Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

This change is to avoid over-specification of the TEOT timing
parameter, which is derived from software in current design.
Supposed that THS-TRAIL and THS-EXIT have the minimum values,
i.e., 60 and 100 in ns. If SW is overriding the HW default,
the TEOT value becomes 150 ns, approximately calculated by
the following formula.
DIV_ROUND_UP(60/50)*50 + DIV_ROUND_UP(100/50))*50/2, where 50
is LP Escape Clock time in ns.
The TEOT value 150 ns is larger than the maximum value,
around 136 ns if UI is 1.8ns, (105 ns + 12*UI, defined by MIPI
DPHY specification).
However, the TEOT value will meet the specification if THS-TRAIL
is set to the HW default, instead of software overriding.
The timing change is made for both data lane and clock lane.
v1: initial version.
v2: change clock lane dphy timings.
v3: remove calculation of trail cnt.
v4: rebase.

The Forcewake timeout issue has been observed on Gen 12.0 and above.
To address this, disable Render Power-Gating (RPG) during live self-tests
for these generations. The temporary workaround 'drm/i915/mtl: do not
enable render power-gating on MTL' disables RPG globally, which is
unnecessary since the issues were only seen during self-tests.

On ILK-IVB only PCH outputs use shared dplls. Move the relevant
intel_disable_shared_dpll() into ilk_pch_post_disable() to make
that clear (and if we extend the dpll mgr to cover all plls we need
different enable/disable points anyway for the PCH vs. CPU eDP cases).
The intel_enable_shared_dpll() counterpart was already in
ilk_pch_enable() anyway, so this is the more symmetric place for the
disable as well.

Currently we loop over all joined pipes and enable/disable the
shared dplls for each. We don't really have to do that since
all joined pipes will be using the same dpll. So let's just do
the enable/disable once for the whole set of joined pipes.
We can still keep tracking the dpll active set as pipes as long
as we remember to flip the bits for all the joined pipes on one go.

Pull timer cleanups from Thomas Gleixner:
"A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to
the callback pointer. This turned out to be suboptimal for the
upcoming Rust integration and is obviously a silly implementation to
begin with.
This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
with hrtimer_setup(T, cb);
The conversion was done with Coccinelle and a few manual fixups.
Once the conversion has completely landed in mainline, hrtimer_init()
will be removed and the hrtimer::function becomes a private member"

We now always set vrr.flipline, vmin, and vmax for all platforms that
support VRR. Therefore, we should set all TRANS_VRR_CTL bits except
VRR_ENABLE. Without this, the readback for these bits will fail because we
only read vrr.flipline, vmin, and vmax if TRANS_VRR_CTL has the
FLIPLINE_EN bit set.
For platforms that always have the VRR Timing Generator enabled,
the FLIPLINE_EN bit is always set in TRANS_VRR_CTL during
intel_transcoder_vrr_enable(). However, for the remaining platforms
(that do not always have the VRR Timing Generator enabled) if a full
modeset doesn't occur and VRR is not enabled, the bit is not set.
This results in a mismatch between the software state and hardware state
because the software state expects VRR timings like flipline, vmin, and
vmax to be set, but the readout for these doesn't happen since the
FLIPLINE_EN bit is not set in TRANS_VRR_CTL.
To avoid this mismatch, write trans_vrr_ctl in
intel_vrr_set_transcoder_timings() even when VRR is not enabled
for platforms that do not have the VRR Timing Generator always enabled.

Currently, the VRR timing generator is used only when VRR is enabled by
userspace for sinks that support VRR. Starting with PTL+, gradually move
away from the legacy timing generator and use the VRR timing generator
for both variable and fixed timings.
Note: For platforms where we always enable the VRR timing generator,
the LRR fastset is not allowed to avoid live programming of vrr.guardband
with VRR TG enabled. This effectively breaks the LRR fastset functionality
for these platforms and needs to be addressed.
v2: Use this for PTL for now to avoid losing LRR fastset for older
platforms. (Ville)

VRR with joiner is currently disabled as it still needs some work to
correctly sequence the primary and secondary transcoders. However, we can
still use VRR Timing generator in fixed refresh rate for joiner and since
it just need to program vrr timings once and does not involve changing
timings on the fly. We still need to skip the VRR and LRR for joiner.
To achieve this set vrr.in_range to 0 for joiner case, so that we do not
try VRR and LRR for the joiner case.
v2: Avoid checks for secondary pipes, where not required. (Ville)

