The Google Tensor G5 SoC (known as "laguna" and canonically written in
code as "lga") has a UART based on Designware IP. The UART appears to
work reasonably well, at least for serial console, with the existing
driver in Linux. Add a compatible for this UART based on the canonical
"lga" name for this SoC with a fallback to the existing
"snps,dw-apb-uart".
