Please see if this one-line modification in drivers/soc/qcom/smsm.c (around line 418) in R17 can bring improvement on this issue:

static int smsm_inbound_entry(struct qcom_smsm *smsm,
			      struct smsm_entry *entry,
			      struct device_node *node)
{
	int ret;

	smsm->irq = irq_of_parse_and_map(node, 0);
	if (!smsm->irq) {
		dev_err(smsm->dev, "failed to parse smsm interrupt\n");
		return -EINVAL;
	}

	ret = devm_request_threaded_irq(smsm->dev, smsm->irq,
					NULL, smsm_intr,
					IRQF_ONESHOT,
					"smsm", (void *)entry);
	if (ret) {
		dev_err(smsm->dev, "failed to request interrupt\n");
		return ret;
	}


//Add this line for the fix
    enable_irq_wake(smsm->irq);

	entry->domain = irq_domain_add_linear(node, 32, &smsm_irq_ops, entry);
	if (!entry->domain) {
		dev_err(smsm->dev, "failed to add irq_domain\n");
		return -ENOMEM;
	}

	return 0;
}
