Kernel contains QSPI driver strongly tied to MTD and nor-flash memory. New spi-mem interface allows usage also other memory types, especially much larger NAND with SPI interface. This driver works as SPI controller and is not related to MTD, however can work with NAND-flash or other peripherals using spi-mem interface.This is fine from a SPI point of view
Cool. There are still 2 things I think should be addressed before merging the driver: 1/ Fixing the SoB tag to match the author (problem reported by Alexandre) 2/ Getting this patch [1] merged and implementing the ->get_name() hook in this driver so that SPI NOR devs declared to the MTD layer keep the same name after the transition to spi-mem and mtdparts= passed on the cmdline keep working. Without this in place we're likely to break a few setups :-/.
but I'd like to apply it directly to the SPI tree rather than ack it for merge via the MTD tree - can we work something out with a shared branch or something?
Sure, I can provide an immutable tag for you to pull and I'll add my acks on those patches once the 2 things I mentioned above are addressed. Regards, Boris [1]https://patchwork.kernel.org/patch/10508693/
