This has quick a bit midlayer taste to it ... I think having this as a
helper would be cleaner ...
The other bit is drm_encoder->possible_crtcs. If we do create a helper for
these, lets at least try to make them not suck too badly :-) Otherwise I
guess it would be time to officially document what exactly possible_crtcs
== 0 means from an uabi pov.

[PATCH v2] drm: Bump encoder limit from 32 to 64
Assuming that GPUs would never have even close to 32 separate video
encoders is quite honestly a pretty reasonable assumption. Unfortunately
we do not live in a reasonable world, as it looks like it is actually
possible to find devices that will create more drm_encoder objects then
this. Case in point: the ThinkPad P71's discrete GPU, which exposes 1
eDP port and 5 DP ports. On the P71, nouveau attempts to create one
encoder for the eDP port, and two encoders for each DP++/USB-C port
along with 4 MST encoders for each DP port. This comes out to 35

[RFC v2 06/20] drm/nouveau/kms: Search for encoders' connectors properly
While the way we find the associated connector for an encoder is just
fine for legacy modesetting, it's not correct for nv50+ since that uses
atomic modesetting. For reference, see the drm_encoder kdocs.
Fix this by removing nouveau_encoder_connector_get(), and replacing it
with nv04_encoder_get_connector(), nv50_outp_get_old_connector(), and
nv50_outp_get_new_connector().
v2:
* Don't line-wrap for_each_(old|new)_connector_in_state in

[PATCH 6/8] drm/nouveau/kms/nv50-: Lookup current encoder/crtc from atomic state
Despite being an atomic driver, nouveau has a lot of leftover code that
relies on retrieving information regarding the new atomic state from
members of drm_encoder and drm_crtc. The first field being used,
drm_encoder.crtc, is deprecated for atomic drivers. The second field being
used is drm_crtc.state, which is only really sensible to use outside of an
atomic modeset.
So, add some helpers to lookup the current crtc for a given outp from the
atomic state. Th...
