What about platform support? I see that there is a patch in your git tree at https://git.linaro.org/leg/acpi/acpi.git/commitdiff/b9a635e3b4cb167d399 that exposes the raw system registers in the same way that the DT support does, which I guess is not how you plan to do it for ACPI when you are done. Is that still work in progress? How do you plan to abstract things like the hwmon, LEDs, GPIO etc that are handled through the sysregs in hardware? Arnd
