The two alarm LEDs of on the uDPU board are stopped working since
commit 78efa53e71 ("leds: Init leds class earlier").
The LEDs are driven by the GPIO{15,16} pins of the North Bridge
GPIO controller. These pins are part of the 'spi_quad' pin group
for which the 'spi' function is selected via the default pinctrl
state of the 'spi' node. This is wrong however, since in order to
allow controlling the LEDs, the pins should use the 'gpio' function.
Before the commit mentined above, the 'spi' function is selected
first by the pinctrl core before probing the spi driver, but then
it gets overridden to 'gpio' implicitly via the
devm_gpiod_get_index_optional() call from the 'leds-gpio' driver.
After the commit, the LED subsystem gets initialized before the
SPI subsystem, so the function of the pin group remains 'spi'
which in turn prevents controlling of the LEDs.
Despite the change of the initialization order, the root cause is
that the pinctrl state definition is wrong since its initial commit
0d45062cfc ("arm64: dts: marvell: Add device tree for uDPU board"),
To fix the problem, override the function in the 'spi_quad_pins'
node to 'gpio' and move the pinctrl state definition from the
'spi' node into the 'leds' node.

Due to sinks like ETR and ETB don't support interrupt handling, the
hardware trace data might be lost for continuous running tasks.
This commit takes advantage of the AUX pause for updating trace buffer
to mitigate the trace data losing issue.
The per CPU sink has its own interrupt handling. Thus, there will be a
race condition between the updating buffer in NMI and sink's interrupt
handler. To avoid the race condition, this commit disallows updating
buffer on AUX pause for the per CPU sink. Currently, this is only
applied for TRBE.

The buffer update callbacks disable the sink before syncing data but
misses to re-enable it afterward. This is fine in the general flow,
because the sink will be re-enabled the next time the PMU event is
activated.
However, during AUX pause and resume, if the sink is disabled in the
buffer update callback, there is no chance to re-enable it when AUX
resumes.
To address this, the callbacks now check the event state
'event->hw.state'. If the event is an active state (0), the sink is
re-enabled.
For the TMC ETR driver, buffer updates are not fully protected by
the driver's spinlock. In this case, the sink is not re-enabled if its
reference counter is 0, in order to avoid race conditions where the sink
may have been completely disabled.

This commit supports AUX trace pause and resume in a perf session for
Arm CoreSight.
First, we need to decide which flag can indicate the CoreSight PMU event
has started. The 'event->hw.state' cannot be used for this purpose
because its initial value and the value after hardware trace enabling
are both 0.
On the other hand, the context value 'ctxt->event_data' stores the ETM
private info. This pointer is valid only when the PMU event has been
enabled. It is safe to permit AUX trace pause and resume operations only
when it is not a NULL pointer.
To achieve fine-grained control of the pause and resume, only the tracer
is disabled and enabled. This avoids the unnecessary complexity and
latency caused by manipulating the entire link path.

Add support for the Exynos USB 3.2 DRD 4nm controller. It's used in
recent 4nm SoCs like Exynos2200 and Exynos2400.
This device consists of 3 underlying and independent phys: SEC link
control phy, Synopsys eUSB 2.0 and Synopsys USBDP/SS combophy. Unlike
older device designs, where the internal phy blocks were all IP of
Samsung, Synopsys phys are present. This means that the link controller
is now mapped differently to account for missing bits and registers.
The Synopsys phys also have separate register bases.
As there are non-SEC PHYs present now, it doesn't make much sense to
implement them in this driver. They are expected to be configured
by external drivers, so pass phandles to them. USBDRD3.2 link controller
set up is still required beforehand.

The current device MSI infrastructure is subtly broken, as it will issue an
.msi_prepare() callback into the MSI controller driver every time it needs
to allocate an MSI. That's pretty wrong, as the contract (or unwarranted
assumption, depending who you ask) between the MSI controller and the core
code is that .msi_prepare() is called exactly once per device.
This leads to some subtle breakage in some MSI controller drivers, as it
gives the impression that there are multiple endpoints sharing a bus
identifier (RID in PCI parlance, DID for GICv3+). It implies that whatever
allocation the ITS driver (for example) has done on behalf of these devices
cannot be undone, as there is no way to track the shared state. This is
particularly bad for wire-MSI devices, for which .msi_prepare() is called
for each input line.
To address this issue, move the call to .msi_prepare() to take place at the
point of irq domain allocation, which is the only place that makes
sense. The msi_alloc_info_t structure is made part of the
msi_domain_template, so that its life-cycle is that of the domain as well.
Finally, the msi_info::alloc_data field is made to point at this allocation
tracking structure, ensuring that it is carried around the block.
This is all pretty straightforward, except for the non-device-MSI
leftovers, which still have to call .msi_prepare() at the old spot. One
day...

