Okay, has anyone actually _used_ the Elo driver? I can't get the probe
function to run. I get into of_fsl_dma_init(), but of_fsl_dma_probe()
never executes. I have CONFIG_DMADEVICES and CONFIG_FSL_DMA set in my
.config, obviously since the init function runs. Here's the relevant SOC
portion of my device tree:
[EMAIL PROTECTED] {
#address-cells = <1>;
#size-cells = <1>;
#interrupt-cells = <2>;
device_type = "soc";
ranges = <0 e0000000 00100000>;
reg = <e0000000 00000200>;
bus-frequency = <0>; // from bootloader

};
};

Is there something else I need to do? Or is there something wrong with my
device tree (always a possibility :) ). Any help is appreciated.
Thanks.
