I have an update.
Using the following add to the DWR-512-B.dts
&spi1 {
status = "okay";
spidev@1 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "spidev";
reg = <0>;
spi-max-frequency = <30000000>;
};
};
I'm able to see the device:
root@lede:/tmp# ls /dev/spi*
/dev/spidev1.0
But in the bootlog I get:
