[PATCH v6 04/12] drm/exynos: atomic phase 2: wire up state reset(), duplicate() and destroy()

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

 



From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

Set CRTC, planes and connectors to use the default implementations from
the atomic helper library. The helpers will work to keep track of state
for each DRM object.
