Hi All,


I want to do an adc test on imx6ul board. But, I am not able to see anything under /sys/bus/iio/devices/.

I have enabled the ADC support in kernel configurations.

My dtsi(imx6ul.dtsi) file contains :


adc1: adc@02198000 {
compatible = "fsl,imx6ul-adc", "fsl,vf610-adc";
reg = <0x02198000 0x4000>;
interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6UL_CLK_ADC1>;
num-channels = <2>;
clock-names = "adc";
status = "disabled";


Is there anything more to be done to see the devices in /sys/bus/iio/devices/.

Could anyone kindly help me out on this ?
