The existing code moves VF to the same namespace as the synthetic NIC
during netvsc_register_vf(). But, if the synthetic device is moved to a
new namespace after the VF registration, the VF won't be moved together.
To make the behavior more consistent, add a namespace check for synthetic
NIC's NETDEV_REGISTER event (generated during its move), and move the VF
if it is not in the same namespace.

The well-known errata regarding EEE not being functional on various KSZ
switches has been refactored a few times. Recently the refactoring has
excluded several switches that the errata should also apply to.
Disable EEE for additional switches with this errata and provide
additional comments referring to the public errata document.
The original workaround for the errata was applied with a register
write to manually disable the EEE feature in MMD 7:60 which was being
applied for KSZ9477/KSZ9897/KSZ9567 switch ID's.
Then came commit 26dd2974c5b5 ("net: phy: micrel: Move KSZ9477 errata
fixes to PHY driver") and commit 6068e6d7ba50 ("net: dsa: microchip:
remove KSZ9477 PHY errata handling") which moved the errata from the
switch driver to the PHY driver but only for PHY_ID_KSZ9477 (PHY ID)
however that PHY code was dead code because an entry was never added
for PHY_ID_KSZ9477 via MODULE_DEVICE_TABLE.
This was apparently realized much later and commit 54a4e5c16382 ("net:
phy: micrel: add Microchip KSZ 9477 to the device table") added the
PHY_ID_KSZ9477 to the PHY driver but as the errata was only being
applied to PHY_ID_KSZ9477 it's not completely clear what switches
that relates to.
Later commit 6149db4997f5 ("net: phy: micrel: fix KSZ9477 PHY issues
after suspend/resume") breaks this again for all but KSZ9897 by only
applying the errata for that PHY ID.
Following that this was affected with commit 08c6d8bae48c("net: phy:
Provide Module 4 KSZ9477 errata (DS80000754C)") which removes
the blatant register write to MMD 7:60 and replaces it by
setting phydev->eee_broken_modes = -1 so that the generic phy-c45 code
disables EEE but this is only done for the KSZ9477_CHIP_ID (Switch ID).
Lastly commit 0411f73c13af ("net: dsa: microchip: disable EEE for
KSZ8567/KSZ9567/KSZ9896/KSZ9897.") adds some additional switches
that were missing to the errata due to the previous changes.
This commit adds an additional set of switches.

When ata_qc_complete() schedules a command for EH using
ata_qc_schedule_eh(), blk_abort_request() will be called, which leads to
req->q->mq_ops->timeout() / scsi_timeout() being called.
scsi_timeout(), if the LLDD has no abort handler (libata has no abort
handler), will set host byte to DID_TIME_OUT, and then call
scsi_eh_scmd_add() to add the command to EH.
Thus, when commands first enter libata's EH strategy_handler, all the
commands that have been added to EH will have DID_TIME_OUT set.
Commit e5dd410acb34 ("ata: libata: Clear DID_TIME_OUT for ATA PT commands
with sense data") clears this bogus DID_TIME_OUT flag for all commands
that reached libata's EH strategy_handler.
libata has its own flag (AC_ERR_TIMEOUT), that it sets for commands that
have not received a completion at the time of entering EH.
ata_eh_worth_retry() has no special handling for AC_ERR_TIMEOUT, so by
default timed out commands will get flag ATA_QCFLAG_RETRY set, and will be
retried after the port has been reset (ata_eh_link_autopsy() always
triggers a port reset if any command has AC_ERR_TIMEOUT set).
For a command that has ATA_QCFLAG_RETRY set, while also having an error
flag set (e.g. AC_ERR_TIMEOUT), ata_eh_finish() will not increment
scmd->allowed, so the command will at most be retried scmd->allowed number
of times (which by default is set to 3).
However, scsi_eh_flush_done_q() will only retry commands for which
scsi_noretry_cmd() returns false.
For a command that has DID_TIME_OUT set, while also having either the
FAILFAST flag set, or the command being a passthrough command,
scsi_noretry_cmd() will return true. Thus, such a command will never be
retried.
Thus, make sure that libata sets SCSI's DID_TIME_OUT flag for commands that
actually timed out (libata's AC_ERR_TIMEOUT flag), such that timed out
commands will once again not be retried if they are also a FAILFAST or
passthrough command.

Old device trees for some platforms already define wifi nodes for the WCN
family of chips since before power sequencing was added upstream.
These nodes don't consume the regulator outputs from the PMU, and if we
allow this driver to bind to one of such "incomplete" nodes, we'll see a
kernel log error about the infinite probe deferral.
Extend the driver by adding a platform data struct matched against the
compatible. This struct contains the pwrseq target string as well as a
validation function called right after entering probe().
For Qualcomm WCN models, check the existence of the regulator supply
property that indicates the DT is already using power sequencing and return
-ENODEV if it's not there, indicating to the driver model that the device
should not be bound to the pwrctl driver.

In mtk_crtc_create(), if the call to mbox_request_channel() fails then we
set the "mtk_crtc->cmdq_client.chan" pointer to NULL. In that situation,
we do not call cmdq_pkt_create().
During the cleanup, we need to check if the "mtk_crtc->cmdq_client.chan"
is NULL first before calling cmdq_pkt_destroy(). Calling
cmdq_pkt_destroy() is unnecessary if we didn't call cmdq_pkt_create() and
it will result in a NULL pointer dereference.

