[PATCH 2/3] iio: potentiometer: mcp4531: Add device tree binding documentation
From: Florian Vaussard
Date: Tue Jun 21 2016 - 02:56:07 EST
Add the device tree documentation for all the supported parts. Apart the
compatible string and standard I2C binding, no other binding is currently
needed.

+ driver
+
+The node for this driver must be a child node of a I2C controller, hence
+all mandatory properties for your controller must be specified. See directory:
+
+ Documentation/devicetree/bindings/i2c
+
+for more details.
+
+Required properties:
+ - compatible: Must be one of the following, depending on the
+ model:
