Only vcn0 can process AV1 codecx. In order to use both vcn0 and
vcn1 in h264/265 transcode to AV1 cases, set vcn0 sched score to 1
at initialization time.

The buffer object backing the fbdev emulation got pinned twice: by the
fb_probe helper radeon_fbdev_create_pinned_object() and the modesetting
code when the framebuffer got displayed. It only got unpinned once by
the fbdev helper radeon_fbdev_destroy_pinned_object(). Hence TTM's BO-
release function complains about the pin counter. Forcing the outputs
off also undoes the modesettings pin increment.

The VBIOS image update flow requires userspace to:
1) Write the image to `psp_vbflash`
2) Read `psp_vbflash`
3) Poll `psp_vbflash_status` to check for completion
If userspace reads `psp_vbflash` before writing an image, it's
possible that it causes problems that can put the dGPU into an invalid
state.
Explicitly check that an image has been written before letting a read
succeed.

When MEC executes unmap_queue for mid command buffer preemption, it will
kick the write pointer of the gfx ring, set CP_VMID_PREEMPT to trigger the
preemption and wait for CP_VMID_PREEMPT becomes zero after the preemption
done. There is a race condition that PFP may excute the resetting command
before MEC set CP_VMID_PREEMPT. As a result, hang happens as
CP_VMID_PREEMPT is always 0xffff.
To avoid this, we send resetting CP_VMID_PREEMPT command after the trailing
fence is siganled and update gfx write pointer explicitly.

Export Passive version 2 table similar to the way _TRT and _ART tables
via IOCTLs.
This removes need for binary utility to read ACPI Passive 2 table by
providing open source support. This table already has open source
implementation in the user space thermald, when the table is part of
data vault exported by the int3400 sysfs.
This table is supported in some older platforms before Ice Lake
generation.
Passive 2 tables contain multiple entries. Each entry has following
fields:
* Source: Named Reference (String). This is the source device for
temperature.
* Target: Named Reference (String). This is the target device to
control.
* Priority: Priority of this device compared to others.
* SamplingPeriod: Time Period in 1/10 of seconds unit.
* PassiveTemp: Passive Temperature in 1/10 of Kelvin.
* SourceDomain: Domain for the source (00:Processor, others reserved).
* ControlKnob: Type of control knob (00:Power Limit 1, others: reserved)
* Limit: The target state to set on reaching passive temperature.
This can be a string "max", "min" or a power limit value.
* LimitStepSize: Step size during activation.
* UnLimitStepSize: Step size during deactivation.
* Reserved1: Reserved
Three IOCTLs are added similar to IOCTLs for reading TRT:
ACPI_THERMAL_GET_PSVT_COUNT: Number of passive 2 entries.
ACPI_THERMAL_GET_PSVT_LEN: Total return data size (count x each
passive 2 entry size).
ACPI_THERMAL_GET_PSVT: Get the data as an array of objects with
passive 2 entries.

When using dm-verity with a data partition on an emmc device, dm-verity
races with the initialization of the (e)MMC/SD cards. This is because the
card detection procedure is being managed from a workqueue, rather than
synchronously from the mmc host's ->probe() routine.
To allow the card detect to be synchronous, let's simply skip using the
workqueue at the first initialization attempt from mmc_start_host().

Add support for TPS65219 PMICs GPIO interface.
3 GPIO pins:
- GPIO0 only is IO but input mode reserved for MULTI_DEVICE_ENABLE usage.
- GPIO1 and GPIO2 are Output only and referred as GPO1 and GPO2 in spec.
GPIO0 is statically configured as input or output prior to Linux boot.
it is used for MULTI_DEVICE_ENABLE function.
This setting is statically configured by NVM.
GPIO0 can't be used as a generic GPIO (specification Table 8-34).
It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1.
Datasheet describes specific usage for non standard GPIO.

`_regmap_update_bits()` checks if the current register value differs
from the new value, and only writes to the register if they differ. When
testing hardware drivers, it might be desirable to always force a
register write, for example when writing to a `regmap_field`. This
enables and simplifies testing and verification of the hardware
interaction. For example, when using a hardware mock/simulation model,
one can then more easily verify that the driver makes the correct
expected register writes during certain events.
Add a bool variable `force_write_field` and a corresponding debugfs
entry to enable this. Since this feature could interfere with driver
operation, guard it with a macro.

regcache_maple_sync() tries to sync all cached values no matter
whether it's writable or not. OTOH, regache_sync_val() does care the
wrtability and returns -EIO for a read-only register. This results in
an error message like:
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2f0009. -5
and the sync loop is aborted incompletely.
This patch adds the writable register check to regcache_sync_val() for
addressing the bug above.
Note that, although we may add the check in the caller side
(regcache_maple_sync()), here we put in regcache_sync_val(), so that a
similar case like this can be avoided in future.

