I would expect that most controllers would look just the same as they do now except for the additional ability to do quad transfers - it'd just get told that some transfers should use more data lines.
The SPI is about the byte streams, but the dummy may be not a byte, the dummy maybe just 4bit.
It is interesting to handle the dummy issue for the future's SPI controller.
I don't know what you mean by "the dummy". -------------- next part -------------- A non-text attachment was scrubbed...
