So, this is the way drivers/mtd/altera_qspi.c getting probed? > > Normally, devices are probed when they are used.

True, suppose if I wanted to probe spi-flash MTD uclass drivers w/o using "commands" like sf probe then I need to implement dm_scan node logic on mtd-uclass.c correct? thanks! -- Jagan.
