Macronix Raw NAND Controller Device Tree Bindings

-------------------------------------------------

Required properties:

- compatible: should be "mxic,multi-itfc-v009-nand-controller"

- reg: should contain 1 entry for the registers

- #address-cells: should be set to 1

- #size-cells: should be set to 0

- interrupts: interrupt line connected to this raw NAND controller

- clock-names: should contain "ps", "send" and "send_dly"

- clocks: should contain 3 phandles for the "ps", "send" and

	 "send_dly" clocks

Children nodes:

- children nodes represent the available NAND chips.

See Documentation/devicetree/bindings/mtd/nand-controller.yaml

for more details on generic bindings.

Example:

	nand: nand-controller@43c30000 {

		compatible = "mxic,multi-itfc-v009-nand-controller";

		reg = <0x43c30000 0x10000>;

		#address-cells = <1>;

		#size-cells = <0>;

		interrupts = <GIC_SPI 0x1d IRQ_TYPE_EDGE_RISING>;

		clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>;

		clock-names = "send", "send_dly", "ps";

		nand@0 {

			reg = <0>;

			nand-ecc-mode = "soft";

			nand-ecc-algo = "bch";

		};

	};
