pin assignment for uart0

[LongQi]

We designed our and reviewed by nordic.

I need to change the uart0 PIN assignment but our application can not receive msg from uart0 and i notice the device tree editor report something as below.

Our device tree overlay:

&uart0 {
	current-speed = <921600>;
	status = "okay";
	parity = "none";
	stop-bits = "1";
	data-bits = < 8 >;
};

/ {
	aliases {
			die-temp0 = &temp;
	};

	leds {
		led5: led5 {
			gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
			label = "LED5";
		};

		led6: led6 {
			gpios = <&gpio0 3 GPIO_ACTIVE_LOW>;
			label = "LED6";
		};
	};
};
&button0 {
	gpios = <&gpio0 10 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
};

&uart0_default {
	group1 {
		psels = <NRF_PSEL(UART_TX, 0, 11)>, <NRF_PSEL(UART_RTS, 0, 4)>;
	};

	group2 {
		psels = <NRF_PSEL(UART_RX, 0, 5)>, <NRF_PSEL(UART_CTS, 1, 9)>;
	};
};
