The only matches I see are in the MPTF thermal package, which ships"883ROT13Inch.bin" and "883ROT15Inch.bin". Nothing else mentions ROT. I also checked all the ACPI tables but didn't find a codename there. The tables are here: https://github.com/aarch64-laptops/build/pull/176 Following the Lenovo gen8 naming, would something like "microsoft,surface-laptop-gen8-13p8in" (mahua-microsoft-surface-laptop-gen8-13p8in.dts) work? I'm open to whatever you and Krzysztof prefer. Thanks, Gopikrishna
