+NVIDIA Tegra NAND Flash controller
+
+Required properties:
+- compatible: Must be one of:
+ - "nvidia,tegra20-nand"
+- reg: MMIO address range
+- interrupts: interrupt output of the NFC controller
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - nand
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - nand
+
+Optional properties:
+- nvidia,wp-gpios: GPIO used to disable write protection of the flash
+
+ Example:
+ nand@70008000 {
+ compatible = "nvidia,tegra20-nand";
+ reg = <0x70008000 0x100>;
+ interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&tegra_car TEGRA20_CLK_NDFLASH>;
+ clock-names = "nand";
+ resets = <&tegra_car 13>;
+ reset-names = "nand";
+ };
