Currently Soundcard has 1 rx device for headset and SoundWire Speaker Playback.
This setup has issues, ex if we try to play on headset the audio stream is
also sent to SoundWire Speakers and we will hear sound in both headsets and speakers.
Make a separate device for Speakers and Headset so that the streams are
different and handled properly.

The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in
the kernel the Regulators and Clocks are controlled by an OpRegion
driver designed to work with power control methods defined in ACPI, but
some platforms lack those methods, meaning drivers need to be able to
consume the resources of these chips through the usual frameworks.
This commit adds a driver for the regulators provided by the tps68470,
and is designed to bind to the platform_device registered by the
intel_skl_int3472 module.
This is based on this out of tree driver written by Intel:
https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/regulator/tps68470-regulator.c
with various cleanups added.

Commit fab8a02b73 ("serial: 8250_fintek: Enable high speed mode on Fintek F81866")
introduced support to use high baudrate with Fintek SuperIO UARTs. It'll
change clocksources when the UART probed.
But when user add kernel parameter "console=ttyS0,115200 console=tty0" to make
the UART as console output, the console will output garbled text after the
following kernel message.
[ 3.681188] Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled
The issue is occurs in following step:
probe_setup_port() -> fintek_8250_goto_highspeed()
It change clocksource from 115200 to 921600 with wrong time, it should change
clocksource in set_termios() not in probed. The following 3 patches are
implemented change clocksource in fintek_8250_set_termios().

Linus suspected that "struct tty_ldisc"->ops->write_wakeup() must not
sleep, and Jiri confirmed it from include/linux/tty_ldisc.h. Thus, defer
n_hdlc_send_frames() from n_hdlc_tty_wakeup() to a WQ context like

The MDIO bus speed must be initialized before talking to the PHY the first
time in order to avoid talking to it using a speed that the PHY doesn't
support.
This fixes HW initialization error -17 (IXGBE_ERR_PHY_ADDR_INVALID) on
Denverton CPUs (a.k.a. the Atom C3000 family) on ports with a 10Gb network
plugged in. On those devices, HLREG0[MDCSPD] resets to 1, which combined
with the 10Gb network results in a 24MHz MDIO speed, which is apparently
too fast for the connected PHY. PHY register reads over MDIO bus return
garbage, leading to initialization failure.
Reproduced with Linux kernel 4.19 and 5.15-rc7. Can be reproduced using
the following setup:
* Use an Atom C3000 family system with at least one X552 LAN on the SoC
* Disable PXE or other BIOS network initialization if possible
(the interface must not be initialized before Linux boots)
* Connect a live 10Gb Ethernet cable to an X550 port
* Power cycle (not reset, doesn't always work) the system and boot Linux
* Observe: ixgbe interfaces w/ 10GbE cables plugged in fail with error -17

In `igbvf_probe`, if register_netdev() fails, the program will go to
label err_hw_init, and then to label err_ioremap. In free_netdev() which
is just below label err_ioremap, there is `list_for_each_entry_safe` and
`netif_napi_del` which aims to delete all entries in `dev->napi_list`.
The program has added an entry `adapter->rx_ring->napi` which is added by
`netif_napi_add` in igbvf_alloc_queues(). However, adapter->rx_ring has
been freed below label err_hw_init. So this a UAF.
In terms of how to patch the problem, we can refer to igbvf_remove() and
delete the entry before `adapter->rx_ring`.

If I created a kunitconfig file that was incomplete, then
$ ./tools/testing/kunit/kunit.py build --kunitconfig=my_kunitconfig
would silently drop all the options with unmet dependencies!
This is because it doesn't do the config check that `kunit.py config`
does.
So if I want to safely build a kernel for testing, I have to do
$ ./tools/testing/kunit/kunit.py config <flags>
$ ./tools/testing/kunit/kunit.py build <flags, again>
It seems unlikely that any user of kunit.py would want the current
`build` semantics.
So make it effectively do `kunit.py config` + `kunit.py build`.

