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. > Right now the driver does not support DMA interface which will be added > later as the other missed I3C features. > > What do you suggest to avoid this misunderstanding? A big missing feature like that is probably worth mentioning in a comment. eg: TODO: DMA support.
