So that the previous bridge element in the chain knows which input format the panel bridge expects.
v10: * Add changelog to the commit message
v8 -> v9: * No changes
v7: * Set atomic state hooks explicitly
v4 -> v6: * Not part of the series
v3: * Adjust things to match the new bus-format negotiation approach * Use drm_atomic_helper_bridge_propagate_bus_fmt * Don't implement ->atomic_check() (the core now takes care of bus flags propagation)
v2: * Adjust things to match the new bus-format negotiation approach
