DPTF Processor thermal RFIM interface
--------------------------------------------
-RFIM interface allows adjustment of FIVR (Fully Integrated Voltage Regulator)
-and DDR (Double Data Rate)frequencies to avoid RF interference with WiFi and 5G.
+RFIM interface allows adjustment of FIVR (Fully Integrated Voltage Regulator),
+DDR (Double Data Rate) and DLVR (Digital Linear Voltage Regulator)
+frequencies to avoid RF interference with WiFi and 5G.
Switching voltage regulators (VR) generate radiated EMI or RFI at the
fundamental frequency and its harmonics. Some harmonics may interfere
radio channels. OEM or ODMs can use the driver to control SOC IVR
operation within the range where it does not impact IVR performance.
+Some products use DLVR instead of FIVR as switching voltage regulator.
+In this case attributes of DLVR must be adjusted instead of FIVR.
+
+While shifting the frequencies additional clock noise can be introduced,
+which is compensated by adjusting Spread spectrum percent. This helps
+to reduce the clock noise to meet regulatory compliance. This spreading
+% increases bandwidth of signal transmission and hence reduces the
+effects of interference, noise and signal fading.
+
DRAM devices of DDR IO interface and their power plane can generate EMI
at the data rates. Similar to IVR control mechanism, Intel offers a
mechanism by which DDR data rates can be changed if several conditions

1.4 Thermal Zone Parameters
---------------------------
- ::
-
- struct thermal_bind_params
-
- This structure defines the following parameters that are used to bind
- a zone with a cooling device for a particular trip point.
-
- .cdev:
- The cooling device pointer
- .weight:
- The 'influence' of a particular cooling device on this
- zone. This is relative to the rest of the cooling
- devices. For example, if all cooling devices have a
- weight of 1, then they all contribute the same. You can
- use percentages if you want, but it's not mandatory. A
- weight of 0 means that this cooling device doesn't
- contribute to the cooling of this zone unless all cooling
- devices have a weight of 0. If all weights are 0, then
- they all contribute the same.
- .trip_mask:
- This is a bit mask that gives the binding relation between
- this thermal zone and cdev, for a particular trip point.
- If nth bit is set, then the cdev and thermal zone are bound
- for trip point n.
- .binding_limits:
- This is an array of cooling state limits. Must have
- exactly 2 * thermal_zone.number_of_trip_points. It is an
- array consisting of tuples <lower-state upper-state> of
- state limits. Each trip will be associated with one state
- limit tuple when binding. A NULL pointer means
- <THERMAL_NO_LIMITS THERMAL_NO_LIMITS> on all trips.
- These limits are used when binding a cdev to a trip point.
- .match:
- This call back returns success(0) if the 'tz and cdev' need to
- be bound, as per platform data.
-
::
struct thermal_zone_params
will be created. when no_hwmon == true, nothing will be done.
In case the thermal_zone_params is NULL, the hwmon interface
will be created (for backward compatibility).
- .num_tbps:
- Number of thermal_bind_params entries for this zone
- .tbp:
- thermal_bind_params entries
