This adds device tree bindings for the one-bit-adc-dac. Signed-off-by: Cristian Pop <cristian.pop@xxxxxxxxxx> V1->V2 - I am aware of the recommendation of rename/move this driver. Should we consider "drivers/io/gpio.c"? - Add .yaml file - Remove blank lines, remove unnecessary coma - Remove macros for channels - Check if channel is input for write_raw - Use labels instead of extend_name - Fix channel indexing - Use "sizeof(*channels)" in devm_kcalloc() - Remove assignment: " indio_dev->dev.parent = &pdev->dev;" - Remove "platform_set_drvdata" - Remove "adi" from compatible string since is not ADI specific driver. --- .../bindings/iio/addac/one-bit-adc-dac.yaml | 89 +++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/addac/one-bit-adc-dac.yaml diff --git a/Documentation/devicetree/bindings/iio/addac/one-bit-adc-dac.yaml b/Documentation/devicetree/bindings/iio/addac/one-bit-adc-dac.yaml new file mode 100644 index 000000000000..dbed0f3b1ca4 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/addac/one-bit-adc-dac.yaml @@ -0,0 +1,89 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +# Copyright 2020 Analog Devices Inc. +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/addac/one-bit-adc-dac.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Analog Devices one bit ADC DAC driver + +maintainers: + - Cristian Pop <cristian.pop@xxxxxxxxxx> + +description: | + One bit ADC DAC driver + +properties: + compatible: + enum: + - adi,one-bit-adc-dac + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + + in-gpios: + description: Input GPIOs + + out-gpios: + description: Output GPIOs + +required: + - compatible + - in-gpios + - out-gpios + +patternProperties: + "^channel@([0-9]|1[0-5])$": + type: object + description: | + Represents the external channels which are connected to the ADDAC. + + properties: + reg: + maxItems: 1 + description: | + The channel number. + + label: + description: | + Unique name to identify which channel this is. + + required: + - reg + +additionalProperties: false + +examples: + - | + one-bit-adc-dac@0 { + compatible = "one-bit-adc-dac"; + + #address-cells = <1>; + #size-cells = <0>; + + in-gpios = <&gpio 17 0>, <&gpio 27 0>; + out-gpios = <&gpio 23 0>, <&gpio 24 0>; + + channel@0 { + reg = <0>; + label = "i_17"; + }; + + channel@1 { + reg = <1>; + label = "i_27"; + }; + + channel@2 { + reg = <2>; + label = "o_23"; + }; + + channel@3 { + reg = <3>; + label = "o_24"; + }; + }; -- 2.17.1
