7title: Mobileye EyeQ5 pin controller
8
9description: >
10  The EyeQ5 pin controller handles the two pin banks of the system. It belongs
11  to a system-controller block called OLB.
12
13  Pin control is about bias (pull-down, pull-up), drive strength and muxing. Pin
14  muxing supports two functions for each pin: first is GPIO, second is
15  pin-dependent.
16
17  Pins and groups are bijective.
