RE: NRF9160 DK using P0.14 pin as Output

I have managed to get P0.14 working as Ouput.

Below are the hacks.

Flash "hello_world" sample in NRF52840 with below nrf9160dk_nrf52840.overlay

vcom2_pins_routing: switch-nrf91-uart2 {
		compatible = "nordic,nrf9160dk-optional-routing";
		/*
		 * Two pins (P1.12 and P0.12) need to be driven for
		 * this switch.
		 */
		control-gpios = <&gpio1 0 GPIO_ACTIVE_HIGH>,
				<&gpio0 0 GPIO_ACTIVE_HIGH>;
		status = "okay";
	};

gpio1 0 & gpio0 0 can be any unused PIns you can think of for NRF52840

And use your main code for NRF9160 with nrf9160dk_nrf9160ns.overlay

&uart1 {
	status = "okay";
	current-speed = <115200>;
	tx-pin = <1>;
	rx-pin = <0>;
	rts-pin = <32>;
	cts-pin = <15>;
};

P0.32 can be any unused Pin.

After getting above things right, I am able to toggle P0.14 Pin for my RESET control.