It was reported that after resume from suspend a PCI error is logged
and connectivity is broken. Error message is:
PCI error (cmd = 0x0407, status_errs = 0x0000)
The message seems to be a red herring as none of the error bits is set,
and the PCI command register value also is normal. Exception handling
for a PCI error includes a chip reset what apparently brakes connectivity
here. The interrupt status bit triggering the PCI error handling isn't
actually used on PCIe chip versions, so it's not clear why this bit is
set by the chip. Fix this by ignoring this bit on PCIe chip versions.

[Why&How]
Disabling P-State support on full updates for DCN401 results in
introducing additional communication with SMU. A UCLK hard min message
to SMU takes 4 seconds to go through, which was due to DCN not allowing
pstate switch, which was caused by incorrect value for TTU watermark
before blanking the HUBP prior to DPG on for servicing the test request.
Fix the issue temporarily by disallowing pstate changes for compliance
test while test request handler is reworked for a proper fix.

[Why&How]
vblank immediate disable currently does not work for all asics. On
DCN401, the vblank interrupts never stop coming, and hence we never
get a chance to trigger idle optimizations.
Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

The issue here is that pm_runtime_disable_action() results in a call to
spi_geni_runtime_suspend(), which attempts to suspend the device and
disable an interconnect path that devm_icc_release() has just released.
Resolve this by calling geni_icc_get() before enabling runtime PM. This
approach ensures that when devres releases resources in reverse order,
it will start with pm_runtime_disable_action(), suspending the device,
and then proceed to free the remaining resources.

OVL_CON_CLRFMT_MAN is a configuration for extending color format
settings of DISP_REG_OVL_CON(n).
It will change some of the original color format settings.
Take the settings of (3 << 12) for example.
- If OVL_CON_CLRFMT_MAN = 0 means OVL_CON_CLRFMT_RGBA8888.
- If OVL_CON_CLRFMT_MAN = 1 means OVL_CON_CLRFMT_PARGB8888.
Since previous SoCs did not support OVL_CON_CLRFMT_MAN, this means
that the SoC does not support the premultiplied color format.
It will break the original color format setting of MT8173.
Therefore, the blend_modes is added to the driver data and then
mtk_ovl_fmt_convert() will check the blend_modes to see if
pre-multiplied is supported in the current platform.
If it is not supported, use coverage mode to set it to the supported
color formats to solve the degradation problem.

OVL_CON_AEN is for alpha blending enable.
For the SoC that is supported the blend_modes, OVL_CON_AEN will always
enabled to use constant alpha and then use the ignore_pixel_alpha bit
to do the alpha blending for XRGB8888 format.
Note that ignore pixel alpha bit is not supported if the SoC is not
supported the blend_modes.
So it will break the original setting of XRGB8888 format for the
blend_modes unsupported SoCs, such as MT8173.
To fix the downgrade issue, enable alpha blending only when a valid
blend_mode or has_alpha is set.

The fix for MAC addresses broke detection of the naming convention
because it gave network devices no random MAC before bind()
was called. This means that the check for the local assignment bit
was always negative as the address was zeroed from allocation,
instead of from overwriting the MAC with a unique hardware address.
The correct check for whether bind() has altered the MAC is

Until now, the conversion were triggered by setting high the GPIO
connected to the convst pin. This commit gives the possibility to
connect the convst pin to a PWM.
Connecting a PWM allows to have a better control on the samplerate,
but it must be handled with care, as it is completely decorrelated of
the driver's busy pin handling.
Hence it is not recommended to be used "as is" but must be exploited
in conjunction with IIO backend, and for now only a mock functionality
is enabled, i.e PWM never swings, but is used as a GPIO, i.e duty_cycle
== period equals high state, duty_cycle == 0 equals low state.
This mock functionality will be disabled after the IIO backend usecase
is introduced.

The BMP3xx and BMP5xx sensors have an interrupt pin which can be used as
a trigger for when there are data ready in the sensor for pick up.
This use case is used along with NORMAL_MODE in the sensor, which allows
the sensor to do consecutive measurements depending on the ODR rate value.
The trigger pin can be configured to be open-drain or push-pull and either
rising or falling edge.
No support is added yet for interrupts for FIFO, WATERMARK and out of range
values.

Add forced mode support in sensors BMP28x, BME28x, BMP3xx and BMP58x.
Sensors BMP18x and BMP085 are old and do not support this feature so
their operation is not affected at all.
Essentially, up to now, the rest of the sensors were used in normal mode
all the time. This means that they are continuously doing measurements
even though these measurements are not used. Even though the sensor does
provide PM support, to cover all the possible use cases, the sensor needs
to go into sleep mode and wake up whenever necessary.
The idea is that the sensor is by default in sleep mode, wakes up in
forced mode when a oneshot capture is requested, or in normal mode
when the buffer is enabled. The difference lays in the fact that in
forced mode, the sensor does only one conversion and goes back to sleep
while in normal mode, the sensor does continuous measurements with the
frequency that was set in the ODR registers.
The bmpX_chip_config() functions which are responsible for applying
the requested configuration to the sensor, are modified accordingly
in order to set the sensor by default in sleep mode.
DEEP STANDBY, Low Power NORMAL and CONTINUOUS modes, supported only by
the BMP58x version, are not added.
