Until the commit e11f0f90a6 ("ALSA: pcm: remove SNDRV_PCM_IOCTL1_INFO
internal command"), there was a possibility to pass information
about the synchronized streams to the user space. The mentioned
commit removed blindly the appropriate code with an irrelevant comment.
The revert may be appropriate, but since this API was lost for several
years without any complains, it's time to improve it. The hardware
parameters may change the used stream clock source (e.g. USB hardware)
so move this synchronization ID to hw_params as read-only field.
It seems that pipewire can benefit from this API (disable adaptive
resampling for perfectly synchronized PCM streams) now.
Note that the contents of ID is not supposed to be used for direct
comparison with a specific byte sequence. The "empty" case is when
all bytes are zero (driver does not offer this information)
and all other cases must be only used for equal comparison among
PCM streams (including different sound cards) if they are using
identical hardware clock.

As it turns out, there is a large number of out-of-tree DTSes (in
OpenWrt project) that used to specify incorrect (active high) polarity
for the Lantiq reset GPIO, so to keep compatibility while they are
being updated a quirk for force the polarity low is needed. Luckily
these old DTSes used nonstandard name for the property ("gpio-reset" vs
"reset-gpios") so the quirk will not hurt if there are any new devices
that need inverted polarity as they can specify the right polarity in
their DTS when using the standard "reset-gpios" property.
Additionally the condition to enable the transition from standard to
non-standard reset GPIO property name was inverted and the replacement
name for the property was not correct. Fix this as well.

When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.
Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.
/ # cat /proc/interrupts | grep smp2p
18: ... ipcc 196610 Edge smp2p-adsp

In case of all pipe clocks, there is a QMP PHY clock that is feeding them.
If, for whatever reason, the clock from the PHY is not enabled, halt bit
will not get set, and the clock controller driver will assume the clock
is stuck in a specific state. The way this is supposed to be properly
fixed is to defer the checking of the halt bit until after the PHY clock
has been initialized, but doing so complicates the clock controller
driver. In fact, since these pipe clocks are consumed by the PHY, while
the PHY is also the one providing the source, if clock gets stuck, the PHY
driver would be to blame. So instead of checking the halt bit in here,
just skip it and assume the PHY driver is handling the source clock
correctly.

phy_suspend() checks the WoL status, and then dereferences
phydrv->flags if (and only if) we decided that WoL has been enabled
on either the PHY or the netdev.
We then check whether phydrv was NULL, but we've potentially already
dereferenced the pointer.
If phydrv is NULL, then phy_ethtool_get_wol() will return an error
and leave wol.wolopts set to zero. However, if netdev->wol_enabled
is true, then we would dereference a NULL pointer.
Checking the PHY drivers, the only place that phydev->wol_enabled is
checked by them is in their suspend/resume callbacks and nowhere else
(which is correct, because phylib only updates this in phy_suspend()).
So, move the NULL pointer check earlier to avoid a NULL pointer
dereference. Leave the check for phydrv->suspend in place as a driver
may populate the .resume method but not the .suspend method.

On vPro systems, the configuration of the I219-LM to achieve power
gating and S0ix residency is split between the driver and the CSME FW.
It was discovered that in some scenarios, where the network cable is
connected and then disconnected, S0ix residency is not always reached.
This was root-caused to a subset of I219-LM register writes that are not
performed by the CSME FW. Therefore, the driver should perform these
register writes on corporate setups, regardless of the CSME FW state.
This was discovered on Meteor Lake systems; however it is likely to
appear on other platforms as well.

This reverts commit f0f99f3718.
QDU1000 has 7 register regions. The earlier commit 8e2506d012
("dt-bindings: cache: qcom,llcc: Add LLCC compatible for QDU1000/QRU1000")
to add llcc compatible was reflecting the same, but dtsi change for
QDU1000 was not aligning with its binding. Later, commit f0f99f3718
("dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries") was merged
intended to fix this misalignment.
After the LLCC driver refactor, each LLCC bank/channel need to be
represented as one register space to avoid mapping to the region where
access is not there. Hence, revert the commit f0f99f3718 ("dt-bindings:
cache: qcom,llcc: correct QDU1000 reg entries") to align QDU1000 llcc
binding with its dtsi node.
