+* Freescale Quad Serial Peripheral Interface(QuadSPI)
+
+Required properties:
+- compatible : Should be "fsl,vf610-qspi"
+- reg : the first contains the register location and length,
+        the second contains the memory mapping address and length
+- reg-names: Should contain the reg names "QuadSPI" and "QuadSPI-memory"
+- interrupts : Should contain the interrupt for the device
+- clocks : The clocks needed by the QuadSPI controller
+- clock-names : the name of the clocks
+
+Example:
+
+qspi0: quadspi at 40044000 {
+	compatible = "fsl,vf610-qspi";
+	reg = <0x40044000 0x1000>, <0x20000000 0x10000000>;
+	reg-names = "QuadSPI", "QuadSPI-memory";
+	interrupts = <0 24 IRQ_TYPE_LEVEL_HIGH>;
+	clocks = <&clks VF610_CLK_QSPI0_EN>,
+		<&clks VF610_CLK_QSPI0>;
+	clock-names = "qspi_en", "qspi";
+
+	flash0: s25fl128s at 0 {
