In Synopsys's dwc3 data book:
To avoid underrun and overrun during the burst, in a high-latency bus
system (like USB), threshold and burst size control is provided through
GTXTHRCFG and GRXTHRCFG registers.
By default, USB TX and RX threshold are not enabled. To enable
TX or RX threshold, both packet threshold count and max burst size
properties must be set to a valid non-zero value.
In Realtek DHC SoC, DWC3 USB 3.0 uses AHB system bus. When dwc3 is
connected with USB 2.5G Ethernet, there will be overrun problem.
Therefore, setting TX/RX thresholds can avoid this issue.

Add the compatible string for SC8280 Multiport USB controller from
Qualcomm.
There are 4 power event irq interrupts supported by this controller
(one for each port of multiport). Added all the 4 as non-optional
interrupts for SC8280XP-MP
Also each port of multiport has one DP and oen DM IRQ. Add all DP/DM
IRQ's related to 4 ports of SC8280XP Teritiary controller.
Also added ss phy irq for both SS Ports.

Pull ARM SoC fixes from Arnd Bergmann:
"These are the latest bug fixes that have come up in the soc tree. Most
of these are fairly minor. Most notably, the majority of changes this

- Updates to the addresses of the broadcom and aspeed entries in the
MAINTAINERS file.
- Defconfig updates to address a regression on samsung and a build
warning from an unknown Kconfig symbol
- Build fixes for the StrongARM and Uniphier platforms
- Code fixes for SCMI and FF-A firmware drivers, both of which had a
simple bug that resulted in invalid data, and a lesser fix for the
optee firmware driver
- Multiple fixes for the recently added loongson/loongarch "guts" soc
driver
- Devicetree fixes for RISC-V on the startfive platform, addressing
issues with NOR flash, usb and uart.

Pull ATA fixes from Damien Le Moal:
"A larger than usual set of fixes for 6.6-rc4 due to the unexpected
number of fixes needed to address ATA disks suspend/resume issues.
In more detail:
- Add missing additionalProperties on child nodes to the pata-common
DT bindings (Rob)
- Fix handling of the REPORT SUPPORTED OPERATION CODES command to
ignore reserved bits (Niklas)
- Increase port multiplier soft reset timeout to accomodate slow
devices and avoid issues on wakeup (Matthias)
- A couple of minor code fixes to avoid compilation warnings in
libata-core and libata-eh (me)
- Many patches from me to address suspend/resume issues, and in
particular a potential deadlock on resume due to the SCSI disk
driver resume operation not being synchronized with libata EH port
resume handling.
This is addressed by changing the scsi disk driver disk start/stop
control to allow libata to execute disk suspend (spin down) and
resume (spin up) on its own during system suspend/resume. Runtime
suspend/resume control remains with the SCSI disk driver.
Other fixes include:
- Fix libata power management request issuing to avoid races
- Establish a link between ATA ports and SCSI devices to order PM
operations
- Fix device removal to avoid issues with driver rmmod removal
- Fix synchronization of libata device rescan and SCSI disk resume
operation
- Remove libsas PM operations as suspend/resume is handled
directly by the sas controller resume
- Fix the SCSI disk driver to not issue commands to suspended
disks, thus avoiding potential system lock-up on resume"

To complement panel-simple.yaml, create panel-simple-lvds-dual-ports.yaml.
panel-simple-lvds-dual-ports.yaml is for all simple LVDS panels that
have dual LVDS ports and require only a single power-supply.
The first port receives odd pixels, and the second port receives even pixels.
Optionally, a backlight and an enable GPIO can be specified as properties.
Panels with swapped pixel order, if any, need dedicated bindings.
Migrate 'auo,g133han01', 'auo,g185han01', 'auo,g190ean01',
'koe,tx26d202vm0bwa' and 'nlt,nl192108ac18-02d' over to the new file.
The objectives with one file for all the simple LVDS panels with dual ports are:
- Make it simpler to add bindings for this kind of LVDS panels
- Keep the number of bindings file lower
- Keep the binding documentation for this kind of LVDS panels more consistent
- Make it possible for drivers to get pixel order via
drm_of_lvds_get_dual_link_pixel_order(), as the 'ports' property is required

The Monolithic Power (MPS) MP3309C is a WLED step-up converter, featuring a
programmable switching frequency to optimize efficiency.
The brightness can be controlled either by I2C commands (called "analog"
mode) or by a PWM input signal (PWM mode).
This driver supports both modes.
For device driver details, please refer to:

Merge series from wangweidong.a@awinic.com:
The awinic aw87390 is a new high efficiency, low noise,
constant large volume, 6th Smart K audio amplifier.
Add two properties, the "awinic,audio-channel" property and the
"awinic,sync-flag". The "awinic,audio-channel" is used to make
different PA load different configurations, the "awinic,sync-flag"
is used to synchronize the phases of multiple PA. These two properties
will be read by the corresponding driver, allowing multi-PA to
achieve better playback effect.

On some Qualcomm platforms the firwmare, or hardware, does not
gracefully handle memory protection of the rmtfs memory region when
placed adjacent to other protected region. Some DeviceTree authors have
worked around this issue by explicitly reserving the space around the
region, but this prevents such author to use rely on the OS to place the
region, through the use of "size" (instead of a fixed location).
Introduce a flag to indicate that guard pages need be carved at the
beginning and end of the memory region. The user shall account for the
two pages in the defined size.
