1	* Atmel Quad Serial Peripheral Interface (QSPI)
2	
3	Required properties:
4	- compatible:     Should be "atmel,sama5d2-qspi".
5	- reg:            Should contain the locations and lengths of the base registers
6	                  and the mapped memory.
7	- reg-names:      Should contain the resource reg names:
8	                  - qspi_base: configuration register address space
9	                  - qspi_mmap: memory mapped address space
10	- interrupts:     Should contain the interrupt for the device.
11	- clocks:         The phandle of the clock needed by the QSPI controller.
12	- #address-cells: Should be <1>.
13	- #size-cells:    Should be <0>.
14	
15	Example:
16	
17	spi@f0020000 {
18		compatible = "atmel,sama5d2-qspi";
19		reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>;
20		reg-names = "qspi_base", "qspi_mmap";
21		interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;
22		clocks = <&spi0_clk>;
23		#address-cells = <1>;
24		#size-cells = <0>;
25		pinctrl-names = "default";
26		pinctrl-0 = <&pinctrl_spi0_default>;
27	
28		m25p80@0 {
29			...
30		};
31	};
