Merge "esoc: Use qpnp-power-on apis to reset modem"

		management boot options. The default value is 203 milliseconds.

- qcom,esoc-skip-restart-for-mdm-crash: Boolean. If set, the esoc framework would skip the warm

		reboot phase during the momem crash.

- qcom,esoc-spmi-soft-reset: Boolean. If set, esoc framework will use qpnp apis to reset the

		external modem chip instead of toggling gpios.

Example:

	mdm0: qcom,mdm0 {

		qcom,support-shutdown;

		qcom,pil-force-shutdown;

		qcom,esoc-skip-restart-for-mdm-crash;

		qcom,esoc-spmi-soft-reset;

		pinctrl-names = "default", "mdm_active", "mdm_suspend";

		pinctrl-0 = <&ap2mdm_pon_reset_default>;

		pinctrl-1 = <&ap2mdm_active &mdm2ap_active>;
