pin name that can be used in U-Boot (see [wiki:gpio#uboot here])
     784. This is the name provided to Linux via gpio-line-names in the device-tree (see [wiki:gpio#gpiolib here])
     795. 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.
