title: Macronix Raw NAND Controller



maintainers:

  - Mason Yang <masonccyang@mxic.com.tw>



description:

  The Macronix Multi-Interface Raw NAND Controller is a versatile flash

  memory controller for embedding in SoCs, capable of interfacing with

  various NAND devices. It requires dedicated clock inputs for core, data

  transmit, and delayed transmit paths along with register space and an

  interrupt line for operation.

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";

		};

	};
