This patch can go independently as no thermal patches depends on this.

OK, applied. Thanks!

The _ART (Active Cooling Relationship Table), specifies relationship among heat generating sources to a target active cooling device like fan. The _ART table refers to actual bus id name for specifying relationship. Naming "Fan" is not enough as name in the _ART table can change on every platform, to establish relationship for user space thermal controllers.
