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.
v2:
* move simple encoder to KMS helpers (Daniel)
* remove name argument; simplifies implementation (Gerd)
* don't allocate with devm_ interfaces; unsafe with DRM (Noralf)
Thomas Zimmermann (4):
drm/simple-kms: Add drm_simple_encoder_{init,create}()
drm/ast: Use simple encoder
drm/mgag200: Use simple encoder
drm/qxl: Use simple encoder
