The mtk_dp driver registers a phy device which is handled by the
phy_mtk_dp driver and assumes that the phy probe will complete
synchronously, proceeding to make use of functionality exposed by that
driver right away. This assumption however is false when the phy driver
is built as a module, causing the mtk_dp driver to fail probe in this
case.
Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to
ensure the phy module has been loaded before the dp, so that the phy
probe happens synchrounously and the mtk_dp driver can probe
successfully even with the phy driver built as a module.

Since commit e89f45edb7 ("ASoC: amd: vangogh: Add check for acp config
flags in vangogh platform"), the Vangogh ACP PCI driver could not be used
anymore for boards which happen to have a matching entry in acp-config
list.
Commit f18818eb0d ("ASoC: amd: vangogh: Add condition check for acp
config flag") slightly changed the behaviour to permit loading the
driver if AMD_LEGACY flag is set. However, for AMD_SOF flag the probing
is still denied, even if SOF support is disabled in kernel
configuration.
While this helps preventing conflicts between SOF and generic ACP
drivers, there are cases where a fallback to the generic non-SOF support
would still be needed or useful, e.g. SOF firmware is not available or
doesn't work properly, SOF driver is broken or doesn't provide full
support for a particular hardware, or simply for testing/debugging the
alternative solution. A real-life example is Steam Deck OLED, which
works with both drivers.
Prevent returning from probe() when ACP config indicates SOF support for
the current board *and* the Vangogh SOF driver is not enabled in kernel
configuration.

The Vangogh machine driver variant based on the MAX98388 amplifier, as
found on Valve's Steam Deck OLED, relies on probing via an ACPI match
table. This worked fine until commit 197b1f7f0d ("ASoC: amd: Add new
dmi entries to config entry") enabled SOF support for the target machine
(i.e. Galileo product), causing the sound card to enter the deferred
probe state indefinitely:
$ cat /sys/kernel/debug/devices_deferred
AMDI8821:00 acp5x_mach: Register card (acp5x-max98388) failed
The issue is related to commit e89f45edb7 ("ASoC: amd: vangogh: Add
check for acp config flags in vangogh platform"), which tries to
mitigate potential conflicts between SOF and generic ACP Vangogh
drivers, due to sharing the PCI device IDs.
However, the solution is effective only if the machine driver is
directly probed by pci-acp5x through platform_device_register_full().
Hence, remove the conflicting ACPI based probing and rely exclusively on
DMI quirks for sound card setup.

This adds a new counter tool to be able to test various watch events.
A flexible watch array can be populated from command line, each field
may be tuned with a dedicated command line sub-option in "--watch" string.
Several watch events can be defined, each can have specific watch options,
by using "--watch <watch 1 options> --watch <watch 2 options>".
Watch options is a comma separated list.
It also comes with a simple default watch (to monitor overflow/underflow
events), used when no watch parameters are provided. It's equivalent to:
counter_watch_events -w comp_count,scope_count,evt_ovf_udf
The print_usage() routine proposes another example, from the command line,
which generates a 2 elements watch array, to monitor:
- overflow underflow events
- capture events, on channel 3, that reads read captured data by
specifying the component id (capture3_component_id being 7 here).

Keep all pipe DMC event handlers disabled until needed (which is never

We can also drop DG2 from disable_all_flip_queue_events() since
on DG2 the pipe DMC is the one that handles the flip queue events.

The recent fix to ignore invalid x2APIC entries inadvertently broke
systems with creative MADT APIC tables. The affected systems have APIC
MADT tables where all entries have invalid APIC IDs (0xFF), which means
they register exactly zero CPUs.
But the condition to ignore the entries of APIC IDs < 255 in the X2APIC
MADT table is solely based on the count of MADT APIC table entries.
As a consequence, the affected machines enumerate no secondary CPUs at
all because the APIC table has entries and therefore the X2APIC table
entries with APIC IDs < 255 are ignored.
Change the condition so that the APIC table preference for APIC IDs <
255 only becomes effective when the APIC table has valid APIC ID
entries.
IOW, an APIC table full of invalid APIC IDs is considered to be empty
which in consequence enables the X2APIC table entries with a APIC ID
< 255 and restores the expected behaviour.
