We tend to rapidly find someone has a board where the interrupt isn't wired. Given it's usually fairly easy to implement the no interrupt case by just having an alternative iio_info structure in the driver it would be good to have that from the start if possible. > + > +additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/gpio/gpio.h> > + #include <dt-bindings/interrupt-controller/irq.h> > + i2c0 { > + #address-cells = <1>; > + #size-cells = <0>; > + > + /* Example for a I2C device node */ > + accelerometer@62 { > + compatible = "nxp,fxls8962af"; > + reg = <0x62>; > + interrupt-parent = <&gpio0>; > + interrupts = <0 IRQ_TYPE_LEVEL_HIGH>; > + }; > + }; > + - | > + #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 = "nxp,fxls8962af"; > + reg = <0>; > + spi-max-frequency = <4000000>; > + interrupt-parent = <&gpio0>; > + interrupts = <0 IRQ_TYPE_LEVEL_HIGH>; > + }; > + };
