[PATCH 0/2] dt-bindings:iio:yaml conversions with xor condition

[Jonathan Cameron <jic23@kernel.org>]

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

These two binding conversions are left from last year because I couldn't
figure out how to do the XOR between spi-cpha and spi-cpol without
using a $ref.  Rob suggested it should work by lifting the $ref block
and putting it inline but that ran into a restriction the dt-schema that
a oneOf is not allowed directly under an allOf.

Line 34 of schema/base.yaml
  allOf:
    items:
      propertyNames:
        enum:
          - $ref
          - if
          - then
          - else
  anyOf: true

I was just about to send a pull request to relax that constraint when I
realized that a top level oneOf was sufficient for this XoR condition
because it rules out more than one of the options being true at the same
time.  Hence the simplified version given here constrains things correctly.

oneOf:
  - required:
      - spi-cpha
  - required:
      - spi-cpol

We don't need to also specify
not:
  required: [spi-cpha, spi-cpol]
as done in earlier versions of these bindings.

One other minor change in patch 2 to make Should -> Must to avoid
confusion.
