I can of course split my patch into individual ones and resubmit them, but as you already have the entire patch set ready, I feel like we can just push those. I looked through your changes and it seems like you covered all the subsystems. Please let me know if there is something else I should do.

My intention here was to first add the _WO attribute so that afterwards I can add a new bus attribute in the fsl-mc bus.
