-Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
-
-Provide support for adding configurable high and
-configurable low trip temperatures. An interrupts is
-also triggerred when these trip points are hit. The
-interrupts can be activated or deactivated from sysfs.
-This functionality is made available only if
-CONFIG_THERMAL_WRITABLE_TRIPS is defined.