LS1028A is using DMA with LPUART. Having RX watermark set to 1, means
DMA transactions are started only after receiving the second character.
On other platforms with newer LPUART IP, Receiver Idle Empty function
initiates the DMA request after the receiver is idling for 4 characters.
But this feature is missing on LS1028A, which is causing a 1-character
delay in the RX direction on this platform.
Set RX watermark to 0 to initiate RX DMA after each character.

The call site of nouveau_dsm_pci_probe() uses single set of output
variables for all invocations. So, we must not write anything to them
unless it's an NVIDIA device. Otherwise, if we are called with another
device after the NVIDIA device, we'll clober the result of the NVIDIA
device.
For example, if the other device doesn't have _PR3 resources, the
detection later would miss the presence of power resource support, and
the rest of the code will keep using Optimus DSM, breaking power
management for that machine.
Also, because we're detecting NVIDIA's DSM, it doesn't make sense to run
this detection on a non-NVIDIA device anyway. Thus, check at the
beginning of the detection code if this is an NVIDIA card, and just
return if it isn't.
This, together with commit d22915d22ded ("drm/nouveau/devinit/tu102-:
wait for GFW_BOOT_PROGRESS == COMPLETED") developed independently and
landed earlier, fixes runtime power management of the NVIDIA card in
Lenovo Legion 5-15ARH05. Without this patch, the GPU resumption code
will "timeout", sometimes hanging userspace.
As a bonus, we'll also stop preventing _PR3 usage from the bridge for
unrelated devices, which is always nice, I guess.

usb_udc_connect_control(), soft_connect_store() and
usb_gadget_deactivate() can potentially race against each other to invoke
usb_gadget_connect()/usb_gadget_disconnect(). To prevent this, guard
udc->started, gadget->allow_connect, gadget->deactivate and
gadget->connect with connect_lock so that ->pullup() is only invoked when
the gadget is bound, started and not deactivated. The routines
usb_gadget_connect_locked(), usb_gadget_disconnect_locked(),
usb_udc_connect_control_locked(), usb_gadget_udc_start_locked(),
usb_gadget_udc_stop_locked() are called with this lock held.

usb_udc_vbus_handler() can be invoked from interrupt context by irq
handlers of the gadget drivers, however, usb_udc_connect_control() has
to run in non-atomic context due to the following:
a. Some of the gadget driver implementations expect the ->pullup
callback to be invoked in non-atomic context.
b. usb_gadget_disconnect() acquires udc_lock which is a mutex.
Hence offload invocation of usb_udc_connect_control()
to workqueue.
UDC should not be pulled up unless gadget driver is bound. The new flag
"allow_connect" is now set by gadget_bind_driver() and cleared by
gadget_unbind_driver(). This prevents work item to pull up the gadget
even if queued when the gadget driver is already unbound.

Some dwc3 glue drivers are currently accessing the driver data of the
child core device directly, which is clearly a bad idea as the child may
not have probed yet or may have been unbound from its driver.
As a workaround until the glue drivers have been fixed, clear the driver
data pointer before allowing the glue parent device to runtime suspend
to prevent its driver from accessing data that has been freed during
unbind.

The Qualcomm dwc3 glue driver is currently accessing the driver data of
the child core device during suspend and on wakeup interrupts. This is
clearly a bad idea as the child may not have probed yet or could have
been unbound from its driver.
The first such layering violation was part of the initial version of the
driver, but this was later made worse when the hack that accesses the
driver data of the grand child xhci device to configure the wakeup
interrupts was added.
Fixing this properly is not that easily done, so add a sanity check to
make sure that the child driver data is non-NULL before dereferencing it
for now.
Note that this relies on subtleties like the fact that driver core is
making sure that the parent is not suspended while the child is probing.

Consider a scenario where cable disconnect happens when there is an active
usb reqest queued to the UDC. As part of the disconnect we would issue an
end transfer with no interrupt-on-completion before giving back this
request. Since we are giving back the request without skipping TRBs the
num_trbs field of dwc3_request still holds the stale value previously used.
Function drivers re-use same request for a given bind-unbind session and
hence their dwc3_request context gets preserved across cable
disconnect/connect. When such a request gets re-queued after cable connect,
we would increase the num_trbs field on top of the previous stale value
thus incorrectly representing the number of TRBs used. Fix this by
resetting num_trbs field before giving back the request.

Currently {modprobe, bind} after {rmmod, unbind} results in probe failure.
genirq: Flags mismatch irq 22. 00000004 (85070400.usb3drd) vs. 00000004 (85070400.usb3drd)
renesas_usb3: probe of 85070000.usb3peri failed with error -16
The reason is, it is trying to register an interrupt handler for the same
IRQ twice. The devm_request_irq() was called with the parent device.
So the interrupt handler won't be unregistered when the usb3-peri device
is unbound.
Fix this issue by replacing "parent dev"->"dev" as the irq resource
is managed by this driver.
