++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>;
++ };
++ };
