The General Purpose Registers IOMUXC_GPR are used to select operating
modes for general features in the SoC, usually not related to the IOMUX
itself.

This binding doc is generated based on the exist usage in dts
in order to fix dt schema check failures.

The example in syscon.yaml is invalid and needs change as follows.
However, should I do it in a separate patch cause they're changes for
two irrelevant binding
files or merge into this one ?

Separate patch.

I assume you mean 'simple-mfd'?

Adding that means this example doesn't really even match the
syscon.yaml, so I'd just drop the example.
