Signed-off-by: Marcelo Schmitt --- Changes v1 -> v2 - Made "cs" the default adi,sdi-pin value for PulSAR devices. - Dropped AD7694 and the related vio pin checks. I forgot the ad4000 driver fails if VIO is not provided so I was wrong when I said AD7694 was software compatible with the other ADCs. I see now AD7694 also doesn't have SDI pin. Aside from the VIO and SDI pins, AD7694 is similar to AD7685 both being 16-bit precision 250kSPS pseudo-differential ADCs. The AD7683 part mentioned in v1 discussion is similar to AD7988-1, both 16-bit pseudo-differential 100kSPS. To avoid complicating things, I dropped support for AD7694. AD7685 and AD7988-1 are the parts with features similar to AD7694 and AD7683, respectively. .../bindings/iio/adc/adi,ad4000.yaml | 71 +++++++++++++++++++ 1 file changed, 71 insertions(+) diff --git a/Documentation/devicetree/bindings/iio/adc/adi,ad4000.yaml b/Documentation/devicetree/bindings/iio/adc/adi,ad4000.yaml index e413a9d8d2a2..4dbb3d2876f9 100644 --- a/Documentation/devicetree/bindings/iio/adc/adi,ad4000.yaml +++ b/Documentation/devicetree/bindings/iio/adc/adi,ad4000.yaml @@ -19,6 +19,20 @@ description: | https://www.analog.com/media/en/technical-documentation/data-sheets/ad4020-4021-4022.pdf https://www.analog.com/media/en/technical-documentation/data-sheets/adaq4001.pdf https://www.analog.com/media/en/technical-documentation/data-sheets/adaq4003.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7685.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7686.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7687.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7688.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7690.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7691.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7693.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7942.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7946.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7980.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7982.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7983.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7984.pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/ad7988-1_7988-5.pdf $ref: /schemas/spi/spi-peripheral-props.yaml# @@ -63,6 +77,37 @@ properties: - const: adi,adaq4003 + - const: adi,ad7946 + - items: + - enum: + - adi,ad7942 + - const: adi,ad7946 + + - const: adi,ad7983 + - items: + - enum: + - adi,ad7980 + - adi,ad7988-5 + - adi,ad7686 + - adi,ad7685 + - adi,ad7988-1 + - const: adi,ad7983 + + - const: adi,ad7688 + - items: + - enum: + - adi,ad7693 + - adi,ad7687 + - const: adi,ad7688 + + - const: adi,ad7984 + - items: + - enum: + - adi,ad7982 + - adi,ad7690 + - adi,ad7691 + - const: adi,ad7984 + reg: maxItems: 1 @@ -133,6 +178,32 @@ required: - ref-supply allOf: + # Single-channel PulSAR devices have SDI either tied to VIO, GND, or host CS. + - if: + properties: + compatible: + contains: + enum: + - adi,ad7685 + - adi,ad7686 + - adi,ad7687 + - adi,ad7688 + - adi,ad7690 + - adi,ad7691 + - adi,ad7693 + - adi,ad7942 + - adi,ad7946 + - adi,ad7980 + - adi,ad7982 + - adi,ad7983 + - adi,ad7984 + - adi,ad7988-1 + - adi,ad7988-5 + then: + properties: + adi,sdi-pin: + enum: [ high, low, cs ] + default: cs # The configuration register can only be accessed if SDI is connected to MOSI - if: required:
