    Subject[PATCH 03/11] dt-bindings: reset: mobileye,eyeq5-reset: add EyeQ6L and EyeQ6H
    Add bindings for EyeQ6L and EyeQ6H reset controllers.

    Some controllers host a single domain, meaning a single cell is enough.
    We do not enforce reg-names for such nodes.

    - shared region called OLB.
    + EyeQ reset controller handles one or more reset domains. They live in shared
    + regions called OLB. EyeQ5 and EyeQ6L host one OLB each, each with one reset
    + instance. EyeQ6H hosts 7 OLB regions; three of those (west, east,
    + accelerator) host reset controllers. West and east are duplicates.
