fa509a33e3 drm/xe/display: remove intel_display_step_name() to simplify 
The intel_display_step_name() is an unnecessary extra
indirection. Simplify by just adding a macro to map intel_step_name() to
xe_step_name().

We'll need to temporarily add a compat INTEL_DISPLAY_STEP() for this.

With the previous cleanups, the last remaining user of __i915_printk()
is i915_probe_error(). Switch that to use drm_dbg() and drm_err()

specific cases.

It's not common for drivers to log bug filing requests to begin with,
but these cases are in init, which is most likely to be tested in CI and
least likely to be hit by end users anyway.

e44bc451aa drm/i915/dp_mst: Ensure link parameters are up-to-date for a disabled link 
As explained in the previous patch, the MST link BW reported by branch
devices during topology probing/path resources enumeration depends on
the link parameters programmed to DPCD to be up-to-date. After a sink is
plugged this is not ensured, as those DPCD values start out zeroed. The
target link parameters (for a subsequent modeset) are the maximum that
is supported, so make sure these maximum values are programmed before the
topology probing.

e40fbf6166 drm/i915/dp_mst: Reprobe the MST topology after a link parameter change 
The MST link BW reported by branch devices via the ENUM_PATH_RESOURCES
message depends on the channel coding and link rate/lane count
parameters programmed to DPCD. This is the case at least for some branch
devices, while for others the reported BW is independent of the link
parameters. In any case the DP standard requires the branch device to
adjust the returned value to both account for the different way the BW
for FEC is accounted for (included in the returned value for non-UHBR
and not included for UHBR rates) and to limit the returned value to the
(trained) link BW between the source and first downstream branch
device, see DP v2.0/v2.1 Figure 2-94, DP v2.1 5.9.7. Presumedly this is
also the reason why the standard requires the DPCD link rate/lane count
values being up-to-date before sending the ENUM_PATH_RESOURCES message,
see DP v2.1 2.14.9.4.

Based on the above reprobe the MST topology after the link is retrained
with new link parameters to make sure that the MST link BW tracked in
the MST topology state (via each topology port's full_pbn value) is
up-to-date.

The next patch will make sure that the MST link BW is also kept
up-to-date if the link is disabled.

aa705f7ec6 drm/i915/dp_mst: Reduce the link parameters in BW order after LT failures 
On MST links - at least for some MST branch devices - the list of modes
returned to users on an enabled link depends on the current link
rate/lane count parameters (besides the DPRX link capabilities, any MST
branch BW limit and the maximum link parameters reduced after LT
failures). In particular the MST branch BW limit may depend on the link
rate/lane count parameters programmed to DPCD. After an LT failure and
limiting the maximum link parameters accordingly, users should see a
mode list reflecting these new limits. However with the current fallback
order this isn't ensured, as the new limit could allow for modes
requiring a higher link BW, but these modes will be filtered out due to
the enabled link's lower link BW.

Ensure that the mode list changes in a consistent way after a link
training failure and reducing the link parameters by changing the
fallback order on MST links to happen in BW order.

v2:
- s/INTEL_DP_MAX_SUPPORTED_LANE_COUNTS/INTEL_DP_MAX_SUPPORTED_LANE_CONFIGS
  and s/num_common_lane_counts/num_common_lane_configs to make the
  difference wrt. max lane counts clearer. (Suraj)
- Add a TODO comment to make the SST fallback logic work the same way as
  MST. (Arun)
- Use sort_r()'s default swap function instead of a custom one.
