Chris Wilson 366e292df6 drm/sun4i: Remove open-coded drm_connector_register_all()
drm_dev_register() will now register all known connectors, so we no
longer have to do so manually.

Daniel Vetter a742946a1b drm: Don't call drm_dev_set_unique from platform drivers
Since

commit e112e593b2
Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org>

    drm: use dev_name as default unique name in drm_dev_alloc()

we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name

v2: Rebase on top of mediatek.

Maxime Ripard 3d6bd9065b drm/sun4i: remove simplefb at probe
If simplefb was setup by our bootloader and enabled in the DT, we will have
a first framebuffer loaded in our system.

However, as soon as our DRM driver will load, it will reset the controller,
initialise it and, if the framebuffer emulation is enabled, register a
second framebuffer device.

This is obviously pretty bad, since the first framebuffer will be some kind
of a black hole, with memory still reserved that we can write to safely,
but not displayed anywhere.

Make sure we remove that framebuffer when we probe so we don't end up in
that situation.

Maxime Ripard 29e57fab97 drm: sun4i: Add RGB output
One of the A10 display pipeline possible output is an RGB interface to
drive LCD panels directly. This is done through the first channel of the
TCON that will output our video signals directly.

Maxime Ripard 9026e0d122 drm: Add Allwinner A10 Display Engine support
The Allwinner A10 and subsequent SoCs share the same display pipeline, with
variations in the number of controllers (1 or 2), or the presence or not of
some output (HDMI, TV, VGA) or not.

Add a driver with a limited set of features for now, and we will hopefully
support all of them eventually
