USB4 DP BW Allocation uses DP_TUNNELING_IRQ to indicate the status update.
The DP_TUNNELING_IRQ is defined in LINK_SERVICE_IRQ_VECTOR_ESI0. When
receiving DP HPD IRQ in USB4, read the LINK_SERVICE_IRQ_VECTOR_ESI0.

[Why]
If we soft reset before halt finishes and there are outstanding
memory transactions then the memory interface may produce unexpected
results, such as out of order transactions when the firmware next runs.
These can manifest as random or unexpected load/store violations.
[How]
Increase the timeout before soft reset to ensure the DMCUB has quiesced.
This is effectively 1s maximum based on experimentation.
Use the enable bit check on DCN31 like we're doing on DCN35 and reorder
the reset writes to follow the HW programming guide.
Ensure we're reading SCRATCH7 instead of SCRATCH8 for the HALT code.
No current versions of DMCUB firmware use the SCRATCH8 boot bit to
dynamically switch where the HALT code goes to maintain backwards
compatibility with PSP.

There is a type mismatch between what CalculateDynamicMetadataParameters()
takes and what is passed to it. Currently this function accepts several
args as signed long but it's called with unsigned integers and integer. On
some systems where long is 32 bits and one of these unsigned int params is
greater than INT_MAX it may cause passing input params as negative values.
Fix this by changing these argument types from long to unsigned int and to
int respectively. Also this will align the function's definition with
similar functions in other dcn* drivers.

The utf16_le_to_7bit function claims to, naively, convert a UTF-16
string to a 7-bit ASCII string. By naively, we mean that it:
* drops the first byte of every character in the original UTF-16 string
* checks if all characters are printable, and otherwise replaces them
by exclamation mark "!".
This means that theoretically, all characters outside the 7-bit ASCII
range should be replaced by another character. Examples:
* lower-case alpha (ɒ) 0x0252 becomes 0x52 (R)
* ligature OE (œ) 0x0153 becomes 0x53 (S)
* hangul letter pieup (ㅂ) 0x3142 becomes 0x42 (B)
* upper-case gamma (Ɣ) 0x0194 becomes 0x94 (not printable) so gets
replaced by "!"
The result of this conversion for the GPT partition name is passed to
user-space as PARTNAME via udev, which is confusing and feels questionable.
However, there is a flaw in the conversion function itself. By dropping
one byte of each character and using isprint() to check if the remaining
byte corresponds to a printable character, we do not actually guarantee
that the resulting character is 7-bit ASCII.
This happens because we pass 8-bit characters to isprint(), which
in the kernel returns 1 for many values > 0x7f - as defined in ctype.c.
This results in many values which should be replaced by "!" to be kept
as-is, despite not being valid 7-bit ASCII. Examples:
* e with acute accent (é) 0x00E9 becomes 0xE9 - kept as-is because
isprint(0xE9) returns 1.
* euro sign (€) 0x20AC becomes 0xAC - kept as-is because isprint(0xAC)
returns 1.
This way has broken pyudev utility[1], fixes it by using a mask of 7 bits
instead of 8 bits before calling isprint.

The parameters set by the set_params call are only applied to the block
device in the start_dev call. So if a device has already been started, a
subsequently issued set_params on that device will not have the desired
effect, and should return an error. There is an existing check for this
- set_params fails on devices in the LIVE state. But this check is not
sufficient to cover the recovery case. In this case, the device will be
in the QUIESCED or FAIL_IO states, so set_params will succeed. But this
success is misleading, because the parameters will not be applied, since
the device has already been started (by a previous ublk server). The bit
UB_STATE_USED is set on completion of the start_dev; use it to detect
and fail set_params commands which arrive too late to be applied (after
start_dev).

Commit 434e5ca5b5 ("drm/panthor: Expose size of driver internal BO's over
fdinfo") locks the VMS xarray, to avoid UAF errors when the same VM is
being concurrently destroyed by another thread. However, that puts the
current thread in atomic context, which means taking the VMS' heap locks
will trigger a warning as the thread is no longer allowed to sleep.
Because in this case replacing the heap mutex with a spinlock isn't
feasible, the fdinfo handler no longer traverses the list of heaps for
every single VM associated with an open DRM file. Instead, when a new heap
chunk is allocated, its size is accumulated into a pool-wide tally, which
also makes the atomic context code path somewhat faster.

lured me to try populating it directly in the GPIO driver probe instead
of using the init_valid_mask() callback. It took some retries with
different bitmaps and eventually a bit of code-reading to understand why
the valid_mask was not obeyed. I could've avoided this trial and error if
the valid_mask was hidden in the struct gpio_device instead of being a
visible member of the struct gpio_chip.
Help the next developer who decides to directly populate the valid_mask
in struct gpio_chip by hiding the valid_mask in struct gpio_device and
keep it internal to the GPIO core.

The valid_mask member of the struct gpio_chip is unconditionally written
by the GPIO core at driver registration. It should not be directly
populated by the drivers. Hiding the valid_mask in struct gpio_device
makes it clear it is not meant to be directly populated by drivers. This
means drivers should not access it directly from the struct gpio_chip.
The gpio-rcar checks the valid mask in set/get_multiple() operations.
This is no longer needed [1]. Drop these checks.
Additionally, the valid_mask is needed for enabling the GPIO inputs at
probe time. Use the new valid_mask -getter function instead of accessing
it directly from the struct gpio_chip.

The valid_mask member of the struct gpio_chip is unconditionally written
by the GPIO core at driver registration. It shouldn't be directly
populated by drivers. This can be prevented by moving it from the struct
gpio_chip to struct gpio_device, which is internal to the GPIO core.
As a preparatory step, provide a getter function which can be used by
those drivers which need the valid_mask information.

When GPIOs were requested the validity of GPIOs were checked only when
the GPIO-chip had the request -callback populated. This made using
masked GPIOs possible.
The GPIO chip driver authors may find it difficult to understand the
relation of enforsing the GPIO validity and the 'request' -callback
because the current documentation for the 'request' callback does not
mention this. It only states:
* @request: optional hook for chip-specific activation, such as
* enabling module power and clock; may sleep
The validity of the GPIO line should be checked whether the driver
provides the 'request' callback or not.
Unconditionally check the GPIO validity when GPIO is being requested.

When I read through the TSO codes, I found out that we probably
miss initializing the tx_flags of last seg when TSO is turned
off, which means at the following points no more timestamp
(for this last one) will be generated. There are three flags
to be handled in this patch:
1. SKBTX_HW_TSTAMP
2. SKBTX_BPF
3. SKBTX_SCHED_TSTAMP
Note that SKBTX_BPF[1] was added in 6.14.0-rc2 by commit
6b98ec7e88 ("bpf: Add BPF_SOCK_OPS_TSTAMP_SCHED_CB callback")
and only belongs to net-next branch material for now. The common
issue of the above three flags can be fixed by this single patch.
This patch initializes the tx_flags to SKBTX_ANY_TSTAMP like what
the UDP GSO does to make the newly segmented last skb inherit the
tx_flags so that requested timestamp will be generated in each
certain layer, or else that last one has zero value of tx_flags
which leads to no timestamp at all.
