+title: Mobileye EyeQ5 pinctrl (pinmux & pinconf) controller
+
+description:
+ The EyeQ5 pin controller handles a pin bank. It is custom to this platform,
+ its registers live in a shared region called OLB.
+ There are two pin banks on the platform, each having a specific compatible.
+ Pins and groups are bijective.
