[RFCv2 10/13] drm: convert plane to properties/state
Rob Clark

Mon Oct 14 19:26:45 CEST 2013
Break the mutable state of a plane out into a separate structure
and use atomic properties mechanism to set plane attributes. This
makes it easier to have some helpers for plane->set_property()
and for checking for invalid params. The idea is that individual
drivers can wrap the state struct in their own struct which adds
driver specific parameters, for easy build-up of state across
multiple set_property() calls and for easy atomic commit or roll-
back.
The same should be done for CRTC, encoder, and connector, but this
patch only includes the first part (plane).
