[PATCH 1/2] dt-bindings: iio: ad7192: Fix Regulator Properties

[Maxime Ripard]

The AD7192 binding describes two regulator properties, avdd-supply and
dvdd-supply, but describes it as a constant string that must be avdd and
dvdd. This is wrong since a *-supply property is actually a phandle, and
results in warnings when the example is validated (or any device tree using
that device, for that matter).

Let's remove that requirement.

[PATCH 2/2] dt-bindings: iio: ad7192: Fix DTC warning in the example

[Maxime Ripard]

The example contains an SPI bus and device, but doesn't have the
appropriate size and address cells size.

This creates a DTC warning when the example is compiled since the default
ones will not match what the device uses. Let's add them to remove that
warning.

Thanks for clearing this up.
