[PATCH 0/3] dt-bindings: iio: adc: Maxim ADC yaml conversions

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

These 3 are all fairly simple (I think) so should be uncontroversial.
My biggest question is with Jacopi and Akinobu are happy to be
explicitly listed as maintainers for these bindings.

Jonathan Cameron (3):

This needs to be moved to the main section when you add 
'additionalProperties'.

Then add an 'else' clause here with:

not:
  required:
    - vref-supply

Or this works too:

properties:
  vref-supply: false

Applied to the togreg branch of iio.git and pushed out as testing for the
autobuilders to play with it.
