I look through other yaml and find below format could achieve the restriction on one property: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/tree/Documentation/devicetree/bindings/usb/gpio-sbu-mux.yaml?h=usb-testing#n54 - if: required: - mode-switch then: required: - enable-gpios If mode-switch is present, then enable-gpios is required. If not, then enable-gpios is not required. For my case, if compatible contains "fsl,imx95-usb-phy" and orientation-switch is present, then this schema needs to refer to usb-switch.yaml. If not. then this schema will not refer to usb-switch.yaml. So the subject could reflect the thing this patch does. Is this feasible? If not, could you give some advices?
