-description: |
-  Baikal-T1 SoC provides an embedded process, voltage and temperature
-  sensor to monitor an internal SoC environment (chip temperature, supply
-  voltage and process monitor) and on time detect critical situations,
-  which may cause the system instability and even damages. The IP-block
-  is based on the Analog Bits PVT sensor, but is equipped with a dedicated
-  control wrapper, which provides a MMIO registers-based access to the
-  sensor core functionality (APB3-bus based) and exposes an additional
-  functions like thresholds/data ready interrupts, its status and masks,
-  measurements timeout. Its internal structure is depicted on the next
-  diagram:

-Each fan subnode must have one PWM channel and at least one Fan tach channel.
-
-For PWM channel can be configured cooling-levels to create cooling device.
-Cooling device could be bound to a thermal zone for the thermal control.
-
-Required properties for each child node:
-- reg : specify the PWM output channel.
-	integer value in the range 0 through 7, that represent
-	the PWM channel number that used.
-
-- fan-tach-ch : specify the Fan tach input channel.
-		integer value in the range 0 through 15, that represent

+
+This driver implements support for the PMBus monitor on the Sony APS-379
+modular power supply. The APS-379 deviates from the PMBus standard for the
+READ_VOUT command by using the linear11 format instead of linear16.

-Description
------------
-
-This driver implements support for the hardware monitoring capabilities of the
-embedded into Baikal-T1 process, voltage and temperature sensors. PVT IP-core
-consists of one temperature and four voltage sensors, which can be used to
-monitor the chip internal environment like heating, supply voltage and
-transistors performance. The driver can optionally provide the hwmon alarms
-for each sensor the PVT controller supports. The alarms functionality is made
-compile-time configurable due to the hardware interface implementation
-peculiarity, which is connected with an ability to convert data from only one
-sensor at a time. Additional limitation is that the controller performs the
-thresholds checking synchronously with the data conversion procedure. Due to
-these in order to have the hwmon alarms automatically detected the driver code
-must switch from one sensor to another, read converted data and manually check
-the threshold status bits. Depending on the measurements timeout settings
-(update_interval sysfs node value) this design may cause additional burden on
-the system performance. So in case if alarms are unnecessary in your system
-design it's recommended to have them disabled to prevent the PVT IRQs being
-periodically raised to get the data cache/alarms status up to date. By default
-in alarm-less configuration the data conversion is performed by the driver
-on demand when read operation is requested via corresponding _input-file.
-
-Temperature Monitoring
-----------------------
-
-Temperature is measured with 10-bit resolution and reported in millidegree
-Celsius. The driver performs all the scaling by itself therefore reports true
-temperatures that don't need any user-space adjustments. While the data
-translation formulae isn't linear, which gives us non-linear discreteness,
-it's close to one, but giving a bit better accuracy for higher temperatures.
-The temperature input is mapped as follows (the last column indicates the input
-ranges)::
-
-	temp1: CPU embedded diode	-48.38C - +147.438C
-
-In case if the alarms kernel config is enabled in the driver the temperature input
-has associated min and max limits which trigger an alarm when crossed.
-
-Voltage Monitoring
-------------------
-
-The voltage inputs are also sampled with 10-bit resolution and reported in
-millivolts. But in this case the data translation formulae is linear, which
-provides a constant measurements discreteness. The data scaling is also
-performed by the driver, so returning true millivolts. The voltage inputs are
-mapped as follows (the last column indicates the input ranges)::
-
-	in0: VDD		(processor core)		0.62V - 1.168V
-	in1: Low-Vt		(low voltage threshold)		0.62V - 1.168V
-	in2: High-Vt		(high voltage threshold)	0.62V - 1.168V
-	in3: Standard-Vt	(standard voltage threshold)	0.62V - 1.168V
-
-In case if the alarms config is enabled in the driver the voltage inputs
-have associated min and max limits which trigger an alarm when crossed.

+Description
+-----------
+
+This driver provides hardware monitoring for the LattePanda Sigma
+single-board computer made by DFRobot. The board uses an ITE IT8613E
+Embedded Controller to manage a CPU cooling fan and thermal sensors.
+
+The BIOS declares the ACPI Embedded Controller (``PNP0C09``) with
+``_STA`` returning 0, preventing the kernel's ACPI EC subsystem from
+initializing. This driver reads the EC directly via the standard ACPI
+EC I/O ports (``0x62`` data, ``0x66`` command/status).

