24 +MTK Smart Device SoCs NAND controller DT binding
25 +
26 +Required properties:
27 +- compatible: Should be "mediatek,mt2701-nfc".
28 +- reg: The first contains base physical address and size of
29 + NAND controller's registers. The second contains base
30 + physical address and size of NAND ECC engine.
31 +- interrupts: the NFC NFI interrupt, and the NFC ECC interrupt
32 +- clocks: NAND controller clocks.
33 +- clock-names: NAND controller clocks internal name.
34 +- vmch-supply: NAND power supply.
35 +- #address-cells: Partition address, should be set 1.
36 +- #size-cells: Partition size, should be set 1.
37 +
38 +Optional properties:
39 +
40 +nand-on-flash-bbt: Use a flash based bad block table.
41 +
42 +Optional subnodes:
43 +- Partitions, see Documentation/devicetree/bindings/mtd/partition.txt
44 +
45 +Example:
46 +
47 + nand: nand@1100d000 {
48 + compatible = "mediatek,mt2701-nfc";
49 + reg = <0 0x1100d000 0 0x1000>, <0 0x1100e000 0 0x1000>;

52 + clocks = <&pericfg CLK_PERI_NFI>, <&pericfg CLK_PERI_NFI_ECC>,
53 + <&pericfg CLK_PERI_NFI_PAD>;
54 + clock-names = "nfi_ck", "nfi_ecc_ck", "nfi_pad_ck";

56 + status = "disabled";
57 + #address-cells = <1>;
