The 'atomic' mechanism allows for multiple properties to be updated,
checked, and commited atomically. This will be the basis of atomic-
modeset and nuclear-pageflip.
The basic flow is:
state = dev->atomic_begin();
for (... one or more ...)
obj->set_property(obj, state, prop, value);
if (dev->atomic_check(state))
dev->atomic_commit(state);
dev->atomic_end(state);
The split of check and commit steps is to allow for ioctls with a
test-only flag (which would skip the commit step).

+ * DOC: atomic state helpers
+ *
+ * Base helper atomic state and functions. Drivers are free to either
+ * use these as-is, extend them, or completely replace them, in order
+ * to implement the atomic KMS API.
+ *
+ * A naive driver, with no special constraints or hw support for atomic
+ * updates may simply add the following to their driver struct:
+ *
+ * .atomic_begin = drm_atomic_begin,
+ * .atomic_set_event = drm_atomic_set_event,
+ * .atomic_check = drm_atomic_check,
+ * .atomic_commit = drm_atomic_commit,
+ * .atomic_end = drm_atomic_end,
+ * .atomics = &drm_atomic_funcs,
+ *
+ * In addition, if you're plane/crtc doesn't already have it's own custom
+ * properties, then add to your plane/crtc_funcs:
+ *
+ * .set_property = drm_atomic_{plane,crtc}_set_property,
+ *
+ * Unlike the crtc helpers, it is intended that the atomic helpers can be
+ * used piecemeal by the drivers, either using all or overriding parts as
+ * needed.
+ *
+ * A driver which can have (for example) conflicting modes across multiple
+ * crtcs (for example, bandwidth limitations or clock/pll configuration
+ * restrictions), can simply wrap drm_atomic_check() with their own
+ * driver specific .atomic_check() function.
+ *
+ * A driver which can support true atomic updates can wrap
+ * drm_atomic_commit().
+ *
+ * A driver with custom properties should override the appropriate get_state(),
+ * check_state(), and commit_state() functions in .atomics if it uses
+ * the drm-atomic-helpers. Otherwise it is free to use &drm_atomic_funcs
+ * as-is.
