I only quickly went through the patches you sent and saying it's a repost of the RFC is a bit of a lie. You completely ignored the state tracking I was trying to do to avoid leaving the flash in 8D mode when suspending/resetting the board, and I think that part is crucial. If I remember correctly, we already had this discussion so I must say I'm a bit disappointed. Can you sync with Pratyush? I think his series [1] is better in that it tries to restore the flash in single-SPI mode before suspend (it's missing the shutdown case, but that can be easily added I think). Of course that'd be even better to have proper state tracking at the SPI NOR level. Regards, Boris [1]https://lkml.org/lkml/2020/3/13/659
