pr_err("ps-hold 1 \n");
if (scm_deassert_ps_hold_supported) {
/* This call will be available on ARMv8 only */
scm_call2_atomic(SCM_SIP_FNID(SCM_SVC_PWR,
SCM_IO_DEASSERT_PS_HOLD), &desc);
}
pr_err("ps-hold address %x \n",(unsigned int)msm_ps_hold);

I don’t see problem with MangOH green board, please see attached log.
BTW, not sure if your POWER_ON_N is making the system go to power off mode.log.txt (13.8 KB)
