41 This is becoming a common feature for Intel SoCs to expose the additional
42 digital temperature sensors (DTSs) using side band interface (IOSF). This
43 implements the common set of helper functions to register, get temperature
44 and get/set thresholds on DTSs.

52 Enable this to register Intel SoCs (e.g. Bay Trail) platform digital
53 temperature sensor (DTS). These SoCs have two additional DTSs in
54 addition to DTSs on CPU cores. Each DTS will be registered as a
55 thermal zone. There are two trip points. One of the trip point can
56 be set by user mode programs to get notifications via Linux thermal
57 notification methods.The other trip is a critical trip point, which
58 was set by the driver based on the TJ MAX temperature.

64 Enable this to register Intel Quark SoC (e.g. X1000) platform digital
65 temperature sensor (DTS). For X1000 SoC, it has one on-die DTS.
66 The DTS will be registered as a thermal zone. There are two trip points:
67 hot & critical. The critical trip point default value is set by
68 underlying BIOS/Firmware.

100 activation temperature via the TCC Offset register, which is widely
101 supported on modern Intel platforms.
102 Note that, on different platforms, the behavior might be different
103 on how fast the setting takes effect, and how much the CPU frequency
104 is reduced.

113 Select this option to enable the Hardware Feedback Interface. If
114 selected, hardware provides guidance to the operating system on
115 the performance and energy efficiency capabilities of each CPU.
116 These capabilities may change as a result of changes in the operating
117 conditions of the system such power and thermal limits. If selected,
118 the kernel relays updates in CPUs' capabilities to userspace.
