+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";
- };

Maybe it is unused and should be dropped instead. But otherwise, the schema looks good. Rob
