drm: add plane support v3
Planes are a bit like half-CRTCs. They have a location and fb, but don't drive outputs directly. Add support for handling them to the core KMS code. v2: fix ABI of get_plane - move format_type_ptr to the end v3: add 'flags' field for interlaced support (from Ville) Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Reviewed-by: Rob Clark <rob.clark@linaro.org> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
