Why every device here has ldb child? Why camera has ldb?

I guess I see what you mean... Would something like the following change
be acceptable?

---
if:
  properties:
    compatible:
      contains:
        const: nxp,imx94-lvds-csr
then:
  patternProperties:
    "^ldb@[0-9a-f]+$":
      type: object
      $ref: /schemas/display/bridge/fsl,ldb.yaml#

In if:then: you only narrow the existence or constraints, so "if:not:
.... then: patternProperties:.... ^ldb@[0-9a-f]+$:false". The node
should still be defined in top level.
