On VF hot remove, NETDEV_GOING_DOWN is sent to notify the VF is about to
go down. At this time, the VF is still sending/receiving traffic and we
request the VSP to switch datapath.
On completion, the datapath is switched to synthetic and we can proceed
with VF hot remove.

The driver currently does manual register manipulation in
multiple places to talk to a specific UART port.
In order to talk to a specific UART port over SPI, the bits U1
and U0 of the register address can be set, as explained in the
Command byte configuration section of the datasheet.
Make this more elegant by creating regmaps for each UART port
and setting the read_flag_mask and write_flag_mask
accordingly.
All communcations regarding global registers are done on UART
port 0, so replace the global regmap entirely with the port 0
regmap.
Also, remove the 0x1f masks from reg_writeable(), reg_volatile()
and reg_precious() methods, since setting the U1 and U0 bits of
the register address happens inside the regmap core now.

xHCI 4.9 explicitly forbids assuming that the xHC has released its
ownership of a multi-TRB TD when it reports an error on one of the
early TRBs. Yet the driver makes such assumption and releases the TD,
allowing the remaining TRBs to be freed or overwritten by new TDs.
The xHC should also report completion of the final TRB due to its IOC
flag being set by us, regardless of prior errors. This event cannot
be recognized if the TD has already been freed earlier, resulting in
"Transfer event TRB DMA ptr not part of current TD" error message.
Fix this by reusing the logic for processing isoc Transaction Errors.
This also handles hosts which fail to report the final completion.

The last TRB of a isoc TD might not trigger an event if there was
an error event for a TRB mid TD. This is seen on a NEC Corporation
uPD720200 USB 3.0 Host
After an error mid a multi-TRB TD the xHC should according to xhci 4.9.1
generate events for passed TRBs with IOC flag set if it proceeds to the
next TD. This event is either a copy of the original error, or a
"success" transfer event.
If that event is missing then the driver and xHC host get out of sync as
the driver is still expecting a transfer event for that first TD, while
xHC host is already sending events for the next TD in the list.
This leads to
"Transfer event TRB DMA ptr not part of current TD" messages.
As a solution we tag the isoc TDs that get error events mid TD.
If an event doesn't match the first TD, then check if the tag is
set, and event points to the next TD.
In that case give back the fist TD and process the next TD normally
Make sure TD status and transferred length stay valid in both cases
with and without final TD completion event.

working only because this driver do not activate autosuspend by default,
so it was visible only by warning "Runtime PM usage count underflow!".

If the interface is given an IP address while the device is
suspended (as a result of an auto-suspend event) there is a race
between lan78xx_resume() and lan78xx_open() that can result in an
exception or failure to handle incoming packets. The following
changes fix this problem.
Introduce a mutex to serialise operations in the network interface
open and stop entry points with respect to the USB driver suspend
and resume entry points.
Move Tx and Rx data path start/stop to lan78xx_start() and
lan78xx_stop() respectively and flush the packet FIFOs before
starting the Tx and Rx data paths. This prevents the MAC and FIFOs
getting out of step and delivery of malformed packets to the network
stack.
Stop processing of received packets before disconnecting the
PHY from the MAC to prevent a kernel exception caused by handling
packets after the PHY device has been removed.
Refactor device auto-suspend code to make it consistent with the
the system suspend code and make the suspend handler easier to read.
Add new code to stop wake-on-lan packets or PHY events resuming the
host or device from suspend if the device has not been opened
(typically after an IP address is assigned).

The MAC can get out of step with the internal packet FIFOs if the
system goes to sleep when the link is active, especially at high
data rates. This can result in partial frames in the packet FIFOs
that in result in malformed frames being delivered to the host.
This occurs because the driver does not enable/disable the internal
packet FIFOs in step with the corresponding MAC data path. The
following changes fix this problem.
Update code that enables/disables the MAC receiver and transmitter
to the more general Rx and Tx data path, where the data path in each
direction consists of both the MAC function (Tx or Rx) and the
corresponding packet FIFO.
In the receive path the packet FIFO must be enabled before the MAC
receiver but disabled after the MAC receiver.
In the transmit path the opposite is true: the packet FIFO must be
enabled after the MAC transmitter but disabled before the MAC
transmitter.
The packet FIFOs can be flushed safely once the corresponding data
path is stopped.

