Maybe we should drop the > wording about VF610 here since there a separate DSPI driver for Vybrid > as well: https://git.pengutronix.de/cgit/barebox/tree/drivers/spi/Kconfig?h=next#n90 So there already is a driver for this hardware in barebox. I missed that :( I dropped the wording about VF610 for now, but the real solution should be to use the existing driver or at least merge them. I'll see when and if I can find time for this.
