drm: rcar-du: Fix crash when using LVDS1 clock for CRTC
On D3 and E3 platforms, the LVDS encoder includes a PLL that can
generate a clock for the corresponding CRTC, used even when the CRTC
output to a non-LVDS port. This mechanism is supported by the driver,
but the implementation is broken in dual-link LVDS mode. In that case,
the LVDS1 drm_encoder is skipped, which causes a crash when trying to
access its bridge later on.
Fix this by storing bridge pointers internally instead of retrieving
them from the encoder. The rcar_du_device encoders field isn't used
anymore and can be dropped.

drm: Add default modes for connectors in unknown state
The DRM CRTC helpers add default modes to connectors in the connected
state if no mode can be retrieved from the connector. This behaviour is
useful for VGA or DVI outputs that have no connected DDC bus. However,
in such cases, the status of the output usually can't be retrieved and
is reported as connector_status_unknown.
Extend the addition of default modes to connectors in an unknown state
to support outputs that can retrieve neither the modes nor the
connection status.

drm/i915: Fix mismatch between misplaced vma check and vma insert
When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.
However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.
commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.

drm/amd/display: HP Reverb G2 VR fails to light up
[Why]
Many VR headsets require a HSYNC width of 4, but DCN

DCN20.

There is a warning that triggers when pstate takes too long.
Pstate can take up to ~200us on Linux without hanging but

Silence this by checking for -EPROBE_DEFER and using dev_err_probe() so
we set a deferred reason in case a dependency fails to probe (which
quickly happens on small config/DT changes due to the rather long probe
chain which can include bridges, phys, panels, backights, leds, etc.).
This also removes the only DRM_DEV_ERROR() usage, the rest of the driver
uses dev_err().

- Fix the ordering of allocating a vector for an interrupt. The order
