[LEDE-DEV] rt5350-spi rt2880-spi question

[Giuseppe Lippolis]

I have an update.
Using the following add to the DWR-512-B.dts

&spi1 {
        status = "okay";

        spidev at 1 {
                #address-cells = <1>;
                #size-cells = <1>;
                compatible = "spidev";
                reg = <0>;
                spi-max-frequency = <30000000>;
        };
};

I'm able to see the device:
root at lede:/tmp# ls /dev/spi*
/dev/spidev1.0

But in the bootlog I get:

I'm making something wrong?
