UART aliases are properties of the boards, not SoC.

So are you saying that we need to remove the serial aliases from files
like rk3308.dtsi, rk3328.dtsi, rk3368.dtsi, rk3399-base.dtsi,
rk356x-base.dtsi, rk3576.dtsi, rk3588-base.dtsi, and so on?

Kind regards,
XIE Zhibang

Well, I tried once but people disagreed because of impact, so probably not.

Best regards,

We had this argument a lot of times for those numbered aliases
where everything on all soc documentation, schematics and also
user documentation for individual boards, generally references
exactly those numbers :-)

But fiiiiiine, if it comes up all the time ...

I really hope, you're okay with intermitend ordering though:

	serial0 = &uart0;
	serial2 = &uart2;
	serial5 = &uart5;

because otherwise, this would cause pure chaos everywhere.

Because as I said this serial number is used on board-schematics,
board-user-level documentation, SoC documentation, even silcscreen
on boards ... so everywhere.

Similar for all the numbered busses ofthe SoCs.


Heiko
