Thanks for this pointer. So for Multiport, can I do it this way:

1. Core bindings and Core driver changes in one series. Now that we 
finalized we don't be adding the ctrl_irq[1] as discussed on:
https://lore.kernel.org/all/ZU33uWpStIobzyd6@hovoldconsulting.com/.

2. QC bindings and QC driver changes for Multiport to be pushed after we 
clean up the current driver and DT's (an effort which is going on 
currently).

Krishna,
