Subject: [PATCH v2 1/6] drm/plane: Pass old state to ->atomic_update()
Date: Tue, 25 Nov 2014 12:09:44 +0100	[thread overview]
Message-ID: <1416913789-23209-1-git-send-email-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding@nvidia.com>

In most situations it will be useful to have the old state passed to the
->atomic_update() callback. For example if a plane is being disabled the
new state's .crtc field will be NULL, but some drivers may rely on this
field to program the CRTCs registers.

v2: rename variable to old_plane_state and remove redundant comment as
suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to
drm-next and add a hunk for pending MSM mdp5 changes
