   1 SPI Master controller for Netlogic XLP MIPS64 SOCs
   2 ==================================================
   3
   4 Currently this SPI controller driver is supported for the following
   5 Netlogic XLP SoCs:
   6         XLP832, XLP316, XLP208, XLP980, XLP532
   7
   8 Required properties:
   9 - compatible            : Should be "netlogic,xlp832-spi".
  10 - #address-cells        : Number of cells required to define a chip select address
  11                           on the SPI bus.
  12 - #size-cells           : Should be zero.
  13 - reg                   : Should contain register location and length.
  14 - clocks                : Phandle of the spi clock
  15 - interrupts            : Interrupt number used by this controller.
  16 - interrupt-parent      : Phandle of the parent interrupt controller.
  17
  18 SPI slave nodes must be children of the SPI master node and can contain
  19 properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.

  21 Example:
  22
  23         spi: xlp_spi@3a100 {
  24                 compatible = "netlogic,xlp832-spi";
  25                 #address-cells = <1>;
  26                 #size-cells = <0>;
  27                 reg = <0 0x3a100 0x100>;
  28                 clocks = <&spi_clk>;
  29                 interrupts = <34>;
  30                 interrupt-parent = <&pic>;
  31
  32                 spi_nor@1 {
  33                         compatible = "spansion,s25sl12801";
  34                         #address-cells = <1>;
  35                         #size-cells = <1>;
  36                         reg = <1>;      /* Chip Select */
  37                         spi-max-frequency = <40000000>;
  38                 };
  39 };
