Commit 1fd4a5a3 ("drm/connector: Rename legacy TV property") failed
to update all the users of the struct drm_tv_connector_state mode field,
which resulted in a build failure in i915.

However, a subsequent commit in the same series reintroduced a mode
field in that structure, with a different semantic but the same type,
with the assumption that all previous users were updated.

Since that didn't happen, the i915 driver now compiles, but mixes
accesses to the legacy_mode field and the newer mode field, but with the
previous semantics.

This obviously doesn't work very well, so we need to update the accesses
that weren't in the legacy renaming commit.

Fixes: 1fd4a5a3 ("drm/connector: Rename legacy TV property")

cdclk_compute_crawl_and_squash_midpoint() was still assuming
that cd2x divider == 1 (ie. full divider == 2). Remove that
assumption by computing the dividers properly.

We'll also toss in a WARN in case the divider somehow ends
up different between the old and new cdclk configs. That should
never happen given we have div==2 in all the cdclk table entries
for the affected platforms.

If in the future we need a config where the divider also needs
to be changed then we likely need to add an extra step into the
cdclk programming sequence to make sure things stay within
legal limits throughout the process.

There's nothing magical about vlv+ platforms vs. fastboot.
If it works somewhere it should work everywhere, assuming
we've not missed any crucial state checks. That seems unlikely
on older platforms with less state to check anyway.

Just enable fastboot across the board, and the remove the
remnants of the optional stuff (we already removed the
modparam for fastboot anyway).

will return the mode list based on the EDID which was cached during a
previous detection/get_modes call.

This also fixes the NULL deref problem (10085) which was
introduced/revealed by

commit bab87ef4 ("drm/i915: Disable hotplug detection handlers during driver init/shutdown")

After the above change MST connectors will not change state during
driver init/shutdown; thus some of these connectors with no I2C/DDC
adapter registered for them (since the given MST port has no sink
connected) may stay then in the 'unknown' connector status. The
get_modes() hook should not try to use the I2C/DDC adapter in this state
(which would lead to the above NULL deref) which this patch ensures.

v2:
- Remove the redundant check from intel_crt_ddc_get_modes().
- Rebase on latest drm-tip.
- Add Fixes: line / related commit notes.

Prevent accessing the HW from the SDVO/TV get_modes connector hook.
Returning 0 from the hook will make the caller -
drm_helper_probe_single_connector_modes() - return a default/EDID
override mode list to users. This matches the case where
intel_sdvo_get_tv_modes() fails to retrieve the current mode list due to
a HW access failure.

v2: Clarify the commit message wrt. which modes get_modes() returns. (Jouni)

For validation purposes, it might be useful to be able to
force Bigjoiner mode, even if current dotclock/resolution
do not require that.
Lets add such to option to debugfs.

v2: - Apparently intel_dp_need_bigjoiner can't be used, when
      debugfs entry is created so lets just check manually
      the DISPLAY_VER.

v3: - Switch to intel_connector from drm_connector(Jani Nikula)
    - Remove redundant modeset lock(Jani Nikula)
    - Use kstrtobool_from_user for boolean value(Jani Nikula)

v4: - Apply the changes to proper function(Jani Nikula)

v5: - Removed unnecessary check from i915_bigjoiner_enable_show
      (Ville Syrjälä)
    - Added eDP connector check to intel_connector_debugfs_add
      (Ville Syrjälä)
    - Removed debug message in order to prevent dmesg flooding
      (Ville Syrjälä)

v6: - Assume now always that m->private is intel_connector
    - Fixed other similar conflicts

v7: - Move bigjoiner force option to intel_connector(Ville Syrjälä)
    - Use DEFINE_SHOW_STORE_ATTRIBUTE instead of defining fops
      manually.(Ville Syrjälä)

v8: - Pass intel_connector to debugfs_create_file, instead of drm_connector.

Switch to drm_dbg_kms() in the ilk wm code so we see which
device generated the debugs. Need to plumb i915 a bit deeper
to make that happen.
