Can not control GPIO on Jetson Orin Nano

Hi ZXZhang,

It is not the expected operation to me.

gpio.dtsi has been inlcuded in pinmux.dtsi so it does not need to be specified in board config.
GPIOINT_CONFIG is used for gpio-interrupt configuration.

Do you modify any line relating to bpmp-dtb?

To control GPIO with Jetpack 6.x, please also apply the patch from the following thread.
40hdr - SPI1 gpio padctl register bit[10] effect by gpiod tools in JP6 - #20 by KevinFFF
Or you can use Jetpack 6.2.2(r36.5) which should include that patch.
