+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>;

+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:

+Nuvoton NPCM7xx PWM and Fan Tacho controller device
+
+The Nuvoton BMC NPCM7XX supports 8 Pulse-width modulation (PWM)
+controller outputs and 16 Fan tachometer controller inputs.
+
+Required properties for pwm-fan node

+- #size-cells	: should be 0.
+- compatible	: "nuvoton,npcm750-pwm-fan" for Poleg NPCM7XX.
+- reg			: specifies physical base address and size of the registers.
+- reg-names	: must contain:
+					* "pwm" for the PWM registers.
+					* "fan" for the Fan registers.
+- clocks		: phandle of reference clocks.
+- clock-names	: must contain
+					* "pwm" for PWM controller operating clock.

+Each fan subnode must have one PWM channel and atleast one Fan tach channel.
+
+For PWM channel can be configured cooling-levels to create cooling device.

+		the fan tach channel number that used.
+
+		At least one Fan tach input channel is required
+
+Optional property for each child node:
+- cooling-levels: PWM duty cycle values in a range from 0 to 255
+                  which correspond to thermal cooling states.

+- "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-sysreg.txt
+  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";
+	};