The ITS driver currently nukes the structure representing an endpoint
device translating via an ITS on freeing the last LPI allocated for it.
That's an unfortunate state of affair, as it is pretty common for a driver
to allocate a single MSI, do something clever, teardown this MSI, and
reallocate a whole bunch of them. The NVME driver does exactly that,
amongst others.
What happens in that case is that the core code is accidentaly issuing
another .msi_prepare() call, even if it shouldn't. This luckily cancels
the above behaviour and hides the problem.
In order to fix the core code, start by implementing the new
.msi_teardown() callback. Nothing calls it yet, so a side effect is that
the its_dev structure will not be freed and that the DID will stay
mapped. Not a big deal, and this will be solved in following patches.

When mhi_async_power_up() enables IRQs, it is possible that we could
receive a SYSERR notification from the device if the firmware has crashed
for some reason. Then the SYSERR notification queues a work item that
cannot execute until the pm_mutex is released by mhi_async_power_up().
So the SYSERR work item will be pending. If mhi_async_power_up() detects
the SYSERR, it will handle it. If the device is in PBL, then the PBL state
transition event will be queued, resulting in a work item after the
pending SYSERR work item. Once mhi_async_power_up() releases the pm_mutex,
the SYSERR work item can run. It will blindly attempt to reset the MHI
state machine, which is the recovery action for SYSERR. PBL/SBL are not
interrupt driven and will ignore the MHI Reset unless SYSERR is actively
advertised. This will cause the SYSERR work item to timeout waiting for
reset to be cleared, and will leave the host state in SYSERR processing.
The PBL transition work item will then run, and immediately fail because
SYSERR processing is not a valid state for PBL transition.
This leaves the device uninitialized.
This issue has a fairly unique signature in the kernel log:
mhi mhi3: Requested to power ON
Qualcomm Cloud AI 100 0000:36:00.0: Fatal error received from
device. Attempting to recover
mhi mhi3: Power on setup success
mhi mhi3: Device failed to exit MHI Reset state
mhi mhi3: Device MHI is not in valid state
We cannot remove the SYSERR handling from mhi_async_power_up() because the
device may be in the SYSERR state, but we missed the notification as the
irq was fired before irqs were enabled. We also can't queue the SYSERR work
item from mhi_async_power_up() if SYSERR is detected because that may
result in a duplicate work item, and cause the same issue since the
duplicate item will blindly issue MHI reset even if SYSERR is no longer
active.
Instead, add a check in the SYSERR work item to make sure that MHI reset is
only issued if the device is in SYSERR state for PBL or SBL EEs.

The ticket TKT0676370 shows the description of TX_VBOOST_LVL is wrong in
register PHY_CTRL3 bit[31:29].
011: Corresponds to a launch amplitude of 1.12 V.
010: Corresponds to a launch amplitude of 1.04 V.
000: Corresponds to a launch amplitude of 0.88 V.
After updated:
011: Corresponds to a launch amplitude of 0.844 V.
100: Corresponds to a launch amplitude of 1.008 V.
101: Corresponds to a launch amplitude of 1.156 V.
This will correct it accordingly.

The function snd_es1968_capture_open() calls the function
snd_pcm_hw_constraint_pow2(), but does not check its return
value. A proper implementation can be found in snd_cx25821_pcm_open().
Add error handling for snd_pcm_hw_constraint_pow2() and propagate its
error code.

With the settings used in the commit 9c56a1de29 ("phy: qcom-qusb2: add
QUSB2 support for IPQ5424"), compliance test cases especially
eye-diagram (Host High-speed Signal Quality) tests are failing.
Reuse the IPQ6018 settings for IPQ5424 as mentioned in the Hardware
Design Document which helps to meet all the complaince requirement test
cases.

With the current settings, compliance tests especially eye diagram
(Host High-speed Signal Quality) tests are failing. Reuse the IPQ6018
settings to overcome this issue, as mentioned in the Hardware Design
Document.
So revert the change which introduced the new settings and reuse the
IPQ6018 settings in the subsequent patch.

Commit 8589e325ba ("genirq/manage: Rework irq_set_irq_wake()") updated
the irq_set_irq_wake() to use the new guards for locking the interrupt
descriptor.
However, in doing so it inadvertently changed irq_set_irq_wake() such that
the 'chip_bus_lock' is no longer acquired. This has caused system suspend
tests to fail on some Tegra platforms.
Fix this by correcting the guard used in irq_set_irq_wake() to ensure the
'chip_bus_lock' is held.
