Hi Nvidia,

We upgrade BSP from 35.2.1 to 35.4.1
patch these files into 35.4.1 on customer carrier board.

patch from : HDMI Display does not work after update to JetPack 5.0.2 - #27 by WayneWWW

after flash image into module , kernel will dump and hang , then reboot again due to wdt timeout

when we mask os_gpio_hotplug_a , kernel will not hang anymore,
display@13800000 {
status = “okay”;
//os_gpio_hotplug_a = <&tegra_main_gpio TEGRA234_MAIN_GPIO(M, 0) GPIO_ACTIVE_HIGH>;
};

but , without this property (os_gpio_hotplug_a) , hdmi will no hot-plug function. so we can not change panel run time. and also have to have a hdmi panel insert at boot time.

Do nvidia guys any idea ?
