IMX6UL ADC

Hello All,

 

I need my ADC driver working in the imx6ul board with 8 channels.

 

I have modified dtsi files as shown below:

 

            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 = <8>;

                clock-names = "adc";
                status = "disabled";
                        };

 

        pinctrl_adc1: adc1grp {

 

            fsl,pin = <
                MX6UL_PAD_GPIO1_IO07__GPIO1_IO07        0xb0
            >;

        };

 

&adc1 {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_adc1>;
    vref-supply = <&reg_mba6ul_3v3>;
    status = "okay";
};

 

But, I am able to see only in_voltage0_raw and in_voltage1_raw iio.

Could anyone please tell me what might be the mistake I am doing here?
