[PATCH 1/2] ARM: dts: BCM5301X: Specify serial console parameters

quoted

The alias is fine. But putting the stdout-path here is unusual. Which
serial port is used for console is board specific, where as
bcm5301x.dtsi is very generic, it describes the SoC, not a board.  If
you look at other .dtsi files, those that specify stdout-path contain
properties which are common to a range of similar boards.

So far I've never seen any board using other uart. Also uart0 is disabled by
default and we enable it per board family (BCM4708 / BCM47081 / BCM4709 /
BCM47094). I think it's just more practical to have simple DTS that covers
99,9% boards by default and handled that margin of devices separately.

We already got a lot of duplicated code for enabling uart0, see:

Jon Mason from Broadcom who knows this hardware and designs very well confirmed
it's a sane/safe assumption.

I don't disagree with you, it does make sense. But it is just
different to every other SoC .dtsi file Linux has. And we try to avoid
things being different.

It is down to Florian to decide, as maintainer.
