Browse source

Register ACPI thermal zone as thermal zone device.

the new sys I/F for ACPI thermal zone will be like this:

/sys/class/thermal:
|thermal_zone1:
	|-----type:			"ACPI thermal zone". RO
	|-----temp:			the current temperature. RO
	|-----mode:			the current working mode. RW.
					the default value is "kernel"  which means  thermal
					management is done by ACPI thermal driver.
					"echo user > mode" prevents all the ACPI thermal driver
					actions upon any trip points.
	|-----trip_point_0_temp:	the threshold of trip point 0. RO.
	|-----trip_point_0_type:	"critical". RO.
					the type of trip point 0
					This may be one of critical/hot/passive/active[x]
					for an ACPI thermal zone.
	...
	|-----trip_point_3_temp:
	|-----trip_point_3_type:	"active[1]"
