[PATCH v3 3/6] drm/ingenic: Move IPU scale settings to private state
Paul Cercueil
paul at crapouillou.net
Wed Sep 22 20:55:52 UTC 2021
The IPU scaling information is computed in the plane's ".atomic_check"
callback, and used in the ".atomic_update" callback. As such, it is
state-specific, and should be moved to a private state structure.
