Subject: drm/bridge: panel: Propagate bus format/flags
Git-commit: cf52925a862e16ec0151627f64446f0eba853e45
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Propagate bus format/flags so that the previous bridge element in the
chain knows which input format the panel bridge expects.
v11:
* Fix a typo in the subject
* Update the commit message so it's readable by itself
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
