- When scsi controller acts as a bus, we need to bind its children scsi devices(scsi hdd, cd, dvd, scanner) to their drivers as spi controller binds spi flashes, so scsi-uclass's post bind function calls dm_scan_fdt_dev() to bind scsi subnode devices;
- When scsi controller is a Serial Attached SCSI, it can also work as a pure controller as an on-board component on the motherboard, it may has no subnodes in fdt, then dm_scan_fdt_dev() does nothing and has no effect.