Since the vrr.guardband can now change for platforms that always use the
VRR Timing Generator, and it is unsafe to reprogram the guardband on the
fly, move the guardband and pipeline_full checks from the pure !fastboot
path and add a check for intel_vrr_always_use_vrr_tg().
For older platforms the vrr.guardband change happens when VRR Timing
generator is off. For the platforms that always use the VRR Timing
Generator, this will prevent reprogramming the vrr.guardband without a
full modeset. However, this will disrupt LRR functionality for these
platforms.
v2: Modify the check to avoid breaking the LRR on older platform.

v3: Correct the oversight of not removing the lines from the original
location. (Ville)

During modeset enable sequence, program the fixed timings, and turn on the

For platforms that enable VRR TG only for variable timings, the
VRR_CTL.VRR_ENABLE bit indicates VRR is active. For platforms that
always have VRR TG enabled, the VRR_CTL.VRR_ENABLE bit indicates VRR
is active only when not in fixed refresh rate mode.

For platforms for which vrr timing generator is always set, VRR_CTL
enable bit does not need to toggle, so modify the vrr_{enable/disable}
for this.
At the moment the helper intel_vrr_always_use_vrr_tg() return false for
all cases. This will be set later when all other bits are in place.

LRR and Vmax can be computed only if VRR is supported and vrr.in_range
is set. Currently we proceed with vrr timings only for VRR supporting
panels and return otherwise. For using VRR TG with fix timings, need to
continue even for panels that do not support VRR.
To achieve this, refactor the condition for computing vmax and
update_lrr so that we can continue for fixed timings for panels that do
not support VRR.
v2: Set vmax = vmin for non VRR panels. (Ville)

Currently the variable timings are supported only for DP and eDP and not
for DP MST. Call intel_vrr_compute_config() for MST which will configure
fixed refresh rate timings irrespective of whether VRR is supported or
not. Since vrr_capable still doesn't have support for DP MST this will be
just treated as non VRR case and vrr.vmin/vmax/flipline will be all set
to adjusted_mode->crtc_vtotal.
This will help to move away from the legacy timing generator and
always use VRR timing generator by default.
With this change, we need to exclude MST in intel_vrr_is_capable for
now, to avoid having LRR with MST.
v2: Exclude MST in intel_vrr_is_capable() for now. (Ville)

specific platform checks
The HDMI vs. not scanline offset stuff no longer applies to the
latest platforms, so using HAS_DDI() is a bit confusing. Replace
with a more specific set of conditions.
Also let's just deal with the platform types in the if ladder
itself, and handle the HDMI vs. not within the specific branch
for those platforms.

The Panel Power Sequencer lock held on an eDP port (a) blocks a DP AUX
transfer on another port (b), since the PPS lock is device global, thus
shared by all ports. The PPS lock can be held on port (a) for a longer
period due to the various PPS delays (panel/backlight on/off,
power-cycle delays). This in turn can cause an MST down-message request
on port (b) time out, if the above PPS delay defers the handling of the
reply to the request by more than 100ms: the MST branch device sending
the reply (signaling this via the DP_DOWN_REP_MSG_RDY flag in the
DP_DEVICE_SERVICE_IRQ_VECTOR DPCD register) may cancel the reply
(clearing DP_DOWN_REP_MSG_RDY and the reply message buffer) after 110
ms, if the reply is not processed by that time.
Avoid MST down-message timeouts described above, by locking the PPS
state for AUX transfers only if this is actually required: on eDP ports,
where the VDD power depends on the PPS state and on all DP and eDP ports
on VLV/CHV, where the PPS is a pipe instance and hence a modeset on any
port possibly affecting the PPS state.
v2: Don't move PPS locking/VDD enabling to a separate function. (Jani)

There are two panel_replay scenarios fbc wa need to be aware of,
panel replay with and without selective update capability.
Panel replay without selective update don't have any fbc wa.
So keep the fbc psr1 wa as it is.
The current fbc psr2 wa is mainly about selective fetch and we
need to apply the fbc wa if selective fetch is on - irrespective
of panel replay. Hence we can't exclude panel replay from the
fbc psr2 wa.