commit 2a93c6cbd5a703d44c414a3c3945a87ce11430ba upstream.
Commit 'e3e56c050ab6 ("soc: qcom: rpmhpd: Make power_on actually enable
the domain")' aimed to make sure that a power-domain that is being
enabled without any particular performance-state requested will at least
turn the rail on, to avoid filling DeviceTree with otherwise unnecessary
required-opps properties.
But in the event that aggregation happens on a disabled power-domain, with
an enabled peer without performance-state, both the local and peer
corner are 0. The peer's enabled_corner is not considered, with the
result that the underlying (shared) resource is disabled.
One case where this can be observed is when the display stack keeps mmcx
enabled (but without a particular performance-state vote) in order to
access registers and sync_state happens in the rpmhpd driver. As mmcx_ao
is flushed the state of the peer (mmcx) is not considered and mmcx_ao
ends up turning off "mmcx.lvl" underneath mmcx. This has been observed
several times, but has been painted over in DeviceTree by adding an
explicit vote for the lowest non-disabled performance-state.

Each time SD/mmc phy is initialized, at times, in some of
the attempts, phy fails to completes its initialization
which results into timeout error. Per the HW spec, it is
a pre-requisite to ensure a stable SD clock before a phy

AC5X spec says PHY init complete bit must be polled until zero.
We see cases in which timeout can take longer than the standard
calculation on AC5X, which is expected following the spec comment above.
According to the spec, we must wait as long as it takes for that bit to
toggle on AC5X.
Cap that with 100 delay loops so we won't get stuck forever.

commit ff3206d2186d84e4f77e1378ba1d225633f17b9b upstream.
Initializing an eMMC that's connected via a 1-bit bus is current failing,
if the HW (DT) informs that 4-bit bus is supported. In fact this is a
regression, as we were earlier capable of falling back to 1-bit mode, when
switching to 4/8-bit bus failed. Therefore, let's restore the behaviour.

The MII code does not check the return value of mdio_read (among
others), and therefore no error code should be sent. A previous fix to
the use of an uninitialized variable propagates negative error codes,
that might lead to wrong operations by the MII library.
An example of such issues is the use of mii_nway_restart by the dm9601
driver. The mii_nway_restart function does not check the value returned
by mdio_read, which in this case might be a negative number which could
contain the exact bit the function checks (BMCR_ANENABLE = 0x1000).
Return zero in case of error, as it is common practice in users of
mdio_read to avoid wrong uses of the return value.

present or not flashed, LAN7850 will fail to sync the speed detected by the PHY
with the MAC. In case link speed is 100Mbit, it will accidentally work,
otherwise no data can be transferred.
Better way would be to implement link_up callback, or set auto speed
configuration unconditionally. But this changes would be more intrusive.
So, for now, set it only if no EEPROM is found.

The relevant changes to the already existing GD5F1GQ4UExxG support has
been determined by consulting the GigaDevice product change notice
AN-0392-10, version 1.0 from November 30, 2020.
As the overlaps are huge, variable names have been generalized
accordingly.
Apart from the lowered ECC strength (4 instead of 8 bits per 512 bytes),
the new device ID, and the extra quad IO dummy byte, no changes had to
be taken into account.
New hardware features are not supported, namely:
- Power on reset
- Unique ID
- Double transfer rate (DTR)
- Parameter page
- Random data quad IO
The inverted semantic of the "driver strength" register bits, defaulting
to 100% instead of 50% for the Q5 devices, got ignored as the driver has
never touched them anyway.
The no longer supported "read from cache during block erase"
functionality is not reflected as the current SPI NAND core does not
support it anyway.
Implementation has been tested on MediaTek MT7688 based GARDENA smart
Gateways using both, GigaDevice GD5F1GQ5UEYIG and GD5F1GQ4UBYIG.

