Hello,

Changes since v2:

  - added changes to enable ICB in DT.

  - addressed DT schema and resource struct review comments.

  - added Venus firmware subnode for non-TZ platform.


v2 can be found at [1].
These changes depend on patch series [2] - [6].

Thanks,
Dikshita

You can drop maxItems. Implied by size of 'items'.

As I said on the other Venus schemas, can you really have 20 IOMMUs 
attached? This is a single SoC, you should know how many are attached.
