-* NXP LPC18xx EEPROM memory NVMEM driver
-
-Required properties:
-  - compatible: Should be "nxp,lpc1857-eeprom"
-  - reg: Must contain an entry with the physical base address and length
-    for each entry in reg-names.
-  - reg-names: Must include the following entries.
-    - reg: EEPROM registers.
-    - mem: EEPROM address space.
-  - clocks: Must contain an entry for each entry in clock-names.
-  - clock-names: Must include the following entries.
-    - eeprom: EEPROM operating clock.
-  - resets: Should contain a reference to the reset controller asserting
-    the EEPROM in reset.
-  - interrupts: Should contain EEPROM interrupt.
-
-Example:
-
-  eeprom: eeprom@...0e000 {
-    compatible = "nxp,lpc1857-eeprom";
-    reg = <0x4000e000 0x1000>,
-          <0x20040000 0x4000>;
-    reg-names = "reg", "mem";
-    clocks = <&ccu1 CLK_CPU_EEPROM>;
-    clock-names = "eeprom";
-    resets = <&rgu 27>;
-    interrupts = <4>;
-  };
