Hi Nvidia,

Set system to suspend will cause device reboot on BSP 35.4.1 with HDMI design.
$ sudo systemctl suspend

We found this may be caused by HDMI hpd .

Here is our testing result :
(a)System Suspend successfully
Module : 0004 (production module)
Carrier : customer board (display = HDMI )
Image : pure nvidia release image (default display : DP)
Linux_for_Tegra modify :
set cvb_eeprom_read_size = <0x0>;

(b)System Suspend will reboot
Module : 0004 (production module)
Carrier : customer board (display = HDMI )
Image : default nvidia release image + dtb update with HDMI dcb used and os_gpio_hotplug_a include.
Linux_for_Tegra modify :

set cvb_eeprom_read_size = <0x0>;

;
pinmux :
dp_aux_ch0_hdp_pm0 {
nvidia,function = “rsvd1”;
};

gpio :  gpio-input = < 
          TEGRA234_MAIN_GPIO(M, 0)

;
scr : reg@322 { /* GPIO_M_SCR_00_0 */
exclusion-info = <2>;
value = <0x38008080>;
};

Only change display from DP to HDMI , then, set system to suspend will trigger device reboot.
