title: Mobileye EyeQ5 pin controller

description: >
  The EyeQ5 pin controller handles the two pin banks of the system. It belongs
  to a system-controller block called OLB.

  Pin control is about bias (pull-down, pull-up), drive strength and muxing. Pin
  muxing supports two functions for each pin: first is GPIO, second is
  pin-dependent.

  Pins and groups are bijective.
