As an aside, this is perfectly OK, but I wonder why you chose to use
compatible=nvidia,tegra124-hsuart rather than
compatible=nvidia,tegra124-uart. The -hsuart driver has had less testing
upstream, whereas the regular -uart driver is heavily used for the main
serial console. I assume you tested the new driver when enabling the
ports:-)
