Subject: Re: [PATCH v1 1/3] dt-bindings: iio: adc: convert rockchip saradc bindings to yaml
Date: Sun, 15 Mar 2020 15:11:51 +0100	[thread overview]
Message-ID: <a35bdff4-601e-6186-584e-9a0b88cf3dbb@gmail.com> (raw)

Hi Jonathan,

For compatible strings with identical fallback we use 'enum' to combine,
so instead of 3 only 1 additional line is needed for each new SoC patch.

properties:
  compatible:
    oneOf:
      - const: rockchip,saradc
      - const: rockchip,rk3066-tsadc
      - const: rockchip,rk3399-saradc
      - items:
          - enum:
            - rockchip,px30-saradc
            - rockchip,rk3308-saradc
            - rockchip,rk3328-saradc
            - rockchip,rv1108-saradc
          - const: rockchip,rk3399-saradc

[..]
vs
[..]

properties:
  compatible:
    oneOf:
      - const: rockchip,saradc
      - const: rockchip,rk3066-tsadc
      - const: rockchip,rk3399-saradc
      - items:
          - const: rockchip,px30-saradc
          - const: rockchip,rk3399-saradc
      - items:
          - const: rockchip,rk3308-saradc
          - const: rockchip,rk3399-saradc
      - items:
          - const: rockchip,rk3328-saradc
          - const: rockchip,rk3399-saradc
      - items:
          - const: rockchip,rv1108-saradc
          - const: rockchip,rk3399-saradc


Check with:

make ARCH=arm menuconfig
# select Rockchip platform

make -k ARCH=arm64 dt_binding_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/adc/rockchip-saradc.yaml

make -k ARCH=arm dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/adc/rockchip-saradc.yaml

make ARCH=arm64 menuconfig
# select Rockchip platform

make -k ARCH=arm64 dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/adc/rockchip-saradc.yaml

Caution with:

'allOf' and 'additionalProperties: false'
does not completely validate DTS or examples!
