Change pin pullup state in Pinmux without configs

Hello! I want to change one pin to input pull none configuration.

On Linux for Jetson docs it says that I have to run some Python script from Jetson or something - is it possible to do it simply via the main .dts file (tegra186-p3636-0001-p3509-0000-a01.dts)?

I tried adding this to the end of my main .dts file, but it doesn’t work

pinmux@2430000 {
        pinmux_default: common {
            ts_int_active: ts-int-active {
                nvidia,pins = "gpio_cam2_pn1";
                nvidia,pull = <TEGRA_PIN_PULL_NONE>;
                nvidia,tristate = <TEGRA_PIN_DISABLE>;
                nvidia,enable-input = <TEGRA_PIN_ENABLE>;
                status = "okay";
            };
        };
    };

I don’t want to generate Excel stuff or anything - I want the simplest way to redefine one single pin.

hello therealmatiss,

it’s *.cfg file flashed to the target to write the pin configurations.
you’ll need to perform the python script, pinmux-dts2cfg.py to convert those pinmux *.dist files into *.cfg format.
please refer to developer guide, Pinmux Changes, for the steps to customize the pinmux spreadsheet.
thanks

Oh, thanks! I only noticed Excel dtsi generator and not the cfg
