Pull NVMe write streams removal from Jens Axboe:
"This removes the write streams support in NVMe. No vendor ever really
shipped working support for this, and they are not interested in
supporting it.
With the NVMe support gone, we have nothing in the tree that supports
this. Remove passing around of the hints.
The only discussion point in this patchset imho is the fact that the
file specific write hint setting/getting fcntl helpers will now return
-1/EINVAL like they did before we supported write hints. No known
applications use these functions, I only know of one prototype that I
help do for RocksDB, and that's not used. That said, with a change
like this, it's always a bit controversial. Alternatively, we could
just make them return 0 and pretend it worked. It's placement based
hints after all"
* tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block:
fs: remove fs.f_write_hint
fs: remove kiocb.ki_hint
block: remove the per-bio/request write hint
nvme: remove support or stream based temperature hint

With the NVMe support for this gone, there are no consumers of these hints
left, so remove them.

This support was added for RocksDB, but RocksDB ended up not using it.
At the same time drives on the open marked (vs those build for OEMs
for non-Linux support) that actually support streams are extremly
rare. Don't bloat the nvme driver for it.

Pull devicetree updates from Rob Herring:
- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
much needed help.
- DT schema validation now takes DTB files as input rather than
intermediate YAML files. This decouples the validation from the
source level syntax information. There's a bunch of schema fixes as a
result of switching to DTB based validation which exposed some errors
and incomplete schemas and examples.
- Kbuild improvements to explicitly warn users running 'make
dt_binding_check' on missing yamllint
- Expand DT_SCHEMA_FILES kbuild variable to take just a partial
filename or path instead of the full path to 1 file.
- Convert various bindings to schema format: mscc,vsc7514-switch,
multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
msm/mdp4, rda,8810pl-uart
- New schemas for u-boot environment variable partition, TI clksel
- New compatible strings for Renesas RZ/V2L SoC
- Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated
HiSilicon
- Add/fix schemas for QEMU Arm 'virt' machine
- Drop unused of_alias_get_alias_list() function
- Add a script to check DT unittest EXPECT message output. Pass
messages also now print by default at PR_INFO level to help test
automation.

drivers/tty/serial/xilinx_uartps.c, has since been refactored and no
longer needs this function. It also contained a Smatch checker warning:

Printing the devicetree unittest pass message for each passed test
creates much console verbosity. The existing pass messages are
printed at loglevel KERN_DEBUG so they will not print by default.
Change default to print the pass messages at loglevel PR_INFO so
they will print with the default console loglevel.
The test community expects either a pass or a fail message for each
test in a test suite. The messages are typically post-processed to
report pass/fail results.

The strlcpy should not be used because it doesn't limit the source
length. So that it will lead some potential bugs.
But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.
Thus, replace strlcpy with strscpy.

Clang warns on certain 32-bit architectures:
drivers/gpu/drm/selftests/test-drm_plane_helper.c:76:5: warning: stack frame size (1064) exceeds limit (1024) in 'igt_check_plane_state' [-Wframe-larger-than]
int igt_check_plane_state(void *ignored)
^
1 warning generated.
The structures in igt_check_plane_state() total 1008 bytes, so any small
amount of inlining will cause the stack frame to exceed the 32-bit limit
of 1024, triggering the warning.
Move these structures to static storage, which dramatically reduces the
amount of stack space in igt_check_plane_state(). There is no testing
impact, as igt_check_plane_state() is only called once in the driver.

The res is initialized here only if there's no errors so passing it to
ttm_resource_fini in the error paths results in a kernel oops. In the
error paths, instead of the unitialized res, we have to use to use
node->base on which ttm_resource_init was called.

Don't just mask off all the PSF GV points when SAGV gets disabled.
This should in fact cause the Pcode to reject the request since
at least one PSF point must remain enabled at all times.

