-Amlogic NAND Flash Controller (NFC) for GXBB/GXL/AXG family SoCs
-
-This file documents the properties in addition to those available in
-the MTD NAND bindings.
-
-Required properties:
-- compatible : contains one of:
-  - "amlogic,meson-gxl-nfc"
-  - "amlogic,meson-axg-nfc"
-
-- reg        : Offset and length of the register set
-
-- reg-names  : "nfc" is the register set for NFC controller and "emmc"
-		is the register set for MCI controller.
-
-- clocks     :
-	A list of phandle + clock-specifier pairs for the clocks listed
-	in clock-names.
-
-- clock-names: Should contain the following:
-	"core" - NFC module gate clock
-	"device" - parent clock for internal NFC
-
-Optional children nodes:
-Children nodes represent the available nand chips.
-
-Other properties:
-see Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings.
-
-Example demonstrate on AXG SoC:
-
-	nand-controller@7800 {
-		compatible = "amlogic,meson-axg-nfc";
-		reg = <0x0 0x7800 0x0 0x100>,
-		      <0x0 0x7000 0x0 0x800>;
-		reg-names = "nfc", "emmc";
-		#address-cells = <1>;
-		#size-cells = <0>;
-		interrupts = <GIC_SPI 34 IRQ_TYPE_EDGE_RISING>;
-
-		clocks = <&clkc CLKID_SD_EMMC_C>,
-			 <&clkc CLKID_FCLK_DIV2>;
-		clock-names = "core", "device";
-
-		pinctrl-names = "default";
-		pinctrl-0 = <&nand_pins>;
-
-		nand@0 {
-			reg = <0>;
-			#address-cells = <1>;
-			#size-cells = <1>;
-
-			nand-on-flash-bbt;
-		};
-	};
