Really?  I went to the link in your message, filled out the stupid
information box that your company has now decided to start spamming
me with, and I got a 2-page brochure telling me how wonderful it was.
It's *called* a datasheet.  Even right there in its name: dwc_mipi_i3c_ds.pdf
It's not a data sheet.

A big missing feature like that is probably worth mentioning in a comment.
eg: TODO: DMA support.
