-Subject: [PATCH] platform/x86: thinkpad_acpi: lap or desk mode interface
-
-Newer Lenovo Thinkpad platforms have support to identify whether the
-system is on-lap or not using an ACPI DYTC event from the firmware.
-
-This patch provides the ability to retrieve the current mode via sysfs
-entrypoints and will be used by userspace for thermal mode and WWAN
-functionality

-+DYTC Lapmode sensor
-+------------------
-+
-+sysfs: dytc_lapmode
-+
-+Newer thinkpads and mobile workstations have the ability to determine if
-+the device is in deskmode or lapmode. This feature is used by user space
-+to decide if WWAN transmission can be increased to maximum power and is
-+also useful for understanding the different thermal modes available as
-+they differ between desk and lap mode.
-+
-+The property is read-only. If the platform doesn't have support the sysfs
-+class is not created.

- EXPERIMENTAL: UWB
