But can the device do something useful without one?

If not, you could omit the clock-lanes property. It wasn't documented earlier either albeit the example had it for some reason. > + > + data-lanes: > + minItems: 1 > + maxItems: 4 > + > + remote-endpoint: true > + > + required: > + - remote-endpoint > + > + required: > + - reg > + > +required: > + - compatible > + - reg > + - reg-names > + - interrupts > + - syscon-camerrx > + > +additionalProperties: false > + > +examples: > + - | > + #include > + > + cal: cal@4845b000 { > + compatible = "ti,dra72-cal"; > + reg = <0x4845B000 0x400>, > + <0x4845B800 0x40>, > + <0x4845B900 0x40>; > + reg-names = "cal_top", > + "cal_rx_core0", > + "cal_rx_core1"; > + interrupts = ; > + syscon-camerrx = <&scm_conf 0xE94>; > + > + ports { > + #address-cells = <1>; > + #size-cells = <0>; > + > + csi2_0: port@0 { > + reg = <0>; > + csi2_phy0: endpoint@0 { > + remote-endpoint = <&csi2_cam0>; > + clock-lanes = <0>; > + data-lanes = <1 2>; > + }; > + }; > + }; > + }; > + > + i2c5: i2c@4807c000 { > + status = "okay"; > + clock-frequency = <400000>; > + #address-cells = <1>; > + #size-cells = <0>; > + > + ov5640@3c { > + compatible = "ovti,ov5640"; > + reg = <0x3c>; > + > + clocks = <&clk_ov5640_fixed>; > + clock-names = "xclk"; > + > + port { > + csi2_cam0: endpoint@0 { > + remote-endpoint = <&csi2_phy0>; > + clock-lanes = <0>; > + data-lanes = <1 2>; > + }; > + }; > + }; > + }; > + > +... > diff --git a/Documentation/devicetree/bindings/media/ti-cal.txt b/Documentation/devicetree/bindings/media/ti-cal.txt > deleted file mode 100644 > index b7bf8492dc2a..000000000000 > --- a/Documentation/devicetree/bindings/media/ti-cal.txt > +++ /dev/null > @@ -1,82 +0,0 @@ > -Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL) > ------------------------------------------------------- > - > -The Camera Adaptation Layer (CAL) is a key component for image capture > -applications.
