You can bunch these two up like this:

qupv3_se1_2uart_active: qup.... {
	tx {
		pins = ...
		foo = ...
	};

	rx {
		pins = ...
		bar = ...
	};
};

GCC and UART are parts of basic DTSI and do not make sense on their own.
Otherwise, what exactly boots on your "basic DTSI" commit if you do not
have any clocks and serial console?

Best regards,
Krzysztof

Ok Will club all the additional patches into the same base dtsi patch.
