    SPI-NAND drivers changes:
     - Toshiba:
        * Add support for all Toshiba products.
     - Macronix:
        * Fix ECC status read.
     - Gigadevice:

+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"
+- 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" - device clock from eMMC sub clock controller
+	"rx" - rx clock phase
+	"tx" - tx clock phase
+
+- amlogic,mmc-syscon	: Required for NAND clocks, it's shared with SD/eMMC
+				controller port C
+
+Optional children nodes:
+Children nodes represent the available nand chips.
+
+Other properties:
+see Documentation/devicetree/bindings/mtd/nand.txt for generic bindings.
+
+Example demonstrate on AXG SoC:
+
+	sd_emmc_c_clkc: mmc@7000 {
+		compatible = "amlogic,meson-axg-mmc-clkc", "syscon";
+		reg = <0x0 0x7000 0x0 0x800>;
+	};
+
+	nand-controller@7800 {
+		compatible = "amlogic,meson-axg-nfc";
+		reg = <0x0 0x7800 0x0 0x100>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		interrupts = <GIC_SPI 34 IRQ_TYPE_EDGE_RISING>;
+
+		clocks = <&clkc CLKID_SD_EMMC_C>,
+			<&sd_emmc_c_clkc CLKID_MMC_DIV>,
+			<&sd_emmc_c_clkc CLKID_MMC_PHASE_RX>,
+			<&sd_emmc_c_clkc CLKID_MMC_PHASE_TX>;
+		clock-names = "core", "device", "rx", "tx";
+		amlogic,mmc-syscon = <&sd_emmc_c_clkc>;
+
+		pinctrl-names = "default";
+		pinctrl-0 = <&nand_pins>;
+
+		nand@0 {
+			reg = <0>;
+			#address-cells = <1>;
