+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";
-		};
-	};
