Commit ceddfd4493 ("media: i2c: imx219: Support four-lane operation")
added support for device tree to allow configuration of the sensor to
use 4 lanes with a link frequency of 363MHz, and amended the advertised
pixel rate to 280.8MPix/s.
However it didn't change any of the PLL settings, so actually it would
have been running overclocked in the MIPI block, and with the frame
rate and exposure calculations being wrong as the pixel rate was
unchanged.
The pixel rate and link frequency advertised were taken from the "Clock
Setting Example" section of the datasheet. However those are based on an
external clock of 12MHz, and are unachievable with a clock of 24MHz - it
seems PREPLLCLK_VT_DIV and PREPLLCK_OP_DIV can ONLY be set via the
automatic configuration documented in "9-1-2 EXCK_FREQ setting depend on
INCK frequency", not by writing the registers.
The closest we can get with a 24MHz clock is 281.6MPix/s and 364MHz.
Dropping all support for the 363MHz link frequency would cause problems
for existing users, so allow it, but log a warning that the requested
value is being changed to the supported one.

commit 7146dffa87 upstream.
The change to only use interrupts to handle supported status changes
introduced an issue when it is necessary to poll for the status. Rather
than checking for the status after sleeping the code now sleeps after
the check. This means a correct, but slower, status change on the part
of the TPM can be missed, resulting in a spurious timeout error,
especially on a more loaded system. Switch back to sleeping *then*
checking. An up front check of the status has been done at the start of
the function, so this does not cause an additional delay when the status
is already what we're looking for.

commit b8665a1b49 upstream.
In 2020, there's been an unnoticed change which rightfully attempted to
report probe deferrals upon DMA absence by checking the return value of
dma_request_chan_by_mask(). By doing so, it also reported errors which
were simply ignored otherwise, likely on purpose.
This change actually turned a void return into an error code. Hence, not
only the -EPROBE_DEFER error codes but all error codes got reported to
the callers, now failing to probe in the absence of Rx DMA channel,
despite the fact that DMA seems to not be supported natively by many
implementations.
Looking at the history, this change probably led to:
ad2775dc3f ("spi: cadence-quadspi: Disable the DAC for Intel LGM SoC")
f724c296f2 ("spi: cadence-quadspi: fix Direct Access Mode disable for SoCFPGA")
In my case, the AM62A LP SK core octo-SPI node from TI does not
advertise any DMA channel, hinting that there is likely no support for
it, but yet when the support for the am654 compatible was added, DMA
seemed to be used, so just discarding its use with the
CQSPI_DISABLE_DAC_MODE quirk for this compatible does not seem the
correct approach.
Let's get change the return condition back to:
- return a probe deferral error if we get one
- ignore the return value otherwise
The "error" log level was however likely too high for something that is
expected to fail, so let's lower it arbitrarily to the info level.

commit e403e85383 upstream.
The code for detecting CPUs that are vulnerable to Spectre BHB was
based on a hardcoded list of CPU IDs that were known to be affected.
Unfortunately, the list mostly only contained the IDs of standard ARM
cores. The IDs for many cores that are minor variants of the standard
ARM cores (like many Qualcomm Kyro CPUs) weren't listed. This led the
code to assume that those variants were not affected.
Flip the code on its head and instead assume that a core is vulnerable
if it doesn't have CSV2_3 but is unrecognized as being safe. This
involves creating a "Spectre BHB safe" list.
As of right now, the only CPU IDs added to the "Spectre BHB safe" list
are ARM Cortex A35, A53, A55, A510, and A520. This list was created by
looking for cores that weren't listed in ARM's list [1] as per review
feedback on v2 of this patch [2]. Additionally Brahma A53 is added as
per mailing list feedback [3].
NOTE: this patch will not actually _mitigate_ anyone, it will simply
cause them to report themselves as vulnerable. If any cores in the
system are reported as vulnerable but not mitigated then the whole
system will be reported as vulnerable though the system will attempt
to mitigate with the information it has about the known cores.

commit 9b98a7d2e5 upstream.
Variable allocated by charlcd_alloc() should be released
by charlcd_free(). The following patch changed kfree() to
charlcd_free() to fix an API misuse.

As the search for Device Control report is permissive, make sure the
desired field was actually found, before trying to set it.
Fix bitmask clearing as it was erronously using index instead of
index - 1 (HID arrays index is 1-based).
Add last two missing Device Control usages to the defined array.
PID_PAUSE and PID_CONTINUE.

As per USB PID standard:
INFINITE - Referrers to the maximum value of a range. i.e. if in an 8
bit unsigned field the value of 255 would indicate INFINITE.
Detecting 0xffff (U16_MAX) is still important as we MIGHT get this value
as infinite from some native software as 0 was never actually defined
in Linux' FF api as the infinite value. I'm working on it though.

Ensures the loop count will never exceed the logical_maximum.
Fixes implementation errors happening when applications use the max
value of int32/DWORD as the effect iterations. This could be observed
when running software both native and in wine.

If an error happens on the device, the driver will no longer fall
into the trap of reading this status 60 times before it decides that
this reply won't change to success/memory full.
Greatly reduces communication overhead during device error situation.

As noted by Anssi some 20 years ago, pool report is sometimes messed up.
This worked fine on many devices but casued oops on VRS DirectForce PRO.
Here, we're making sure pool report is refetched before trying to access
any of it's fields. While loop was replaced with a for loop + exit
conditions were moved aroud to decrease the possibility of creating an
infinite loop scenario.

[ Upstream commit 5d98079b2d ]
We only want to refetch the pool report during device init. Reset
function is now called when uploading effects to an empty device so
extract pool fetch to separate function and call it from init before
autocenter check (autocenter check triggered reset during init).
Remove a superfluous pointer declaration and assigment as well.
