-+MTK SoCs NAND FLASH controller (NFC) DT binding
-+
-+This file documents the device tree bindings for MTK SoCs NAND controllers.
-+The functional split of the controller requires two drivers to operate:
-+the nand controller interface driver and the ECC engine driver.
-+
-+The hardware description for both devices must be captured as device
-+tree nodes.
-+
-+1) NFC NAND Controller Interface (NFI):
-+=======================================
-+
-+The first part of NFC is NAND Controller Interface (NFI) HW.
-+Required NFI properties:
-+- compatible:			Should be "mediatek,mtxxxx-nfc".
-+- reg:				Base physical address and size of NFI.
-+- interrupts:			Interrupts of NFI.
-+- clocks:			NFI required clocks.
-+- clock-names:			NFI clocks internal name.
-+- status:			Disabled default. Then set "okay" by platform.
-+- ecc-engine:			Required ECC Engine node.
-+- #address-cells:		NAND chip index, should be 1.
-+- #size-cells:			Should be 0.
-+
-+Example:
-+
-+	nandc: nfi@1100d000 {
-+		compatible = "mediatek,mt2701-nfc";
-+		reg = <0 0x1100d000 0 0x1000>;
-+		interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_LOW>;
-+		clocks = <&pericfg CLK_PERI_NFI>,
-+			 <&pericfg CLK_PERI_NFI_PAD>;
-+		clock-names = "nfi_clk", "pad_clk";
-+		status = "disabled";
-+		ecc-engine = <&bch>;
-+		#address-cells = <1>;
-+		#size-cells = <0>;
-+        };
-+
-+Platform related properties, should be set in {platform_name}.dts:
-+- children nodes:	NAND chips.
-+
-+Children nodes properties:
-+- reg:			Chip Select Signal, default 0.
-+			Set as reg = <0>, <1> when need 2 CS.
-+Optional:
-+- nand-on-flash-bbt:	Store BBT on NAND Flash.
-+- nand-ecc-mode:	the NAND ecc mode (check driver for supported modes)
-+- nand-ecc-step-size:	Number of data bytes covered by a single ECC step.
-+			The controller only supports 512 and 1024.
-+			For large page NANDs ther recommended value is 1024.
-+- nand-ecc-strength:	Number of bits to correct per ECC step.
-+			The valid values that the controller supports are: 4, 6,
-+			8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 32, 36, 40, 44,
-+			48, 52, 56, 60.
-+			The strength should be calculated as follows:
-+			E = (S - F) * 8 / 14
-+			S = O / (P / Q)
-+				E :nand-ecc-strength;
-+				S :spare size per sector;
-+				F : FDM size, should be in the range [1,8].
-+				    It is used to store free oob data.
-+				O : oob size;
-+				P : page size;
-+				Q :nand-ecc-step-size
-+			If the result does not match any one of the listed
-+			choices above, please select the smaller valid value from
-+			the list.
-+			(otherwise the driver will do the clamping at runtime).
-+- vmch-supply:		NAND power supply.
-+- pinctrl-names:	Default NAND pin GPIO setting name.
-+- pinctrl-0:		GPIO setting node.
-+
-+Example:
-+	&pio {
-+		nand_pins_default: nanddefault {
-+			pins_dat {
-+				pinmux = <MT2701_PIN_111_MSDC0_DAT7__FUNC_NLD7>,
-+					 <MT2701_PIN_112_MSDC0_DAT6__FUNC_NLD6>,
-+					 <MT2701_PIN_114_MSDC0_DAT4__FUNC_NLD4>,
-+					 <MT2701_PIN_118_MSDC0_DAT3__FUNC_NLD3>,
-+					 <MT2701_PIN_121_MSDC0_DAT0__FUNC_NLD0>,
-+					 <MT2701_PIN_120_MSDC0_DAT1__FUNC_NLD1>,
-+					 <MT2701_PIN_113_MSDC0_DAT5__FUNC_NLD5>,
-+					 <MT2701_PIN_115_MSDC0_RSTB__FUNC_NLD8>,
-+					 <MT2701_PIN_119_MSDC0_DAT2__FUNC_NLD2>;
-+				input-enable;
-+				drive-strength = <MTK_DRIVE_8mA>;
-+				bias-pull-up;
-+			};
-+
-+			pins_we {
-+				pinmux = <MT2701_PIN_117_MSDC0_CLK__FUNC_NWEB>;
-+				drive-strength = <MTK_DRIVE_8mA>;
-+				bias-pull-up = <MTK_PUPD_SET_R1R0_10>;
-+			};
-+
-+			pins_ale {
-+				pinmux = <MT2701_PIN_116_MSDC0_CMD__FUNC_NALE>;
-+				drive-strength = <MTK_DRIVE_8mA>;
-+				bias-pull-down = <MTK_PUPD_SET_R1R0_10>;
-+			};
-+		};
-+	};
-+
-+	&nandc {
-+		status = "okay";
-+		pinctrl-names = "default";
-+		pinctrl-0 = <&nand_pins_default>;
-+		nand@0 {
-+			reg = <0>;
-+			nand-on-flash-bbt;
-+			nand-ecc-mode = "hw";
-+			nand-ecc-strength = <24>;
-+			nand-ecc-step-size = <1024>;
-+		};
-+	};
-+
-+NAND chip optional subnodes:
-+- Partitions, see Documentation/devicetree/bindings/mtd/partition.txt
-+
-+Example:
-+	nand@0 {
-+		partitions {
-+			compatible = "fixed-partitions";
-+			#address-cells = <1>;
-+			#size-cells = <1>;
-+
-+			preloader@0 {
-+				label = "pl";
-+				read-only;
-+				reg = <0x00000000 0x00400000>;
-+			};
-+			android@0x00400000 {
-+				label = "android";
-+				reg = <0x00400000 0x12c00000>;
-+			};
-+		};
-+	};
-+
-+2) ECC Engine:
-+==============
-+
-+Required BCH properties:
-+- compatible:	Should be "mediatek,mtxxxx-ecc".
-+- reg:		Base physical address and size of ECC.
-+- interrupts:	Interrupts of ECC.
-+- clocks:	ECC required clocks.
-+- clock-names:	ECC clocks internal name.
-+- status:	Disabled default. Then set "okay" by platform.
-+
-+Example:
-+
-+	bch: ecc@1100e000 {
-+		compatible = "mediatek,mt2701-ecc";
-+		reg = <0 0x1100e000 0 0x1000>;
-+		interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_LOW>;
-+		clocks = <&pericfg CLK_PERI_NFI_ECC>;
-+		clock-names = "nfiecc_clk";
-+		status = "disabled";
-+	};
