-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>;

-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

+Description
+-----------
+
+This driver supprts hardware monitoring for Analog Devices ADP1050 Digital
+Controller for Isolated Power Supply with PMBus interface.
+
+The ADP1050 is an advanced digital controller with a PMBus™
+interface targeting high density, high efficiency dc-to-dc power
+conversion used to monitor system temperatures, voltages and currents.
+Through the PMBus interface, the device can monitor input/output voltages,
+input current and temperature.
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate
+the devices explicitly.
+Please see Documentation/i2c/instantiating-devices.rst for details.
+
+Platform data support

+
+The driver supports standard PMBus driver platform data.