On some devices the ACPI name of the touchscreen is e.g. either
MSSL1680:00 or MSSL1680:01 depending on the BIOS version.
This happens for example on the "Chuwi Hi8 Air" tablet where the initial
commit's ts_data uses "MSSL1680:00" but the tablets from the github issue
and linux-hardware.org probe linked below both use "MSSL1680:01".
Replace the strcmp() match on ts_data->acpi_name with a strstarts()
check to allow using a partial match on just the ACPI HID of "MSSL1680"
and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly
to fix the touchscreen not working on models where it is "MSSL1680:01".
Note this drops the length check for I2C_NAME_SIZE. This never was
necessary since the ACPI names used are never more then 11 chars and
I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long
before reaching I2C_NAME_SIZE.

commit d28e4dff085c5a87025c9a0a85fb798bd8e9ca17 upstream.
As it turns out, my earlier patch in commit 86d46fdaa12a (block:
ataflop: fix breakage introduced at blk-mq refactoring) was
incomplete. This patch fixes any remaining issues found during
more testing and code review.
Requests exceeding 4 k are handled in 4k segments but
__blk_mq_end_request() is never called on these (still
sectors outstanding on the request). With redo_fd_request()
removed, there is no provision to kick off processing of the
next segment, causing requests exceeding 4k to hang. (By
setting /sys/block/fd0/queue/max_sectors_k <= 4 as workaround,
this behaviour can be avoided).
Instead of reintroducing redo_fd_request(), requeue the remainder
of the request by calling blk_mq_requeue_request() on incomplete
requests (i.e. when blk_update_request() still returns true), and
rely on the block layer to queue the residual as new request.
Both error handling and formatting needs to release the
ST-DMA lock, so call finish_fdc() on these (this was previously
handled by redo_fd_request()). finish_fdc() may be called
legitimately without the ST-DMA lock held - make sure we only
release the lock if we actually held it. In a similar way,
early exit due to errors in ataflop_queue_rq() must release
the lock.
After minor errors, fd_error sets up to recalibrate the drive
but never re-runs the current operation (another task handled by
redo_fd_request() before). Call do_fd_action() to get the next
steps (seek, retry read/write) underway.

[ Upstream commit 3c43177ffb54ea5be97505eb8e2690e99ac96bc9 ]
When waiting for a syncobj timeline point whose fence has not yet been
submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using
drm_syncobj_fence_add_wait and the thread is put to sleep until the
timeout expires. If the fence is submitted before then,
drm_syncobj_add_point will wake up the sleeping thread immediately which
will proceed to wait for the fence to be signaled.
However, if the WAIT_AVAILABLE flag is used instead,
drm_syncobj_fence_add_wait won't get called, meaning the waiting thread
will always sleep for the full timeout duration, even if the fence gets
submitted earlier. If it turns out that the fence *has* been submitted
by the time it eventually wakes up, it will still indicate to userspace
that the wait completed successfully (it won't return -ETIME), but it
will have taken much longer than it should have.
To fix this, we must call drm_syncobj_fence_add_wait if *either* the
WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only
difference being that with WAIT_FOR_SUBMIT we will also wait for the
fence to be signaled after it has been submitted while with
WAIT_AVAILABLE we will return immediately.

[ Upstream commit 0affdba22aca5573f9d989bcb1d71d32a6a03efe ]
clang-16 warns about casting between incompatible function types:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c:161:10: error: cast from 'void (*)(const struct firmware *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
161 | .fini = (void(*)(void *))release_firmware,
This one was done to use the generic shadow_fw_release() function as a
callback for struct nvbios_source. Change it to use the same prototype
as the other five instances, with a trivial helper function that actually
calls release_firmware.

[ Upstream commit 9ddf190a7df77b77817f955fdb9c2ae9d1c9c9a3 ]
JAZZ_ESP is a bool kconfig symbol that selects SCSI_SPI_ATTRS. When
CONFIG_SCSI=m, this results in SCSI_SPI_ATTRS=m while JAZZ_ESP=y, which
causes many undefined symbol linker errors.
Fix this by only offering to build this driver when CONFIG_SCSI=y.
[mkp: JAZZ_ESP is unique in that it does not support being compiled as a
module unlike the remaining SPI SCSI HBA drivers]
