Official Documentation say "Surface Laptop, 13.8 inch (8th Edition)" We have to create a dedicated board file for the fifteen inch variant since it is expected to have a sd-card port and another one for 13inch specifically to enable ufs. All of them will have only lcd panels. So how about if we go with the following? microsoft,surface-laptop-8-lcd13 microsoft,surface-laptop-8-lcd13p8 microsoft,surface-laptop-8-lcd15 With this is mind it might make sense to create a common file mahua-microsoft-surface-laptop-8.dtsi that all these boards can import from as well. -Sibi > > Konrad
