Description:

		The file exposes "Extended Test Mode Register 3" global

		reset bits. The bits are used during an Intel platform

		manufacturing process to indicate that consequent reset

		of the platform is a "global reset". This type of reset

		is required in order for manufacturing configurations

		to take effect.



		Display global reset setting bits for PMC.

			* bit 31 - global reset is locked

			* bit 20 - global reset is set

		Writing bit 20 value to the etr3 will induce

		a platform "global reset" upon consequent platform reset,

		in case the register is not locked.

		The "global reset bit" should be locked on a production

		system and the file is in read-only mode.

WWAN Antenna type

-----------------



sysfs: wwan_antenna_type



On some newer Thinkpads we need to set SAR value based on the antenna

type. This interface will be used by userspace to get the antenna type

and set the corresponding SAR value, as is required for FCC certification.



The available commands are::



        cat /sys/devices/platform/thinkpad_acpi/wwan_antenna_type



Currently 2 antenna types are supported as mentioned below:

- type a

- type b



The property is read-only. If the platform doesn't have support the sysfs

class is not created.
