 *

 *  This driver fully implements the ACPI thermal policy as described in the

 *  ACPI 2.0 Specification.

 *

 *  TBD: 1. Implement passive cooling hysteresis.

 *       2. Enhance passive cooling (CPU) states/limit interface to support

 *          concepts of 'multiple limiters', upper/lower limits, etc.
