Some hardware does that. That's what OHCI, EHCI, UHCI, XHCI, SDHCI, and similar are all about. It always helps when well understood hardware follows a register interface. It doesn't work for everything, but I agree it would be good to have preferred hw interfaces for SPI & I2C. g. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
