ad9361 + no-os + linux devicetree?

My apologies if the answer to this is readily available on the web, but I couldn't manage to find anything.


Would anyone be able to point me at a device tree entry that i could use for using the no-os ad9361 driver code under linux? I'm specifically looking for the device tree entry that will create the "/dev/spidev32766.0" device. I have put something together myself based on tidbits i gathered around the web, but i'm getting a "failed to transfer one message from queue" error with 'my' spidev device. The no-os driver works fine on my zedboard+fmcomms2 setup when running bare metal, so it appears that i have something messed up in my linux-based spi driver or its configuration.


For bonus points, is there a uio device tree entry to support the uio device the no-os linux driver is attempting to open for the adc and dac dma's?
