Good point, I'll add properties: bus-type: enum: [ 3, 4 ] required: - bus-type Should I also change unevaluatedProperties to additionalProperties for the endpoint node, to reject any other property (and the explicitly list remote-endpoint as an allowed property) ? The result would be endpoint: $ref: /schemas/media/video-interfaces.yaml# additionalProperties: false properties: bus-type: enum: [ 3, 4 ] data-lanes: true remote-endpoint: true required: - bus-type - data-lanes - remote-endpoint > > + > > + required: > > + - endpoint > > + > > +required: > > + - compatible > > + - reg > > + - reg-names > > + - interrupts > > + - clocks > > + - clock-names > > + - power-domains > > + - brcm,num-data-lanes > > + - port > > + > > +additionalProperties: False > > + > > +examples: > > + - | > > + #include <dt-bindings/clock/bcm2835.h> > > + #include <dt-bindings/interrupt-controller/arm-gic.h> > > + #include <dt-bindings/power/raspberrypi-power.h> > > + csi1: csi@7e801000 { > > + compatible = "brcm,bcm2835-unicam"; > > + reg = <0x7e801000 0x800>, > > + <0x7e802004 0x4>; > > + reg-names = "unicam", "cmi"; > > + interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>; > > + clocks = <&clocks BCM2835_CLOCK_CAM1>, > > + <&firmware_clocks 4>; > > + clock-names = "lp", "vpu"; > > + power-domains = <&power RPI_POWER_DOMAIN_UNICAM1>; > > + brcm,num-data-lanes = <2>; > > + port { > > + csi1_ep: endpoint { > > + remote-endpoint = <&imx219_0>; > > + data-lanes = <1 2>; > > + }; > > + }; > > + }; > > +... > > diff --git a/MAINTAINERS b/MAINTAINERS > > index fada59148cb5..e50a59654e6e 100644 > > --- a/MAINTAINERS > > +++ b/MAINTAINERS > > @@ -3997,6 +3997,12 @@ N: bcm113* > > N: bcm216* > > N: kona > > > > +BROADCOM BCM2835 CAMERA DRIVERS > > +M: Raspberry Pi Kernel Maintenance <kernel-list@raspberrypi.com> > > +L: linux-media@vger.kernel.org > > +S: Maintained > > +F: Documentation/devicetree/bindings/media/brcm,bcm2835-unicam.yaml > > + > > BROADCOM BCM47XX MIPS ARCHITECTURE > > M: Hauke Mehrtens <hauke@hauke-m.de> > > M: Rafał Miłecki <zajec5@gmail.com>