The `log` field is unused, and the `status` field is accessible via
`test.status`.
So it's simpler to just return the main `Test` object directly.
And since we're no longer returning a namedtuple, which has no type
annotations, this hopefully means typecheckers are better equipped to
find any errors.

namedtuple is a terse way of defining a collection of fields.
However, it does not allow us to annotate the type of these fields.
It also doesn't let us have any sort of inheritance between types.
Since commit df4b0807ca ("kunit: tool: Assert the version
requirement"), kunit.py has asserted that it's running on python >=3.7.
So in that case use a 3.7 feature, dataclasses, to replace these.
Changes in detail:
* Make KunitExecRequest contain all the fields needed for exec_tests
* Use inheritance to dedupe fields
* also allows us to e.g. pass a KUnitRequest in as a KUnitParseRequest
* this has changed around the order of some fields
* Use named arguments when constructing all request objects in kunit.py
* This is to prevent accidentally mixing up fields, etc.

If the audit daemon were ever to get stuck in a stopped state the
kernel's kauditd_thread() could get blocked attempting to send audit
records to the userspace audit daemon. With the kernel thread
blocked it is possible that the audit queue could grow unbounded as
certain audit record generating events must be exempt from the queue
limits else the system enter a deadlock state.
This patch resolves this problem by lowering the kernel thread's
socket sending timeout from MAX_SCHEDULE_TIMEOUT to HZ/10 and tweaks
the kauditd_send_queue() function to better manage the various audit
queues when connection problems occur between the kernel and the
audit daemon. With this patch, the backlog may temporarily grow
beyond the defined limits when the audit daemon is stopped and the
system is under heavy audit pressure, but kauditd_thread() will
continue to make progress and drain the queues as it would for other
connection problems. For example, with the audit daemon put into a
stopped state and the system configured to audit every syscall it
was still possible to shutdown the system without a kernel panic,
deadlock, etc.; granted, the system was slow to shutdown but that is
to be expected given the extreme pressure of recording every syscall.
The timeout value of HZ/10 was chosen primarily through
experimentation and this developer's "gut feeling". There is likely
no one perfect value, but as this scenario is limited in scope (root
privileges would be needed to send SIGSTOP to the audit daemon), it
is likely not worth exposing this as a tunable at present. This can
always be done at a later date if it proves necessary.

Due to the audit control mutex necessary for serializing audit
userspace messages we haven't been able to block/penalize userspace
processes that attempt to send audit records while the system is
under audit pressure. The result is that privileged userspace
applications have a priority boost with respect to audit as they are
not bound by the same audit queue throttling as the other tasks on
the system.
This patch attempts to restore some balance to the system when under
audit pressure by blocking these privileged userspace tasks after
they have finished their audit processing, and dropped the audit
control mutex, but before they return to userspace.

The Clock-and-Reset controller resides in a core power domain on NVIDIA
Tegra SoCs. In order to support voltage scaling of the core power domain,
we hook up DVFS-capable clocks to the core GENPD for managing of the
GENPD's performance state based on the clock changes.
Some clocks don't have any specific physical hardware unit that backs
them, like root PLLs and system clock and they have theirs own voltage
requirements. This patch adds new clk-device driver that backs the clocks
and provides runtime PM functionality for them. A virtual clk-device is
created for each such DVFS-capable clock at the clock's registration time
by the new tegra_clk_register() helper. Driver changes clock's device
GENPD performance state based on clk-rate notifications.
In result we have this sequence of events:
1. Clock driver creates virtual device for selective clocks, enables
runtime PM for the created device and registers the clock.
2. Clk-device driver starts to listen to clock rate changes.
3. Something changes clk rate or enables/disables clk.
4. CCF core propagates the change through the clk tree.
5. Clk-device driver gets clock rate-change notification or GENPD core
handles prepare/unprepare of the clock.
6. Clk-device driver changes GENPD performance state on clock rate
change.
7. GENPD driver changes voltage regulator state change.
8. The regulator state is committed to hardware via I2C.
We rely on fact that DVFS is not needed for Tegra I2C and that Tegra I2C
driver already keeps clock always-prepared. Hence I2C subsystem stays
independent from the clk power management and there are no deadlock spots
in the sequence.
Currently all clocks are registered very early during kernel boot when the
device driver core isn't available yet. The clk-device can't be created
at that time. This patch splits the registration of the clocks in two
phases:
1. Register all essential clocks which don't use RPM and are needed
during early boot.
2. Register at a later boot time the rest of clocks.
This patch adds power management support for Tegra20 and Tegra30 clocks.

A delay was already applied in dwc2_resume() when reactivating the

This patch adds delay after enabling STM ID/VBUS detection. Then, ID state
is good when initializing gadget and host, and avoid to get a wrong
