Many DRM drivers implement an encoder with an empty implementation. This
patchset adds drm_simple_encoder_init() and drm_simple_encoder_create(),
which can be used by drivers instead. Except for the destroy callback, the
simple encoder's implementation is empty.
The patchset also converts 4 encoder instances to use the simple-encoder
helpers. But there are at least 11 other drivers which can use the helper
and I think I did not examine all drivers yet.
The patchset was smoke-tested on mgag200 by running the fbdev console
and Gnome on X11.
Thomas Zimmermann (6):
drm: Move initialization of encoder into an internal function
drm: Add drm_simple_encoder_{init,create}()
drm/ast: Use simple encoder
drm/mgag200: Use simple encoder
drm/qxl: Use simple encoder
drm/simple-pipe: Use simple encoder
