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"

For paired jobs, have the fragment job take a reference on the
geometry job, so that the geometry job cannot be freed until
the fragment job has finished with it.
The geometry job structure is accessed when the fragment job is being
prepared by the GPU scheduler. Taking the reference prevents the
geometry job being freed until the fragment job no longer requires it.

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)
v3: Remove a redundant check and reset vrr.in_range to false. (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.

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.

Existing DPCD access functions return an error code or the number of
bytes being read / write in case of partial access. However a lot of
drivers either (incorrectly) ignore partial access or mishandle error
codes. In other cases this results in a boilerplate code which compares
returned value with the size.
Implement new set of DPCD access helpers, which ignore partial access,
always return 0 or an error code.

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)

The mediatek display driver fails to probe on mt8173-elm-hana and
mt8183-kukui-jacuzzi-juniper-sku16 in v6.14-rc4 due to missing PHY
configurations.
Enable the following PHY drivers for MediaTek platforms:
- CONFIG_PHY_MTK_HDMI=y for HDMI display
- CONFIG_PHY_MTK_MIPI_DSI=y for DSI display

Some SKUs of Xe2_HPD platforms (such as BMG) have GDDR memory type
with ECC enabled. We need to identify this scenario and add a new
case in xelpdp_get_dram_info() to handle it. In addition, the
derating value needs to be adjusted accordingly to compensate for
the limited bandwidth.