For modern platforms the spec explicitly states that a
SAGV block time of zero means that SAGV is not supported.
Let's extend that to all platforms. Supposedly there should
be no systems where this isn't true, and it'll allow us to:
- use the same code regardless of older vs. newer platform
- wm latencies already treat 0 as disabled, so this fits well
with other related code
- make it a bit more clear when SAGV is used vs. not
- avoid overflows from adding U32_MAX with a u16 wm0 latency value
which could cause us to miscalculate the SAGV watermarks on tgl+

ICL+ PLLs can't genenerate certain frequencies. Running the PLL
algorithms through for all frequencies 25-594MHz we see a gap just
above 500 MHz. Specifically 500-522.8MHZ for TC PLLs, and 500-533.2
MHz for combo PHY PLLs. Reject those frequencies hdmi_port_clock_valid()
so that we properly filter out unsupported modes and/or color depths

Use devm_add_action_or_reset() instead of devm_add_action()+hand writing
what is done in the release function, should an error occur.
This is more straightforward and saves a few lines of code.
While at it, remove a useless test in devm_backlight_release(). 'data' is
known to be not NULL when this function is called.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.
The print function dev_err() is redundant because platform_get_irq()
already prints an error.

x86/ACPI boards with an arizona WM5102 codec ship with either Windows or
Android as factory installed OS.
The ACPI fwnode for the codec on Android boards misses 2 things compared
to the Windows boards (this is hardcoded in the Android board kernels):
1. There is no CLKE ACPI method to enabe the 32 KHz clock the codec needs
for jack-detection.
2. The GPIOs used by the codec are not listed in the fwnode for the codec.
The ACPI tables on x86/ACPI boards shipped with Android being incomplete
happens a lot. The special drivers/platform/x86/x86-android-tablets.c
module contains DMI based per model handling to compensate for this.
This module will enable the 32KHz clock through the pinctrl framework
to fix 1. and it will also register a gpio-lookup table for all GPIOs
needed by the codec + machine driver, including the GPIOs coming from
the codec itself.
Add an arizona_spi_acpi_android_probe() function which waits for the
x86-android-tablets to have set things up before continue with probing
the arizona WM5102 codec.

x86/ACPI boards with an arizona WM5102 codec ship with either Windows or
Android as factory installed OS.
The ACPI fwnode describing the codec differs depending on the factory OS,
and the current arizona_spi_acpi_probe() function is tailored for use
with the Windows board ACPI tables.
Split out the Windows board ACPI tables specific bits into a new
arizona_spi_acpi_windows_probe() function in preparation for also
adding support for the Android board ACPI tables.

This debugfs isn't used by anyone, if we want to dump the contents
of registers we should just convert the driver to regmap instead.
I'm also excluding this from the device tree bindings when converting
to YAML because it is not a real device, and device trees should
only contain real physical devices.

Returning a non-zero value in an i2c remove callback results in the i2c
core emitting a very generic error message ("remove failed (-ESOMETHING),
will be ignored") and as the message indicates not further error handling
is done.
Instead emit a more specific error message and then return zero in
.remove().
The long-term goal is to make the i2c remove prototype return void, making
all implementations return 0 is preparatory work for this change.

For the CRC PMIC we end up with multiple IRQ domains with the same fwnode.
One for the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various cells (known as the level 1 interrupts);
And 2 more for the irqchips which are part of the crystal_cove_gpio
and crystal_cove_charger cells.
This leads to the following error being printed when
CONFIG_GENERIC_IRQ_DEBUGFS is enabled:
debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present!
Set the bus token of the main IRQ domain to DOMAIN_BUS_NEXUS to avoid
this error, this also allows irq_find_matching_fwspec() to find the
right domain if necessary.
Note all 3 domain registering drivers need to set the IRQ domain bus token.
This is necessary because the IRQ domain code defaults to creating
the debugfs dir with just the fwnode name and then renames it when
the bus token is set. So each one starts with the same default name and
all 3 must be given a different name to avoid problems when one of the
other drivers loads and starts with the same default name.