+Description
+-----------
+
+This driver implements support for the MCP998X family containing: MCP9982,
+MCP9982D, MCP9983, MCP9983D, MCP9984, MCP9984D, MCP9985, MCP9985D,
+MCP9933 and MCP9933D.
+
+The MCP998X Family is a high accuracy 2-wire multichannel automotive
+temperature monitor.
+
+The chips in the family have different numbers of external channels,
+ranging from 1 (MCP9982) to 4 channels (MCP9985). Reading diodes in
+anti-parallel connection is supported by MCP9984/85/33 and
+MCP9984D/85D/33D. Dedicated hardware shutdown circuitry is present
+only in MCP998XD and MCP9933D.
+
+Temperatures are read in millidegrees Celsius, ranging from -64 to
+191.875 with 0.125 precision.
+
+Each channel has a minimum, maximum, and critical limit alongside associated alarms.
+The chips also implement a hysteresis mechanism which applies only to the maximum
+and critical limits. The relative difference between a limit and its hysteresis
+is the same for both and the value is kept in a single register.
+
+The chips measure temperatures with a variable conversion rate.
+Update_interval = Conversion/Second, so the available options are:
+- 16000 (ms) = 1 conv/16 sec
+- 8000 (ms) = 1 conv/8 sec
+- 4000 (ms) = 1 conv/4 sec
+- 2000 (ms) = 1 conv/2 sec
+- 1000 (ms) = 1 conv/sec
+- 500 (ms) = 2 conv/sec
+- 250 (ms) = 4 conv/sec
+- 125 (ms) = 8 conv/sec
+- 64 (ms) = 16 conv/sec
+- 32 (ms) = 32 conv/sec
+- 16 (ms) = 64 conv/sec
+
+Usage Notes
+-----------
+
+Parameters that can be configured in devicetree:
+- anti-parallel diode mode operation
+- resistance error correction on channels 1 and 2
+- resistance error correction on channels 3 and 4
+- power state
+
+Chips 82/83 and 82D/83D do not support anti-parallel diode mode.
+For chips with "D" in the name resistance error correction must be on.
+Please see Documentation/devicetree/bindings/hwmon/microchip,mcp9982.yaml
+for details.
+
+There are two power states:
+- Active state: in which the chip is converting on all channels at the
+programmed rate.
+
+- Standby state: in which the host must initiate a conversion cycle.
+
+Chips with "D" in the name work in Active state only and those without
+can work in either state.
+
+Chips with "D" in the name can't set update interval slower than 1 second.
+
+Among the hysteresis attributes, only the tempX_crit_hyst ones are writeable
+while the others are read only. Setting tempX_crit_hyst writes the difference
+between tempX_crit and tempX_crit_hyst in the hysteresis register. The new value
+applies automatically  to the other limits. At power up the device starts with
+a 10 degree hysteresis.
+
+Sysfs entries
+-------------
+
+The following attributes are supported. The temperature limits and
+update_interval are read-write. The attribute tempX_crit_hyst is read-write,
+while tempX_max_hyst is read only. All other attributes are read only.
+
+======================= ==================================================

+Description
+-----------
+
+This driver provides fan speed monitoring for modern Lenovo consumer laptops.
+Most Lenovo laptops do not provide fan tachometer data through standard
+ISA/LPC hardware monitoring chips. Instead, the data is stored in the
+Embedded Controller (EC) and exposed via ACPI.
+
+The driver implements a **Rate-Limited Lag (RLLag)** filter to handle
+the low-resolution and jittery sampling found in Lenovo EC firmware.
+
+Hardware Identification and Multiplier Logic
+--------------------------------------------
+
+The driver supports two distinct EC architectures. Differentiation is handled
+deterministically via a DMI Product Family quirk table during the probe phase,
+eliminating the need for runtime heuristics.
+
+1. 8-bit EC Architecture (Multiplier: 100)
+
+   - **Families:** Yoga, IdeaPad, Slim, Flex.
+   - **Technical Detail:** These models allocate a single 8-bit register for
+     tachometer data. Since 8-bit fields are limited to a value of 255, the
+     BIOS stores fan speed in units of 100 RPM (e.g., 42 = 4200 RPM).
+
+2. 16-bit EC Architecture (Multiplier: 1)
+
+   - **Families:** Legion, LOQ.
+   - **Technical Detail:** High-performance gaming models require greater
+     precision for fans exceeding 6000 RPM. These use a 16-bit word (2 bytes)
+     storing the raw RPM value directly.
+
+Filter Details
+--------------
+
+The RLLag filter is a passive discrete-time first-order lag model that ensures:
+  - **Smoothing:** Low-resolution step increments are smoothed into 1-RPM increments.
+  - **Slew-Rate Limiting:** Prevents unrealistic readings by capping the change
+    to 1500 RPM/s, matching physical fan inertia.
+  - **Polling Independence:** The filter math scales based on the time delta
+    between userspace reads, ensuring a consistent physical curve regardless
+    of polling frequency.
+
+Suspend and Resume
+------------------
+
+The driver utilizes the boottime clock (ktime_get_boottime()) to calculate the
+sampling delta. This ensures that time spent in system suspend is accounted
+for. If the delta exceeds 5 seconds (e.g., after waking the laptop), the
+filter automatically resets to the current hardware value to prevent
+reporting "ghost" RPM data from before the sleep state.
+
+Usage
+-----
+
+The driver exposes standard hwmon sysfs attributes:
+
+===============   ============================
+Attribute         Description
+fanX_input        Filtered fan speed in RPM.
+===============   ============================
+
+
+Note: If the hardware reports 0 RPM, the filter is bypassed and 0 is reported
+immediately to ensure the user knows the fan has stopped.
