with “manual” supply of a high level to the EN input of the video sensor module IMX219, the driver works fine and the sensor is available in the system, also the Argus-Camera connects without any problems and broadcasts the image from the sensor.
But at the same time, CAM0_RST_L TEGRA234_MAIN_GPIO(H, 3) is not controlled from the driver.
may I know which JetPack release you’re working with?
I saw some issues while using GPIO marco, could you please try using GPIO number directly,
you may using $ sudo cat /sys/kernel/debug/gpio | grep PH.03 to check the GPIO number.
I did see some issues related to GPIO marco on JP-5.0.2,
you may either upgrade to later Jetpack release version, or trying below to control the pin, i.e. pwdn-gpios = <&tegra_main_gpio 394 GPIO_ACTIVE_HIGH>;
