6 Required properties:
7 - compatible: Should be set to "fsl,vf610-nfc"
8 - reg: address range of the NFC.
9 - interrupts: interrupt of the NFC.
10 - #address-cells: shall be set to 1. Encode th
11 - #size-cells : shall be set to 0.
12 - assigned-clocks: main clock from the SoC, fo
13 - assigned-clock-rates: The NAND bus timing is
14 rate and should not exceed maximum timing
15 in a board stuffing. Typical NAND memory t
