We have a few TGL machines in our CI and it is mostly green with
failures in tests that will not impact future Linux installations.
Also there is no warnings, errors, flickering or any visual defects
while doing ordinary tasks like browsing and editing documents in a
dual monitor setup.
As a reminder i915.require_force_probe was created to protect
future Linux installation's iso images that might contain a
kernel from the enabling time of the new platform. Without this
protection most of linux installation was recommending
nomodeset option during installation that was getting stick
there after installation.

This workaround appears under two different numbers (and with somewhat

The bspec description for this workaround tells us to program
0xFFFF_FFFF into both FBC_RT_BASE_ADDR_REGISTER_* registers, but we've
previously found that this leads to failures in CI. Our suspicion is
that the failures are caused by this valid turning on the "address valid
bit" even though we're intentionally supplying an invalid address.
Experimentation has shown that setting all bits _except_ for the
RT_VALID bit seems to avoid these failures.
v2:
- Mask off the RT_VALID bit. Experimentation with CI trybot indicates
that this is necessary to avoid reset failures on BCS.
v3:
- Program RT_BASE before RT_BASE_UPPER so that the valid bit is turned
off by the first write. (Chris)

i915 can enable aux device nodes for DP MST by calling
drm_dp_mst_connector_late_register()/
drm_dp_mst_connector_early_unregister(),
so let's hook that up.
Changes since v1:
* Call intel_connector_register/unregister() from
intel_dp_mst_connector_late_register/unregister() so we don't lose
error injection - Ville Syrjälä
Changes since v2:
* Don't forget to clean up if intel_connector_register() fails - Ville

and remove each ras IP's own debugfs creation
this is required to fix ras when the driver does not use the drm load
and unload callbacks due to ordering issues with the drm device node.
