Yes, I think this driver's device probing is starting to improve the ID table approach that we currently have, which is why I directed a few comments at it. I don't think it goes far enough to being useful to others yet, though. It employs a few hacks that tie it very closely to its own implementation, and I think this can be improved now, before its methods are entrenched too much. > I do not see this > an an obstacle to st_spi_fsm being integrated earlier though; it's presence in > the kernel would provide another example of a H/W Controller that 'spi-nor' > needs to accommodate. No, I don't think a generally-useful framework will pop up overnight, but I think this driver can be one piece of the puzzle. I await your further responses. Thanks, Brian
