There is no problem with swnodes, except missing parts (*). I have Skylake laptop with IPU3 and with half-baked ACPI tables, but since we have drivers in place with fwnode support, we only need to recreate fwnode graph in some board file to compensate the gap in ACPI. *) Missing part is graph support for swnodes. With that done it will be feasible to achieve the rest. I forgot if we have anything for this already done. Heikki? -- With Best Regards, Andy Shevchenko
