> Thierry, do you have a patch to convert the Documentation/devicetree/bindings/serial/nvidia,tegra20-hsuart.txt to yaml? I have noticed that the above change now cause the hsuart to fail on Tegra234 ...

my patch was touching only the UART (8250), not the HSUART. These are
different compatible and different drivers. Why do you think HSUART is
affected here?
