Unfortunately, at the time of writing this commit message, we have been
unable to get permission from Silead, or from device OEMs, to distribute
the necessary Silead firmware files in linux-firmware.
On a whole bunch of devices the UEFI BIOS code contains a touchscreen
driver, which contains an embedded copy of the firmware. The fw-loader
code has a "platform" fallback mechanism, which together with info on the
firmware from drivers/platform/x86/touchscreen_dmi.c will use the firmware
from the UEFI driver when the firmware is missing from /lib/firmware. This
makes the touchscreen work OOTB without users needing to manually download
the firmware.
The firmware bundled with the original Windows/Android is usually newer
then the firmware in the UEFI driver and it is better calibrated. This
better calibration can lead to significant differences in the reported
min/max coordinates.
Add support for a new (optional) "silead,efi-fw-min-max" property which
provides a set of alternative min/max values to use for the x/y axis when
the EFI embedded firmware is used.
The new property is only used on (x86) devices which do not use devicetree,
IOW it is not used in actual devicetree files. The devicetree-bindings
maintainers have requested properties like these to not be added to the
devicetree-bindings, so the new property is deliberately not added to the
existing silead devicetree-bindings documentation.

Some Goodix touchscreens have support for a (Goodix) active pen, add
support for this. The info on how to detect when a pen is down and to
detect when the stylus buttons are pressed was lifted from the out
of tree Goodix driver with pen support written by Adya:
https://gitlab.com/AdyaAdya/goodix-touchscreen-linux-driver/
Since there is no way to tell if pen support is present, the registering
of the pen input_dev is delayed till the first pen event is detected.
This has been tested on a Trekstor Surftab duo W1, a Chuwi Hi13 and
a Cyberbook T116 tablet.

When converting a rumble into a periodic effect, for compatibility,
the magnitude is effectively calculated using:
magnitude = max(strong_rubble / 3 + weak_rubble / 6, 0x7fff);
The rumble magnitudes are both u16 and the resulting magnitude is
s16. The max is presumably an attempt to limit the result of the
calculation to the maximum possible magnitude for the s16 result,
and thus should be a min.
However in the case of strong = weak = 0xffff, the result of the first
part of the calculation is 0x7fff, meaning that the min would be
redundant anyway, so simply remove the current max.

Modern devices may redraw display at 60 Hz, make sure we have one input
sample per one frame. Reduce sample period to 15ms, so we would get up
to 66.6 samples per second, although realistically with all the jitter
and extra scheduling wiggle room, we would end up just above 60 samples
per second. This should be a good compromise between sampling too often
and sampling too seldom.

Currently the ili210x driver implements a threaded interrupt handler which
starts upon edge on the interrupt line, and then polls the touch controller
for samples. Every time a sample is obtained from the controller, the thread
function checks whether further polling is required, and if so, waits fixed
amount of time before polling for next sample.
The delay between consecutive samples can thus vary greatly, because the
I2C transfer required to retrieve the sample from the controller takes
different amount of time on different platforms. Furthermore, different
models of the touch controllers supported by this driver require different
delays during retrieval of samples too.
Instead of waiting fixed amount of time before polling for next sample,
determine how much time passed since the beginning of sampling cycle and
then wait only the remaining amount of time within the sampling cycle.
This makes the driver deliver samples with equal spacing between them.

The ili251x touch controller needs 5ms delay between sending I2C device
address and register address, and, writing or reading register data.
According to downstream ili251x example code, this 5ms delay is not
required when reading touch samples out of the controller. Implement
such a special case.

The created rmi device is orphan, which breaks the real device
hierarchy, and can cause some trouble, especially during suspend
and resume sequences. E.g. in case of I2C, rmi dev should be child
of the I2C client device.
Fix this, assigning the transport device as parent of the rmi device.

The Host Performance Buffer feature allows UFS read commands to carry the
physical media addresses along with the LBAs, thus allowing less internal
L2P-table switches in the device. HPB1.0 allowed a single LBA, while
HPB2.0 increases this capacity up to 255 blocks.
Carrying more than a single record, the read operation is no longer purely
of type "read" but a "hybrid" command: Writing the physical address to the
device in one operation and reading back the required payload in another.
The JEDEC HPB spec defines two commands for this operation:
HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and
HPB-READ to read the payload.
With the current HPB design the UFS driver has no alternative but to divide
the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ.
This causes a great deal of aggravation to the block layer guys who
demanded that we completely revert the entire HPB driver regardless of the
huge amount of corporate effort already invested in it.
As a compromise, remove only the pieces that implement the 2.0
specification. This is done as a matter of urgency for the final 5.15
release.

Testing revealed a problem with how the reference tag was handled for
a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when
the controller is asked to generate the protection information
(i.e. not DIX). And as a result the initial reference tag would not be
set in the WRITE_INSERT case.
Separate handling of the REF_CHECK and REF_INCREMENT flags to align
with both the DIX spec and the MPI implementation.

According to discussion with Andrew as follow:
https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/
HNS3 driver needs to separate pause autoneg from general autoneg, so revert
this incorrect patch.

Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.
Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12
characters to print the list of LFs of each block for a PF/VF. If the
length of list of LFs of a block exceeds this fixed width then the list
gets truncated and displays only a part of the list. This patch fixes
this by using the maximum possible length of list of LFs among all
blocks of all PFs and VFs entries as the width size.

The driver allocates skb during ndo_open with GFP_ATOMIC which has high chance of failure when there are multiple instances.
GFP_KERNEL is enough while open and use GFP_ATOMIC only from interrupt context.

MTU change is refused whenever the value of new MTU is bigger than
the max packet bytes that fits in NFP Cluster Target Memory (CTM).
However, an eBPF program doesn't always need to access the whole
packet data.
The maximum direct packet access (DPA) offset has always been
caculated by verifier and stored in the max_pkt_offset field of prog
aux data.

[Why]
A deadlock in the kernel occurs when we fallback from the V3 to V2
add_topology_to_display or remove_topology_to_display because they
both try to acquire the dtm_mutex but recursive locking isn't
supported on mutex_lock().
[How]
Make the mutex_lock/unlock more fine grained and move them up such that
they're only required for the psp invocation itself.

[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.
[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).
