I am asking because this node name is used by the driver as device name which is how it also appears in sysfs. Reason for that being that "main-eeprom" and "dds-eeprom" (second EEPROM in the system) are easier to rembmer and tell apart than "eeprom@a4" and "eeprom@a5". Granted, I can divorce naming scheme in the driver from device node name, but then I'd have to keep a "address -> deivce name" lookup table which I was hoping to avoid. > >> + compatible = "zii,rave-sp-eeprom"; >> + reg = <0xA4 0x4000>; > > lowercase hex please.
