Using other pins for resistive touchpad

Hi

I'm using an imx6ul board. In the device tree touchpad and it's pins defined like this:

&tsc {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_tsc>;
    xnur-gpio = <&gpio1 3 GPIO_ACTIVE_LOW>;
    measure-delay-time = <0xffff>;
    pre-charge-time = <0xfff>;
    status = "okay";
};
pinctrl_tsctscgrp {
   fsl,pins = <
            MX6UL_PAD_GPIO1_IO01__GPIO1_IO01        0xb0
            MX6UL_PAD_GPIO1_IO02__GPIO1_IO02        0xb0
            MX6UL_PAD_GPIO1_IO03__GPIO1_IO03        0xb0
            MX6UL_PAD_GPIO1_IO04__GPIO1_IO04        0xb0
        >;
};
 
My question is can I use other ADC pins instead this 4 pins?

Hi Majid

 

these signals are for ADC module, so one can use other ADC signals described in

Table 13-1. ADC External Signals  i.MX 6UltraLite Applications Processor Reference Manual

 

Best regards
