+* Atmel Quad Serial Peripheral Interface (QSPI)
+
+Required properties:
+- compatible: should be "atmel,sama5d2-qspi"
+- reg: the first contains the register location and length,
+ the second contains the memory mapping address and length
+- interrupts: should contain the interrupt for the device
+- clocks: the phandle of the clock needed by the QSPI controller
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+
+Example:
+
+spi@f0020000 {
+ compatible = "atmel,sama5d2-qspi";
+ reg = <0xf0020000 0x100>,
+ <0xd0000000 0x8000000>;
+ interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;
+ clocks = <&spi0_clk>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_spi0_default>;
+ status = "okay";
