Dual microwave down converter module with input RF and LO frequency ranges from 0.5 to 32 GHz and an output IF frequency range from 0.1 to 8 GHz. It consists of a LNA, mixer, IF filter, DSA, and IF amplifier for each down conversion path. Signed-off-by: Kim Seer Paller <kimseer.paller@xxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Closes: https://lore.kernel.org/oe-kbuild-all/202311220624.J7Nqg5h1-lkp@xxxxxxxxx/ --- V2 -> V3: Adjusted indentation to resolve wrong indentation warning. Changed node name to converter. Updated the descriptions to clarify the properties. V1 -> V2: Removed '|' after description. Specified the pins connected to the GPIOs. Added additionalProperties: false. Changed node name to gpio. Aligned < syntax with the previous syntax in the examples. .../bindings/iio/frequency/adi,admfm2000.yaml | 140 ++++++++++++++++++ MAINTAINERS | 7 + 2 files changed, 147 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/frequency/adi,admfm2000.yaml diff --git a/Documentation/devicetree/bindings/iio/frequency/adi,admfm2000.yaml b/Documentation/devicetree/bindings/iio/frequency/adi,admfm2000.yaml new file mode 100644 index 000000000..57844c8b7 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/frequency/adi,admfm2000.yaml @@ -0,0 +1,140 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +# Copyright 2023 Analog Devices Inc. +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/frequency/adi,admfm2000.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ADMFM2000 Dual Microwave Down Converter + +maintainers: + - Kim Seer Paller <kimseer.paller@xxxxxxxxxx> + +description: + Dual microwave down converter module with input RF and LO frequency ranges + from 0.5 to 32 GHz and an output IF frequency range from 0.1 to 8 GHz. + It consists of a LNA, mixer, IF filter, DSA, and IF amplifier for each down + conversion path. + +properties: + compatible: + enum: + - adi,admfm2000 + + switch1-gpios: + items: + - description: + Setting B15 GPIO to high and B16 GPIO to low will result in channel 1 + being in Direct IF mode. + - description: + Setting B15 GPIO to low and B16 GPIO to high will result in channel 1 + being in Mixer mode. + + switch2-gpios: + items: + - description: + Setting K14 GPIO to high and L14 GPIO to low will result in channel 2 + being in Mixer mode. + - description: + Setting K14 GPIO to low and L14 GPIO to high will result in channel 2 + being in Direct IF mode. + + attenuation1-gpios: + description: + Must contain an array of 5 GPIO specifiers, referring to the GPIO pins + connected to the C14, C15, C16, D14, and D15.
