If I'm not wrong, you need to create dt-binding alias for meson-a4-uart
and use it as 3rd compatible string.
On UART module, A4 and A5 SoCs exactly the same as S4. There's no
difference.
That's not really the point. You are supposed to always provide SoC
specific compatible in front of the fallback. See writing bindings document.
Will add bindings.
If two chips use a common dtsi, and this module is in the common dtsi,
can I only add one to suit this two chips?
Best regards,
Krzysztof
