+* 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 clock needed by the QSPI controller
+ - #address-cells : should be 1
+ - #size-cells : should be 0
+
+Example:
+
+qspi0: qspi at f0020000 {
+ compatible = "atmel,sama5d2-qspi";
+ reg = <0xf0020000 0x100>,
+ <0xd0000000 0x08000000>;
+ interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;
+ clocks = <&qspi0_clk>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_qspi0_default>;
+ status = "okay";
