+SPI Master controller for Netlogic XLP MIPS64 SOCs
+==================================================
+
+Currently this SPI controller driver is supported for the following
+Netlogic XLP SoCs:
+ XLP832, XLP316, XLP208, XLP980, XLP532
+
+Required properties:
+- compatible : Should be "netlogic,xlp832-spi".
+- #address-cells : Number of cells required to define a chip select address
+ on the SPI bus.
+- #size-cells : Should be zero.
+- reg : Should contain register location and length.
+- clocks : Phandle of the spi clock
+- interrupts : Interrupt number used by this controller.
+- interrupt-parent : Phandle of the parent interrupt controller.
+
+SPI slave nodes must be children of the SPI master node and can contain
+properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.
+
+Example:
+
+ spi: xlp_spi@3a100 {
+ compatible = "netlogic,xlp832-spi";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0 0x3a100 0x100>;
+ clocks = <&spi_clk>;
+ interrupts = <34>;
+ interrupt-parent = <&pic>;
+
+ spi_nor@1 {
+ compatible = "spansion,s25sl12801";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <1>; /* Chip Select */
+ spi-max-frequency = <40000000>;
+ };
+};
