Subject: drm: bridge: Mark deprecated operations in drm_bridge_funcs
Git-commit: 3667bbd7829059870dff1b6cb4c8eca5aa80e24d
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
drm_bridge_funcs includes several duplicated operations as atomic
variants have been added over time.
New bridge drivers shall use the atomic variants - mark the deprecated
operations to try to avoid usage in new bridge drivers.
v2:
- Drop out-dated comment about state in mode_set (Laurent)
- Added missing "the" in a description
