Add MIPI DSI support for the Renesas RZ/V2H(P) SoC. Compared to the
RZ/G2L family, the RZ/V2H(P) requires dedicated D-PHY PLL programming,
different clock configuration, and additional timing parameter handling.
The driver introduces lookup tables and helpers for D-PHY timings
(TCLK*, THS*, TLPX, and ULPS exit) as specified in the RZ/V2H(P) hardware
manual. ULPS exit timing depends on the LPCLK rate and is now handled
explicitly.
The implementation also adds support for 16 bpp RGB format, updates the
clock setup path to use the RZ/V2H PLL divider limits, and provides new
.dphy_init, .dphy_conf_clks, and .dphy_startup_late_init callbacks to
match the RZ/V2H sequence.
With these changes, the RZ/V2H(P) can operate the MIPI DSI interface in
compliance with its hardware specification while retaining support for
existing RZ/G2L platforms.

aie_destroy_context() is invoked during error handling in
aie2_create_context(). However, aie_destroy_context() assumes that the
context's mailbox channel pointer is non-NULL. If mailbox channel
creation fails, the pointer remains NULL and calling aie_destroy_context()
can lead to a NULL pointer dereference.
In aie2_create_context(), replace aie_destroy_context() with a function
which request firmware to remove the context created previously.

accel/amdxdna: Fix race where send ring appears full due to delayed head update
The firmware sends a response and interrupts the driver before advancing
the mailbox send ring head pointer. As a result, the driver may observe
the response and attempt to send a new request before the firmware has
updated the head pointer. In this window, the send ring still appears
full, causing the driver to incorrectly fail the send operation.
This race can be triggered more easily in a multithreaded environment,
leading to unexpected and spurious "send ring full" failures.
To address this, poll the send ring head pointer for up to 100us before
returning a full-ring condition. This allows the firmware time to update
the head pointer.

perf/x86/intel: Fix NULL event dereference crash in handle_pmi_common()
handle_pmi_common() may observe an active bit set in cpuc->active_mask
while the corresponding cpuc->events[] entry has already been cleared,
which leads to a NULL pointer dereference.
This can happen when interrupt throttling stops all events in a group
while PEBS processing is still in progress. perf_event_overflow() can
trigger perf_event_throttle_group(), which stops the group and clears
the cpuc->events[] entry, but the active bit may still be set when
handle_pmi_common() iterates over the events.
The following recent fix:
7e772a93eb61 ("perf/x86: Fix NULL event access and potential PEBS record loss")
moved the cpuc->events[] clearing from x86_pmu_stop() to x86_pmu_del() and
relied on cpuc->active_mask/pebs_enabled checks. However,
handle_pmi_common() can still encounter a NULL cpuc->events[] entry
despite the active bit being set.
Add an explicit NULL check on the event pointer before using it,
to cover this legitimate scenario and avoid the NULL dereference crash.

drm/bridge: ti-sn65dsi83: protect device resources on unplug
To support hot-unplug of this bridge we need to protect access to device
resources in case sn65dsi83_remove() happens concurrently to other code.
Some care is needed for the case when the unplug happens before
sn65dsi83_atomic_disable() has a chance to enter the critical section
(i.e. a successful drm_bridge_enter() call), which occurs whenever the
hardware is removed while the display is active. When that happens,
sn65dsi83_atomic_disable() in unable to release the resources taken by
sn65dsi83_atomic_pre_enable().
To ensure those resources are released exactly once on device removal:
* move the code to release them to a dedicated function
* register that function when the resources are taken in
sn65dsi83_atomic_pre_enable()
* if sn65dsi83_atomic_disable() happens before sn65dsi83_remove()
(typical non-hot-unplug case):
* sn65dsi83_atomic_disable() can enter the critical section
(drm_bridge_enter() returns 0) -> it releases and executes the
devres action
* if sn65dsi83_atomic_disable() happens after sn65dsi83_remove()
(typical hot-unplug case):
* sn65dsi83_remove() -> drm_bridge_unplug() prevents
sn65dsi83_atomic_disable() from entering the critical section
(drm_bridge_enter() returns nonzero), so sn65dsi83_atomic_disable()
cannot release and execute the devres action
* the devres action is executed at the end of sn65dsi83_remove()

to mark a critical section that should not be entered after that.
This is inspired by the drm_dev_unplugged/enter/exit() functions for struct

When CONFIG_PM and CONFIG_PM_SLEEP are unset, SET_SYSTEM_SLEEP_PM_OPS()
and SET_RUNTIME_PM_OPS() evaluate to nothing, so these functions appear
unused to the compiler in this configuration.
Use the modern SYSTEM_SLEEP_PM_OPS and RUNTIME_PM_OPS macros to resolve
these warnings, which is what they are intended to do. Additionally,
wrap &cix_ipbloq_hda_pm in pm_ptr() to ensure the compiler can drop the
entire structure when CONFIG_PM is unset.
