Here are some examples (kernel 4.17):
$ cd /sys/bus/nd/devices/nmem0/nfit
$ grep -s . *
device:0x314e
dsm_mask:0x3c76
family:1
flags:smart_notify
format:0x0101
formats:1
handle:0x1
id:802c-0f-1612-122f8255 [SPD bytes 320-328, in that order left-to-right]
phys_id:0x16
rev_id:0x3100
serial:0x122f8255
subsystem_device:0x3141
subsystem_rev_id:0x0100
subsystem_vendor:0x8034 [Cypress Semiconductor]
vendor:0x802c [Micron]
$ cd /sys/bus/nd/devices/nmem1/nfit
$ grep -s . *
