[PATCH v6 01/12] drm/atomic: Handle picture_aspect_ratio in atomic core

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

 



This is only used in i915, which had used its own non-taomic way to
deal with the picture aspect ratio. Move selected aspect_ratio to
atomic state and use the atomic state in the affected i915 connectors.
