it's stored in the ->attached_connector of intel_dp and

160672b86b drm/i915/dp: Use clamp for pipe_bpp limits with DSC 
Currently to get the max pipe_bpp with dsc we take the min of
limits->pipe.max_bpp and dsc max bpp (dsc max bpc * 3). This can result
in problems when limits->pipe.max_bpp is less than the computed dsc min bpp
(dsc min bpc * 3).

Replace the min/max functions with clamp while computing
limits->pipe.max/min_bpp to ensure that the pipe_bpp limits are constrained
within the DSC-defined minimum and maximum values.

230a14f4c5 drm/i915/dp: Refactor FEC support check in intel_dp_supports_dsc 
Forward Error Correction is required for DP if we are using DSC but
is optional for eDP.

Currently the helper intel_dp_supports_dsc checks if fec_enable is set for
DP or not. The helper is called after fec_enable is set in crtc_state.

Instead of this a better approach would be to:
first, call intel_dp_supports_dsc to check for DSC support
(along with FEC requirement for DP) and then set fec_enable for DP
(if not already set) in crtc_state.

To achieve this, remove the check for fec_enable in the helper and instead
check for FEC support for DP. With this change the helper
intel_dp_supports_dsc can be called earlier and return early if DSC is
not supported. The structure intel_dp is added to the helper to get the
FEC support for DP.

v2: Pass intel_dp to adjust_limits_for_dsc_hblank_expansion_quirk
instead of deriving it from connector. (Jani)

After a connector is added to the drm_mode_config::connector_list, it's
visible to any in-kernel users looking up connectors via the above list.
Make sure that the connector is properly initialized before such
look-ups, by initializing the connector with

adceb41688 drm/i915/display: add intel_display_conversion.c to hide stuff better 
The __to_intel_display() generics require the definition of struct
drm_i915_private i.e. inclusion of i915_drv.h. Add
intel_display_conversion.c with a __i915_to_display() function to do the
conversion without the intel_display_conversion.h having an implicit
dependency on i915_drv.h.

The long term goal is to remove __to_intel_display() and the
intel_display_conversion.[ch] files altoghether, and this is merely a
transitional step to make the dependencies on i915_drv.h explicit.

17d7072607 drm/i915: extract intel_uncore_trace.[ch] 
The i915_reg_rw tracing is a small isolated part of i915_trace.h. Its
users are orthogonal to the other i915_trace.h users as well, and its
implementation does not require all the includes of i915_trace.h. Split
i915_reg_rw tracing to separate intel_uncore_trace.[ch].

The main underlying goal is to reduce implicit includes of i915_drv.h
from display code.
