+- compatible: must be "marvell,prestera"
53
+- base-mac-provider: describes handle to node which provides base mac address,
54
+ might be a static base mac address or nvme cell provider.
55

56
+Example:
57
+
58
+eeprom_mac_addr: eeprom-mac-addr {
59
+ compatible = "eeprom,mac-addr-cell";
60
+ status = "okay";
