+* Atmel Quad Serial Peripheral Interface (QSPI)
+
+Required properties:
+- compatible: Should be "atmel,sama5d2-qspi".
+- reg: Should contain the locations and lengths of the base registers
+ and the mapped memory.
+- reg-names: Should contain the resource reg names:
+ - qspi_base: configuration register address space
+ - qspi_mmap: memory mapped address space
+- 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@...20000 {
+ compatible = "atmel,sama5d2-qspi";
+ reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>;
+ reg-names = "qspi_base", "qspi_mmap";
+ 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";
