[beagleboard] Reading ADC, get "cat: in_voltage0_raw: Device or resource busy"

[Rick Mann]

What am I missing here?

# uname -r
3.8.13-bone72

# pwd
/sys/bus/iio/devices/iio:device0

# ls
dev  in_voltage0_raw  in_voltage1_raw  in_voltage2_raw  name  power/  
subsystem@  uevent

# cat in_voltage0_raw 
cat: in_voltage0_raw: Device or resource busy

The fragment from my DTBO:

        fragment@6 {
                target = <&tscadc>;
                __overlay__ {

                        status = "okay";
                        adc {
                                ti,adc-channels = <0 1 2>;
                        };
                };
        };

Thanks,
