From 5c36cf27846a364f830e5ea86b411e05f7c8bd2b Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Mon, 23 Jan 2023 08:30:46 -0800 Subject: thermal: intel: int340x: Add production mode attribute It is possible that the system manufacturer locks down thermal tuning beyond what is usually done on the given platform. In that case user space calibration tools should not try to adjust the thermal configuration of the system. To allow user space to check if that is the case, add a new sysfs attribute "production_mode" that will be present when the ACPI DCFG method is present under the INT3400 device object in the ACPI Namespace.
