I was waiting to verify the changes and ensure all the suggested updates were properly incorporated. The effort was further delayed due to some slave-side setup issues. I have now addressed and validated all the suggested changes except one, which I have responded to separately below.

Right now, i only want to add plain i3c controller support without IBI hence. I shall add expanded reg while adding i3c support. For now, its not required. Please let me know if this is fine for now. > Konrad
