[35.4.1] Orin Nano cannot suspend on Xavier NX devkit

[fengying_chu]

Hi,
I used 35.4.1 on Orin Nano 4gb with Xavier NX board and I found that it cannot suspend.
The DUT will be reboot after the command: sudo systemctl suspend.

Could you please check this issue? Thank you a lot.

The command I used to build:
sudo BOARDID=3767 BOARDSKU=0004 ./tools/kernel_flash/l4t_initrd_flash.sh --massflash 10 --no-flash --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal

The file I modified in order to build, flash, boot up successfully: tegra234-mb2-bct-scr-p3767-0000.dts

The console log shows the following information:

Could you try to apply this patch to your ./bootloader/t186ref/BCT/tegra234-mb2-bct-scr-p3767-0000.dts ?

reg@322 { /* GPIO_CTL, GPIO_M_SCR_00_0 */
            exclusion-info = <2>;
            value = <0x38009696>;
        };

Hi @WayneWWW ,
I have your patch and run suspend-resume test. About 114 times, the device just reboot, instead of suspend.
使用您的patch，效果有好。但是，我們在測試suspend-resume test時，約莫114次發生重新開機的現象，並沒有suspend下去。

看起來跟原本的問題已經無關了 麻煩開一個新的topic然後幫我在devkit複製.
