But tell me why first ? You said it needs to work with any controller.
And now you say I need to change it to some controller_specific ptr,
won't that make it controller specific protocol ?

You responded on something you wanted ignoring all the other parts,
still waiting for those response.

1. Tell me how my changes to MHU and SCMI are related ?
2. How my MHU changes and PCC are different ? Why do you think
   this SCMI is FUBAR design which the clients using PCC are not ?
