I think that's a good idea. If we go that route, I think I want to move the acpigen_write_TMP method into `struct device_operations`. This way we can cleanly support multiple temperature controllers. The ec_lpc.c code would set .acpi_write_TMP in its ops. This would all be guarded with DRIVERS_ACPI_THERMAL_ZONE so we don't increase the device tree size for everyone.
What do you think?

Also why is it part of IETM? As per the BWG doc, I don't see any scope being mentioned for ODVP package. Looking here, it is added under the scope of DPTF_PATH and not IETM. So why is it mentioned as part of ietm?
+1 to Tim's comment regarding DWORDS.
