+* Freescale Quad Serial Peripheral Interface(QuadSPI)
+
+Required properties:
+- compatible : Should be "fsl,vf610-qspi"
+- reg : Offset and length of the register set for the device
+- interrupts : Should contain the interrupt for the device
+- clocks : The clocks needed by the QuadSPI controller
+- clock-names : the name of the clocks
+- fsl,spi-num-chipselects : Contains the number of the chipselect
+
+Optional properties:
+- fsl,nor-size : If You set this property, it means that you connect the NOR
+ flash to QuadSPI. This property is mainly used by the QuadSPI
+ to map an AHB bus accessible address.
+
+Example:
+
+qspi0: quadspi@40044000 {
+ compatible = "fsl,vf610-qspi";
+ reg = <0x40044000 0x1000>;
+ interrupts = <0 24 0x04>;
+ clocks = <&clks VF610_CLK_QSPI0_EN>,
+ <&clks VF610_CLK_QSPI0>;
+ clock-names = "qspi_en", "qspi";
+ fsl,nor-size = <0x1000000>;
+ fsl,spi-num-chipselects = <1>;
+ status = "disabled";
+
+ flash0: s25fl128s@0 {
+ ....
+ };
+};
