Add a binding for the Maxim Integrated MAX5432-MAX5435 family of digital potentiometers. Signed-off-by: Martin Kaiser <martin@xxxxxxxxx> --- changes in v4 - fix the dt bindings - replace ic20 with i2c - document the reg property - add additionalProperties and required changes in v3 - split dt bindings and driver code into separate patches - use yaml format for dt bindings - fix formatting of parameter lists changes in v2 - use MAX5432_ prefix for all defines - fix indentation - convert void * to unsigned long, not to u32 (warning from kbuild test robot) .../bindings/iio/potentiometer/max5432.yaml | 44 ++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/potentiometer/max5432.yaml diff --git a/Documentation/devicetree/bindings/iio/potentiometer/max5432.yaml b/Documentation/devicetree/bindings/iio/potentiometer/max5432.yaml new file mode 100644 index 000000000000..5082f919df2a --- /dev/null +++ b/Documentation/devicetree/bindings/iio/potentiometer/max5432.yaml @@ -0,0 +1,44 @@ +# SPDX-License-Identifier: GPL-2.0 +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/potentiometer/max5432.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Maxim Integrated MAX5432-MAX5435 Digital Potentiometers + +maintainers: + - Martin Kaiser <martin@xxxxxxxxx> + +description: | + Maxim Integrated MAX5432-MAX5435 Digital Potentiometers connected via I2C + + Datasheet: + https://datasheets.maximintegrated.com/en/ds/MAX5432-MAX5435.pdf + +properties: + compatible: + enum: + - maxim,max5432 + - maxim,max5433 + - maxim,max5434 + - maxim,max5435 + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + max5434@28 { + compatible = "maxim,max5434"; + reg = <0x28>; + }; + }; -- 2.11.0
