+TI ADC128D818 ADC System Monitor With Temperature Sensor
+--------------------------------------------------------
+
+Operation modes:
+
+ - Mode 0: 7 single-ended voltage readings (IN0-IN6),
+ 1 temperature reading (internal)
+ - Mode 1: 8 single-ended voltage readings (IN0-IN7),
+ no temperature
+ - Mode 2: 4 pseudo-differential voltage readings
+ (IN0-IN1, IN3-IN2, IN4-IN5, IN7-IN6),
+ 1 temperature reading (internal)
+ - Mode 3: 4 single-ended voltage readings (IN0-IN3),
+ 2 pseudo-differential voltage readings
+ (IN4-IN5, IN7-IN6),
+ 1 temperature reading (internal)
+
+If no operation mode is configured via device tree, the driver keeps the
+currently active chip operation mode (default is mode 0).
+
+
+Required node properties:
+
+ - compatible: must be set to "ti,adc128d818"
+ - reg: I2C address of the device
+
+Optional node properties:
+
+ - ti,mode: Operation mode (u8) (see above).
+
+
+Example (operation mode 2):
+
+ adc128d818@1d {
+ compatible = "ti,adc128d818";
+ reg = <0x1d>;
+ ti,mode = /bits/ 8 <2>;

+ which may cause the system instability and even damages. The IP-block

+ 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:

+features are provided, including PWM frequency control, temperature hysteresis,
+dual tachometer measurements, and fan health monitoring.
+
+Required properties:
+- compatible : One of "maxim,max31785" or "maxim,max31785a"
+- reg : I2C address, one of 0x52, 0x53, 0x54, 0x55.

+- reg : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.
+
+Optional properties, default is to retain the chip's current setting:
+- maxim,fan-microvolt : The supply voltage of the fan, either 5000000 uV or
+ 12000000 uV.
+- maxim,fan-prescale : Pre-scaling value, as per datasheet [1]. Lower values
+ allow more fine-grained control of slower fans.
+ Valid: 1, 2, 4, 8, 16.
+- maxim,fan-target-rpm: Initial requested fan rotation speed. If specified, the
+ driver selects closed-loop mode and the requested speed.
+ This ensures the fan is already running before userspace
+ takes over.
+
+Example:
+ fan-max6650: max6650@1b {

+description: |
+ The MAX20730 is a fully integrated, highly efficient switching regulator
+ with PMBus for applications operating from 4.5V to 16V and requiring
+ up to 25A (max) load. This single-chip regulator provides extremely
+ compact, high efficiency power-delivery solutions with high-precision
+ output voltages and excellent transient response.

+
+maintainers:

+
+description: |
+ A Moortec PVT (Process, Voltage, Temperature) monitoring logic design can
+ include many different units.
+ Such a design will usually consists of several Moortec's embedded analog IPs,
+ and a single Moortec controller (mr75203) to configure and control the IPs.
+
+ Some of the Moortec's analog hard IPs that can be used in a design:
+ *) Temperature Sensor (TS) - used to monitor core temperature (e.g. mr74137).
+ *) Voltage Monitor (VM) - used to monitor voltage levels (e.g. mr74138).
+ *) Process Detector (PD) - used to assess silicon speed (e.g. mr74139).
+ *) Delay Chain - ring oscillator connected to the PD, used to measure IO
+ based transistors (e.g. mr76008 ring oscillator at 1.1V, mr76007 ring
+ oscillator at 1.8V).
+ *) Pre Scaler - provides divide-by-X scaling of input voltage, which can then
+ be presented for VM for measurement within its range (e.g. mr76006 -
+ divide by 2 pre-scaler).
+
+ TS, VM & PD also include a digital interface, which consists of configuration
+ inputs and measurement outputs.
+
+ Some of the units have number of series, each series can have slightly
+ different characteristics.
+
+ The mr75203 binding describes configuration for the controller unit, but also
+ for some of the analog IPs.

+title: NTC thermistor temperature sensors

+
+description: |
+ Thermistors with negative temperature coefficient (NTC) are resistors that
+ vary in resistance in an often non-linear way in relation to temperature.
+ The negative temperature coefficient means that the resistance decreases
+ as the temperature rises. Since the relationship between resistance and
+ temperature is non-linear, software drivers most often need to use a look
+ up table and interpolation to get from resistance to temperature.
+
+ When used in practice, a thermistor is often connected between ground, a
+ pull-up resistor or/and a pull-down resistor and a fixed voltage like this:
+
+ + e.g. 5V = pull-up voltage (puv)
+ |
+ +-+
+ | |
+ | | Pull-up resistor
+ | | (puo)
+ +-+
+ |-------------------------o
+ +-+ | ^
+ | |/ |
+ | / |
+ |/| Thermistor | Measured voltage (mv)
+ / | | "connected ground"
+ /| | |
+ +-+ |
+ |-------------------------o
+ +-+ ^
+ | | |
+ | | Pull-down resistor | Measured voltage (mv)
+ | | (pdo) | "connected positive"
+ +-+ |
+ | |
+ | v
+ + GND GND
+
+ The arrangements of where we measure the voltage over the thermistor are
+ called "connected ground" and "connected positive" and shall be understood as
+ the cases when either pull-up or pull-down resistance is zero.
+
+ If the pull-up resistance is 0 one end of the thermistor is connected to the
+ positive voltage and we get the thermistor on top of a pull-down resistor
+ and we take the measure between the thermistor and the pull-down resistor.
+
+ Conversely if the pull-down resistance is zero, one end of the thermistor is
+ connected to ground and we get the thermistor under the pull-up resistor
+ and we take the measure between the pull-up resistor and the thermistor.
+
+ We can use both pull-up and pull-down resistors at the same time, and then
+ the figure illustrates where the voltage will be measured for the "connected
+ ground" and "connected positive" cases.

+Versatile Express hwmon sensors
+-------------------------------
+
+Requires node properties:
+- "compatible" value : one of
+ "arm,vexpress-volt"
+ "arm,vexpress-amp"
+ "arm,vexpress-temp"
+ "arm,vexpress-power"
+ "arm,vexpress-energy"
+- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
+ (see Documentation/devicetree/bindings/arm/vexpress-config.yaml
+ for more details)
+
+Optional node properties:
+- label : string describing the monitored value
+
+Example:
+ energy@0 {
+ compatible = "arm,vexpress-energy";
+ arm,vexpress-sysreg,func = <13 0>;
+ label = "A15 Jcore";
+ };
