[PATCH 06/11] reset: eyeq: add platform driver

Théo Lebrun
2024-04-10T17:12:38Z

Add Mobileye EyeQ reset controller driver, for EyeQ5, EyeQ6L and EyeQ6H
SoCs. Instances belong to a shared register region called OLB.

There is one OLB instance for EyeQ5 and EyeQ6L. There are seven OLB
instances on EyeQ6H; three have a reset controller embedded:
- West and east get handled by the same compatible.
- Acc is another one.

Each instance vary in the number and types of reset domains.

+ * one-bit-per-reset, status detection method, busywait duration, etc.
