Should have discussed more in v1 about Rob's comment, but let me explain why this dt-binding makes sense here:
Both i.MX8mp SoC and i.MX93 SoC media block control devices contain a LVDS Display Bridge(LDB) child device. The i.MX93 block control device additionally contains this PDFC child device.
LDB dt-binding [1] is written in a separate file and referenced in i.MX8mp block control dt-binding [2]. So, for the sake of consistency, it makes sense to keep this PDFC dt-binding and reference it together with the LDB one [1] in i.MX93 block control dt-binding [3] in future, doesn't it?
It seems good to have a separate PDFC dt-binding in case it can/will be referenced by multiple parent device dt-bindings.
