We have many more changes like this in OpenWrt, I just didn't upstream
them because of current chipcommonA state.

It was added before we got "brcm,bus-axi" and I believe Hauke wanted
move it to the "correct" place at some point. Since UART is part of
ChipCommon device and ChipCommon is part of "brcm,bus-axi",.I guess we
should add UARTs as a ChipCommon device subnodes. We already have
chipcommon: chipcommon at 0 {
        reg = <0x00000000 0x1000>;

        gpio-controller;
        #gpio-cells = <2>;
};
, is it possible to move UARTs there?

I'm not sure if this UART cleanup should block your change. I guess it
depends on the way it'll finally look like.

I do not think it will, see below:

You answered about using &uart0 instead a whole path and it sounds OK.

What about moving this whole chipcommonA node into "chipcommon: chipcommon at 0"?
Hauke did you try that?
