tca9539_77 not available in TX2 28.2 ??

Hi,
I am trying to compile the following in a dtb / dtsi,
but compiler complains that it can’t find the tca9539_77, is there a substitute in the 28.2 sources ?

have looked trough the Jetson-TX2-Generic-Customer-Pinmux-Template.xlsm and poring guide, but
cant find any info on it !!

I am a novice programmer and new to the TX2, tca9539_77 9 1 means:
tca9539_77 pin9 active high ?

/* i2c@546c0000 { // I2C_GP0, “adapter” 6 TX1 */
i2c@3180000 { // I2C_GP0, “adapter” 2 TX2 // Correct hopefully…
status = “okay”;
#address-cells = <0x1>;
#size-cells = <0x0>;
j20_2@20 {
compatible = “nvidia,j20”;
reg = <0x20>;
reset-gpios = <&tca9539_77 9 1>;
status = “okay”;
};

hello Spawn32,

  1. did you have declaration for tca9539_77 ?
  2. tca9539_77 9 1 means: tca9539_77 pin9 active high ?
    yes, but would suggest using this macro TEGRA_MAIN_GPIO() instead of ‘9’ to for better pin understanding.
