It does add a duplicate driver for the same compatible strings. The current working driver is in 'drivers/mtd/spi-nor/cadence-quadspi.c'. In fact, the compatible string "cdns,qspi-nor" copied from the old driver to this new driver is *only* used for altera. TI has its own compatible string, the new Intel platform adds its own as well. As long as that one doesn't get removed, I have nothing against this driver here. I'm only concerned that this will get forgotten. And given that I added altera guys to the loop in one of the previous versions, I just was surprised they aren't on CC in this version. I'm not familiar with whom to CC for Linux drivers, so sorry for the noise if I'm overreacting here, just tell me. Regards, Simon
