- +Ralink SoC RT2880 SPI master controller.
- +
- +This SPI controller is found on most wireless SoCs made by ralink.
- +
- +Required properties:
- +- compatible : "ralink,rt2880-spi"
- +- reg : The register base for the controller.
- +- #address-cells : <1>, as required by generic SPI binding.
- +- #size-cells : <0>, also as required by generic SPI binding.
- +
- +Child nodes as per the generic SPI binding.
- +
- +Example:
- +
- + spi@b00 {
- + compatible = "ralink,rt2880-spi";
- + reg = <0xb00 0x100>;
- +
- + #address-cells = <1>;
- + #size-cells = <0>;
- +
- + m25p80@0 {
- + compatible = "m25p80";
- + reg = <0>;
- + spi-max-frequency = <10000000>;
- + };
- + };
