They don't seem necessary Not necessary to document or use? The latter requires the former. If your device only supports one timing mode, then you don't need them because it should be implied and the driver can just tell the SPI subsystem what mode it requires. If the device can support multiple timing modes, then you should document that you are using the properties. > .../bindings/iio/accel/adi,adis16240.yaml | 51 +++++++++++++++++++ > 1 file changed, 51 insertions(+) > create mode 100644 Documentation/devicetree/bindings/iio/accel/adi,adis16240.yaml > > diff --git a/Documentation/devicetree/bindings/iio/accel/adi,adis16240.yaml b/Documentation/devicetree/bindings/iio/accel/adi,adis16240.yaml > new file mode 100644 > index 000000000000..9a4cd12c4818 > --- /dev/null > +++ b/Documentation/devicetree/bindings/iio/accel/adi,adis16240.yaml > @@ -0,0 +1,51 @@ > +# SPDX-License-Identifier: GPL-2.0 > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/iio/accel/adi,adis16240.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: ADIS16240 Programmable Impact Sensor and Recorder driver > + > +maintainers: > + - Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx> > + > +description: | > + ADIS16240 Programmable Impact Sensor and Recorder driver that supports > + SPI interface. > + https://www.analog.com/en/products/adis16240.html > + > +properties: > + compatible: > + enum: > + - adi,adis16240 > + > + reg: > + maxItems: 1 > + > + interrupts: > + maxItems: 1 > + > +required: > + - compatible > + - reg > + - interrupts > + > +examples: > + - | > + #include <dt-bindings/gpio/gpio.h> > + #include <dt-bindings/interrupt-controller/irq.h> > + spi0 { > + #address-cells = <1>; > + #size-cells = <0>; > + > + /* Example for a SPI device node */ > + accelerometer@0 { > + compatible = "adi,adis16240"; > + reg = <0>; > + spi-max-frequency = <2500000>; > + spi-cpol; > + spi-cpha; > + interrupt-parent = <&gpio0>; > + interrupts = <0 IRQ_TYPE_LEVEL_HIGH>; > + }; > + }; > -- > 2.23.0 >
