[PATCH v3 09/13] drm: Add encoder_type field to the drm_bridge structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The drm_bridge object models on- or off-chip hardware encoders and
provide an abstract control API to display drivers. In order to help
display drivers creating the right kind of drm_encoder object, expose
the type of the hardware encoder associated with each bridge.
