Currently, some of the USB4 clocks/resets are described, but not all
of the back-end muxes are present. Configuring them properly is
necessary for proper operation of the hardware.
Add all the resets & muxes and wire up any unaccounted USB4 clock paths.

Prevent enabling panel replay if the sink doesn't support this due to
DSC being enabled.
Panel replay has two modes, updating full frames or only selected
regions of the frame. If the sink doesn't support Panel Replay in full
frame update mode with DSC prevent Panel Replay completely if DSC is
enabled. If the sink doesn't support Panel Replay only in the selective
update mode while DSC is enabled, it will still support Panel Replay in
the full frame update mode, so only prevent selective updates in this
case.
v2:
- Use Panel Replay instead of PR in debug prints. (Jouni)
- Rebase on change tracking the link DSC state in the crtc state.

The state of all the CRTCs on an MST link must be recomputed, if DSC
gets enabled on any of the CRTCs on the link. For instance an MST
docking station's Panel Replay capability may depend on whether DSC is
enabled on any of the dock's streams (aka CRTCs). To assist the Panel
Replay state computation for a CRTC based on the above, track in the
CRTC state if DSC is enabled on any CRTC on an MST link.
The intel_link_bw_limits::force_fec_pipes mask is used for a reason
similar to the above: enable FEC on all CRTCs of a non-UHBR (8b10b) MST
link if DSC is enabled on any of the link's CRTCs. The FEC enabled state
for a CRTC doesn't indicate if DSC is enabled on a UHBR MST link (FEC is
always enabled by the HW for UHBR, hence it's not tracked by the
intel_crtc_state::fec_enable flag for such links, where this flag is
always false).
Based on the above, to be able to determine the DSC state on both
non-UHBR and UHBR MST links, track the more generic DSC-enabled-on-link
state (instead of the FEC-enabled-on-link state) for each CRTC in
intel_link_bw_limits.

Track whether DSC is enabled on any CRTC on a link. On DP-SST (and DSI)
this will always match the CRTC's DSC state, those links having only a
single stream (aka CRTC). For instance, on DP-MST if DSC is enabled for
CRTC#0, but disabled for CRTC#1, the DSC/FEC state for these CRTCs will
be as follows:
CRTC#0:
- compression_enable = true
- compression_enabled_on_link = true
- fec_enable = true for 8b10b, false for 128b132b
CRTC#1:
- compression_enable = false
- compression_enabled_on_link = true
- fec_enable = true for 8b10b, false for 128b132b
This patch only sets compression_enabled_on_link for CRTC#0 above and
enables FEC on CRTC#0 if DSC was enabled on any other CRTC on the 8b10b
MST link. A follow-up change will make sure that the state of all the
CRTCs (CRTC#1 above) on an MST link is recomputed if DSC gets enabled on
any CRTC, setting compression_enabled_on_link and fec_enable for these.

Export the helper function to determine if FEC is required on a non-UHBR
(8b10b) SST or MST link. A follow up change will take this into use for
MST as well.
While at it determine the output type from the CRTC state, which allows
dropping the intel_dp argument. Also make the function return the
required FEC state, instead of setting this in the CRTC state, which
allows only querying this requirement, without changing the state.
Also rename the function to intel_dp_needs_8b10b_fec(), to clarify that
the function determines if FEC is required on an 8b10b link (on 128b132b
links FEC is always enabled by the HW implicitly, so the function will
return false for that case).

Atm, in the DP SST case the FEC state is computed before
intel_crtc_state::port_clock is initialized, hence intel_dp_is_uhbr()
will always return false and the FEC state will be always computed
assuming a non-UHBR link.
This happens to work, since the FEC state is recomputed later in
intel_dp_mtp_tu_compute_config(), where port_clock will be set already,
so intel_crtc_state::fec_enable will be reset as expected for UHBR. This
also depends on link rates being tried in an increasing order (i.e. from
non-UHBR -> UHBR link rates) in dsc_compute_link_config(), thus
intel_crtc_state::fec_enable being set for the non-UHBR rates and
getting reset for the first UHBR rate as expected.
A follow-up change will reuse intel_dp_fec_compute_config() for the DP
MST state computation, prepare for that here, making sure that the
function determines the correct intel_crtc_state::fec_enable=false state
for UHBR link rates based on the above.
The DP SST and MST state computation should be further unified to avoid
computing/setting the intel_crtc_state::fec_enable state multiple times,
but that's left for a follow-up change. For now add only code comments
about this.

Add a helper to enable the DSC compression configuration for a CRTC.
Follow-up changes will introduce tracking for the same DSC state on the
whole link, which will need to be set whenever DSC is enabled for the
CRTC. Also, according to the above, when querying the DSC state on the
link, both the CRTC's and the link's DSC state must be considered.
Setting the DSC configuration for a CRTC and querying the DSC
configuration for the link (added by follow-up changes) is better done
via helper functions based on the above, prepare for that here.

The same suspend and resume callbacks are used for both suspend-to-RAM/idle
and hibernation. These callbacks invoke pm_suspend_via_firmware() and
pm_resume_via_firmware(), respectively. In the .freeze() of hibernation,
pm_suspend_via_firmware() returns false, causing the driver to put ISH into
D0i3. However, during the .thaw(), pm_resume_via_firmware() returns true,
leading the driver to treat ISH as resuming from D3 instead of D0i3. The
asymmetric behavior between .freeze() and .thaw() during hibernation can
cause the client connection states on the firmware side and the driver side
to become inconsistent.
To address the inconsistent client connection states issue, separate
hibernate-related callbacks (freeze, thaw) in dev_pm_ops. Since ISH does
not need to save any firmware-related state when entering hibernation, it
is sufficient to call pci_save_state() in .freeze() to prevent the PCI bus
from changing the ISH power state. No actions are required in .thaw().

