17 +Ralink SoC RT2880 SPI master controller.
18 +
19 +This SPI controller is found on most wireless SoCs made by ralink.
20 +
21 +Required properties:
22 +- compatible : "ralink,rt2880-spi"
23 +- reg : The register base for the controller.
24 +- #address-cells : <1>, as required by generic SPI binding.
25 +- #size-cells : <0>, also as required by generic SPI binding.
26 +
27 +Child nodes as per the generic SPI binding.
28 +
29 +Example:
30 +
31 + spi@b00 {
32 + compatible = "ralink,rt2880-spi";
33 + reg = <0xb00 0x100>;
34 +
35 + #address-cells = <1>;
36 + #size-cells = <0>;
37 +
38 + m25p80@0 {
39 + compatible = "m25p80";
40 + reg = <0>;
41 + spi-max-frequency = <10000000>;
42 + };
43 + };
