-+ * repeat this process on a resume from Sx. BIOS may enable any or all of
-+ * the registers below based on OEM's platform configuration. Intel does

-+ * different temperature trip points and one may enable a trip to cause an
-+ * SMI while another platform would cause an interrupt instead.
-+ *
-+ * The recommended flow for enabling thermal sensor is by setting up various
-+ * temperature trip points first, followed by enabling the desired trip
-+ * alert method and then enable the actual sensors from TSEL registers.
-+ * If this flow is not followed, software will need to take special care
-+ * to handle false events during setting up those registers.
