+* 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@f0020000 {

Once again, the ePAPR standard tells up to call the node just "spi", not "qspi".

+	compatible = "atmel,sama5d2-qspi";
+	reg = <0xf0020000 0x100>,
+	      <0xd0000000 0x08000000>;

   Either you use the leading zeroes or you don't. :-)