On ISH power-up, the bootloader enters sleep after preparing to load the
main firmware, waiting for the driver to be ready. When the driver is
ready, it sends a void message to wake up the bootloader and load the main
firmware. The main firmware then sends MNG_RESET_NOTIFY to the driver for
handshake.
This void message-based IPC handshake only works if the main firmware has
not been loaded. During hibernation resume, if the restore kernel has the
ISH driver, the driver wakes up the bootloader to load the main firmware
and perform IPC handshake. However, when switching to the image kernel,
since the main firmware is already loaded, sending a void message in the
.restore() callback does not trigger IPC handshake.
By sending MNG_RESET_NOTIFY (IPC RESET message) in ish_wakeup() instead of
a void message, we can explicitly wake up the bootloader and perform IPC
handshake, regardless of the firmware state. Additionally, since
ish_ipc_reset() already waits for recvd_hw_ready, the redundant wait for
recvd_hw_ready in ish_hw_start() is removed.
The timeout for waiting for HW ready is set to 10 seconds, matching the
original timeout value used in ish_wakeup(), to ensure reliable wakeup on
hardware that requires more time, such as the Lenovo ThinkPad X1 Titanium
Gen 1.

Both ISH firmware and driver can actively send MNG_RESET_NOTIFY to initiate
an FW reset handshake. Upon receiving this, the peer should reply with
MNG_RESET_NOTIFY_ACK. Therefore, the driver should schedule the FW reset
handshake work function when receiving either MNG_RESET_NOTIFY or
MNG_RESET_NOTIFY_ACK.
Previously, driver only scheduled the work function on MNG_RESET_NOTIFY.
This patch ensures the work function is scheduled on both messages, but
only replies with MNG_RESET_NOTIFY_ACK when receiving MNG_RESET_NOTIFY.

When ISH resumes from D3, the connection between ishtp clients and firmware
is lost. The ish_resume() function schedules resume_work asynchronously to
re-initiate the connection and then returns immediately. This can cause a
race where the upper-layer ishtp client driver's .resume() may execute
before the connection is fully restored, leaving the client in a stale
connected state. If the client sends messages during this window, the
firmware cannot respond.
To avoid this, reset the ishtp clients' state before returning from
ish_resume() if ISH is resuming from D3.

When resuming from suspend-to-RAM or hibernate, the ISH firmware is powered
on from D3, causing all previous client connections between the firmware
and driver to be lost. Although the underlying ishtp bus driver initiates a
client reconnection flow, this process is asynchronous. As a result, when
hid_ishtp_cl_resume_handler() is executed, the connection may not have been
re-established yet. Clearing the suspended flag prematurely in this
scenario can lead to a timeout when the upper-layer HID sensor driver set
feature during resume.
To prevent such timeouts, only clear the suspended flag after confirming
that the connection state is ISHTP_CL_CONNECTED.

During suspend/resume tests with S2IDLE, some ISH functional failures were
observed because of delay in executing ISH resume handler. Here
schedule_work() is used from resume handler to do actual work.
schedule_work() uses system_wq, which is a per CPU work queue. Although
the queuing is not bound to a CPU, but it prefers local CPU of the caller,
unless prohibited.
Users of this work queue are not supposed to queue long running work.
But in practice, there are scenarios where long running work items are
queued on other unbound workqueues, occupying the CPU. As a result, the
ISH resume handler may not get a chance to execute in a timely manner.
In one scenario, one of the ish_resume_handler() executions was delayed
nearly 1 second because another work item on an unbound workqueue occupied
the same CPU. This delay causes ISH functionality failures.
A similar issue was previously observed where the ISH HID driver timed out
while getting the HID descriptor during S4 resume in the recovery kernel,
likely caused by the same workqueue contention problem.
Create dedicated unbound workqueues for all ISH operations to allow work
items to execute on any available CPU, eliminating CPU-specific bottlenecks
and improving resume reliability under varying system loads. Also ISH has
three different components, a bus driver which implements ISH protocols, a
PCI interface layer and HID interface. Use one dedicated work queue for all
of them.

Attribute access is now serialized in the hardware monitoring core,
so locking in the driver code is no longer necessary. Drop it.

commit 337bf13aa9dda ("PCI/VGA: Replace vga_is_firmware_default() with a
screen info check") introduced an implicit dependency upon SCREEN_INFO by
removing the open coded implementation.
If a user didn't have CONFIG_SCREEN_INFO set, vga_is_firmware_default()
would now return false. SCREEN_INFO is only used on X86 so add a
conditional select for SCREEN_INFO to ensure that the VGA arbiter works as
intended.

Since commit 54f45a30c0d0 ("PCI/MSI: Add startup/shutdown for per
device domains") set callback irq_startup() and irq_shutdown() of
the struct pci_msi[x]_template, __irq_startup() will always invokes
irq_startup() callback instead of irq_enable() callback overridden
in vmd_init_dev_msi_info(). This will not start the IRQ correctly.
Also override irq_startup()/irq_shutdown() in vmd_init_dev_msi_info(),
so the irq_startup() can invoke the real logic.

The "_probe" suffix of the driver structure name prevents modpost from
warning about section mismatches so replace it to catch any future
issues like the recently fixed probe function being incorrectly marked
as __init.

is down
If the interface is down, the CAN controller might be powered down, the
clock disabled, and/or it's external reset asserted.
Don't wake up the controller to read the CAN bus error counters, if the
interface is down.

devm_kzalloc() fails
If devm_kzalloc() fails, it already outputs an error message. Remove the
error message from m_can_class_register() accordingly.
