By moving the check from psr_compute_config() to psr_init_dpcd(), we get
to set the dev_priv->psr.sink_support flag only when the panel is
capable of changing power state. An additional benefit is that the check
will be performed only at init time instead of every atomic_check.
This should change the psr_basic IGT failures on HSW to skips.

PSR hardware and hence the driver code for VLV and CHV deviates a lot from
their DDI counterparts. While the feature has been disabled for a long time
now, retaining support for these platforms is a maintenance burden. There
have been multiple refactoring commits to just keep the existing code for
these platforms in line with the rest. There are known issues that need to
be fixed to enable PSR on these platforms, and there is no PSR capable
platform in CI to ensure the code does not break again if we get around to
fixing the existing issues. On account of all these reasons, let's nuke
this code for now and bring it back if a need arises in the future.

For psr block #9, the vbt description has moved to options [0-3] for
TP1,TP2,TP3 Wakeup time from decimal value without any change to vbt
structure. Since spec does not mention from which VBT version this

to change for all the platforms.
There is RCR inplace for GOP team to provide the version number
to make generic change. Since Kabylake with bdb version 209 is having this
change, limiting this change to gen9_bc and version 209+ to unblock google.

L3Bank could be fused off in hardware for debug purpose, and it
is possible that subslice is enabled while its corresponding L3Bank pairs
are disabled. In such case, if MCR packet control register(0xFDC) is
programed to point to a disabled bank pair, a MMIO read into L3Bank range
will return 0 instead of correct values.
However, this is not going to be the case in any production silicon.
Therefore, we only check at initialization and issue a warning should
this really happen.

WaProgramMgsrForCorrectSliceSpecificMmioReads dictate that before any MMIO
read into Slice/Subslice specific registers, MCR packet control
register(0xFDC) needs to be programmed to point to any enabled
slice/subslice pair. Otherwise, incorrect value will be returned.
However, that means each subsequent MMIO read will be forwarded to a
specific slice/subslice combination as read is unicast. This is OK since
slice/subslice specific register values are consistent in almost all cases
across slice/subslice. There are rare occasions such as INSTDONE that this
value will be dependent on slice/subslice combo, in such cases, we need to
program 0xFDC and recover this after. This is already covered by
read_subslice_reg.
Also, 0xFDC will lose its information after TDR/engine reset/power state
change.

however that the coalesced fbdev dirty region was not empty on

This reverts commit dc911f5bd8.
Per the report, no matter what display mode you select with xrandr, the
i915 driver will always select the alternate fixed mode. For the
reporter this means that the display will always run at 40Hz which is
quite annoying. This may be due to the mode comparison.
But there are some other potential issues. The choice of alt_fixed_mode
seems dubious. It's the first non-preferred mode, but there are no
guarantees that the only difference would be refresh rate. Similarly,
there may be more than one preferred mode in the probed modes list, and
the commit changes the preferred mode selection to choose the last one
on the list instead of the first.
(Note that the probed modes list is the raw, unfiltered, unsorted list
of modes from drm_add_edid_modes(), not the pretty result after a
drm_helper_probe_single_connector_modes() call.)
Finally, we already have eerily similar code in place to find the
downclock mode for DRRS that seems like could be reused here.
Back to the drawing board.
Note: This is a hand-crafted revert due to conflicts. If it fails to
backport, please just try reverting the original commit directly.

Commit bc61c97502 ("drm/gma500: Move GEM BO to drm_framebuffer") moved
the gtt_range structure, from being in psb_framebuffer and embedding the
GEM object, to being placed in the drm_framebuffer with the gtt_range
being derived from the GEM object.
The conversion missed out the Medfield subdriver, which was not being
built in the default drm-misc config. Do the trivial fixup here.

drm_framebuffer already holds per-plane pitch and offsets, which is
filled out for us when we create the framebuffer. Nuke our local copy in
the plane struct.

Since drm_framebuffer can now store GEM objects directly, place them
there rather than in our own subclass. As this makes the framebuffer
create_handle and destroy functions the same as the GEM framebuffer
helper, we can reuse those.

v2: Only hold a single reference per framebuffer, not per plane. (Ville)
v3: Drop NULL check in intel_fb_obj. (Ville)

We already have a macro to pull the GEM object from a FB, so use it
everywhere. We'll make use of this later to move the object storage.
