sources, since this is now discouraged.

e2b1762cf3 documentation/networking: update l2tp docs
l2tp no longer uses sk_user_data in tunnel sockets and now manages
tunnel/session lifetimes slightly differently. Update docs to cover
this.

2c04a4defc arm64: dts: rockchip: drop dr_mode for Radxa ZERO 3W/3E
since dr_mode = "otg" can be used for USB gadget functions for U-Boot
and Linux, there is no reason to set it to "peripheral". drop it.

8c51521de1 arm64: dts: rockchip: Raise Pinebook Pro's panel backlight PWM frequency
Increase the frequency of the PWM signal that drives the LED backlight of
the Pinebook Pro's panel, from about 1.35 KHz (which equals to the PWM
period of 740,740 ns), to exactly 8 kHz (which equals to the PWM period of
125,000 ns).  Using a higher PWM frequency for the panel backlight, which
reduces the flicker, can only be beneficial to the end users' eyes.

On top of that, increasing the backlight PWM signal frequency reportedly
eliminates the buzzing emitted from the Pinebook Pro's built-in speakers
when certain backlight levels are set, which cause some weird interference
with some of the components of the Pinebook Pro's audio chain.

The old value for the backlight PWM period, i.e. 740,740 ns, is pretty much
an arbitrary value that was selected during the very early bring-up of the
Pinebook Pro, only because that value seemed to minimize horizontal line
distortion on the display, which resulted from the old X.org drivers causing
screen tearing when dragging windows around.  That's no longer an issue, so
there are no reasons to stick with the old PWM period value.

The lower and the upper backlight PWM frequency limits for the Pinebook Pro's
panel, according to its datasheet, are 200 Hz and 10 kHz, respectively. [1]
These changes still leave some headroom, which may have some positive effects
on the lifetime expectancy of the panel's backlight LEDs.

aad4183232 gpio: mlxbf3: Support shutdown() function
During Linux graceful reboot, the GPIO interrupts are not disabled.
Since the drivers are not removed during graceful reboot,
the logic to call mlxbf3_gpio_irq_disable() is not triggered.
Interrupts that remain enabled can cause issues on subsequent boots.

For example, the mlxbf-gige driver contains PHY logic to bring up the link.
If the gpio-mlxbf3 driver loads first, the mlxbf-gige driver
will use a GPIO interrupt to bring up the link.
Otherwise, it will use polling.
The next time Linux boots and loads the drivers in this order, we encounter the issue:
- mlxbf-gige loads first and uses polling while the GPIO10
  interrupt is still enabled from the previous boot. So if
  the interrupt triggers, there is nothing to clear it.
- gpio-mlxbf3 loads.
- i2c-mlxbf loads. The interrupt doesn't trigger for I2C
  because it is shared with the GPIO interrupt line which
  was not cleared.

The solution is to add a shutdown function to the GPIO driver to clear and disable
all interrupts. Also clear the interrupt after disabling it in mlxbf3_gpio_irq_disable().

8e0eb3dea9 arm64: dts: rockchip: add rfkill node for M.2 E wifi on orangepi-5-plus
This follows the same logic as 82d40b141a ("arm64: dts: rockchip: add
rfkill node for M.2 Key E WiFi on rock-5b").

On the orangepi-5-plus, there's also a GPIO pin connecting the WiFi
enable signal inside the M.2 Key E slot.

The exact GPIO PIN can be validated in the Armbian rk-5.10-rkr4 kernel
rk3588-orangepi-5-plus.dtsi file [1], which contains a `wifi_disable`
node referencing RK_PC4 on &gpio0.

With this change, I was able to get a "Intel Corporation Wi-Fi
6E(802.11ax) AX210/AX1675* 2x2 [Typhoon Peak] (rev 1a)" up, while
`rfkill` previously only mentioned to be hardware blocked.

02a62b551c tools/nolibc: compiler: introduce __nolibc_has_attribute()
Recent compilers support __has_attribute() to check if a certain
compiler attribute is supported.
Unfortunately we have to first check if __has_attribute is supported in
the first place and then if a specific attribute is present.
These two checks can't be folded into a single condition as that would
lead to errors.

Nesting the two conditions like below works, but becomes ugly as soon
as #else blocks are used as those need to be duplicated for both levels
of #if.

    #if defined __has_attribute
    #  if __has_attribute (nonnull)
    #    define ATTR_NONNULL __attribute__ ((nonnull))
    #  endif
    #endif

Introduce a new helper which makes the usage of __has_attribute() nicer
and migrate the current user to it.

6fc839dc32 iio: adc: stm32-dfsdm: add scaling support to dfsdm
Add scaling support to STM32 DFSDM.

When used in an analog context, a DFSDM filter typically converts the data
from a sigma delta modulator. The IIO device associated to the DFSDM
filter provides these data as raw data.
The IIO device can provide scaling information (voltage and offset) to
allow conversion of raw data into physical values.

With the new binding based on IIO backend framework, the sigma delta
modulators are defined as backends providing scaling information.

The scaling is not supported with legacy binding.

bd71b6d0ba iio: add iio backend support to sd modulator
The legacy sd modulator driver registers the sigma delta modulator as
an IIO channel provider. This implementation is not convenient when the
SD modulator has to be cascaded with another IIO device. The scaling
information is distributed across devices, which makes it difficult to
report consistent scaling data on IIO devices.

The solution is to expose these cascaded IIO devices as an aggregate
device, which report global scaling information.

Legacy binding:
DFSDM is an IIO channel consumer.
SD modulator is an IIO channels provider.
The channel phandles are provided in DT through io-channels property
and channel indexes through st,adc-channels property.

New binding:
DFSDM is an IIO channel provider.
The channel indexes are given by reg property in channel child node.

This new binding is intended to be used with SD modulator IIO backends.
It does not support SD modulator legacy IIO devices.
The st,adc-channels property presence is used to discriminate

Change the DFSDM binding to use the new IIO backend framework,
along with the adoption of IIO generic channels.
This binding change allows to add scaling support to the DFSDM.

Keep the legacy binding as deprecated for backward compatibility.

The io-backends property is supported only in generic IIO channel
binding.

- Channel description with the generic binding (Audio and Analog):

  Properties superseded by generic properties:
    st,adc-channels: becomes "reg" property in channel node
    st,adc-channel-names: becomes "label" property in channel node
  Properties moved to channel child node:
    st,adc-channel-types: becomes st,adc-channel-type
    st,adc-channel-clk-src, st,adc-alt-channel

- Analog binding:

  DFSDM filter channel is configured as an IIO backend consumer.
  Add io-backends property in channel child nodes.

  DFSDM is no more configured as a channel consumer from SD modulator.
  Use of io-channels in DFSDM node is deprecated.

- Audio binding:

  DFSDM audio DAI is configured as a channel consumer from DFSDM filter.
  No change compare to legacy.

03f9885c60 irqchip/riscv-aplic: Retrigger MSI interrupt on source configuration
The section 4.5.2 of the RISC-V AIA specification says that "any write
to a sourcecfg register of an APLIC might (or might not) cause the
corresponding interrupt-pending bit to be set to one if the rectified
input value is high (= 1) under the new source mode."

When the interrupt type is changed in the sourcecfg register, the APLIC
device might not set the corresponding pending bit, so the interrupt might
never become pending.

To handle sourcecfg register changes for level-triggered interrupts in MSI
mode, manually set the pending bit for retriggering interrupt so it gets
retriggered if it was already asserted.
