b713807eab Documentation/sphinx/kernel_feat.py: use class directly
Now that get_feat is in Python, we don't need to use subprocess
to fork an executable file: we can use the feature classes
directly.

caa642bf3b tools/docs/get_feat.py: convert get_feat.pl to Python
As we want to call Python code directly at the Sphinx extension,
convert get_feat.pl to Python.

The code was made to be (almost) bug-compatible with the Perl
version, with two exceptions:

1. Currently, Perl script outputs a wrong table if arch is set
   to a non-existing value;

2. the ReST table output when --feat is used without --arch
   has an invalid format, as the number of characters for the
   table delimiters are wrong.

Those two bugs were fixed while testing the conversion.

Additionally, another caveat was solved:
the output when --feat is used without arch and the feature
doesn't exist doesn't contain an empty table anymore.

da218406dd serial: 8250_platform: simplify IRQF_SHARED handling
IRQF_SHARED is the only flag handled in __serial8250_isa_init_ports()
and serial8250_probe_platform(). There is no need to precompute the
flags. Instead, initialize port->irqflags directly in the for loop.

Note the "if (bool)" is cheap and these are not hot paths anyway.

37d55c92e9 serial: drop SERIAL_8250_DEPRECATED_OPTIONS
In 3.7, 8250 was unintentionally renamed to 8250_core. This happened in
the commit 835d844d1a (8250_pnp: do pnp probe before legacy probe).
This made 8250.<xxxx> module options effectively defunct. Instead,
8250_core.<xxxx> worked.

In 3.9, the commit f2b8dfd9e4 (serial: 8250: Keep 8250.<xxxx> module
options functional after driver rename) made the original options work
again by introducing a hack.

Later in 3.9, the commit 9196d8acd7 (TTY: 8250, revert module name
change) changed the module name back to 8250 (from 8250_core). Since
then, the hack was there to support the transient 8250_core.<xxxx>
options. Those were present only in the 3.7..3.9 range.

These transient options were deprecated by 9326b047e4 (TTY: 8250,
deprecated 8250_core.* options) in v3.9 too.

Now, after those 12 years, it is time to get rid of this hack
completely.

f374a33e90 serial: serial_core: simplify uart_ioctl() returns
Neither uart_do_autoconfig(), nor uart_wait_modem_status() can return
-ENOIOCTLCMD. The ENOIOCTLCMD checks are there to check if 'cmd' matched
against TIOCSERCONFIG, and TIOCMIWAIT respectively. (With 0 or error in
'ret', it does not matter.)

Therefore, the code can simply return from the TIOCSERCONFIG and
TIOCMIWAIT spots immediately.

To be more explicit, use 'if' instead of switch-case for those single
values.

And return without jumping to the 'out' label -- it can be removed too.

a48f822908 samples: work around glibc redefining some of our defines wrong
Apparently as of version 2.42, glibc headers define AT_RENAME_NOREPLACE
and some of the other flags for renameat2() and friends in <stdio.h>.

Which would all be fine, except for inexplicable reasons glibc decided
to define them _differently_ from the kernel definitions, which then
makes some of our sample code that includes both kernel headers and user
space headers unhappy, because the compiler will (correctly) complain
about redefining things.

Now, mixing kernel headers and user space headers is always a somewhat
iffy proposition due to namespacing issues, but it's kind of inevitable
in our sample and selftest code.  And this is just glibc being stupid.

Those defines come from the kernel, glibc is exposing the kernel
interfaces, and glibc shouldn't make up some random new expressions for
these values.

It's not like glibc headers changed the actual result values, but they
arbitrarily just decided to use a different expression to describe those
values.  The kernel just does

    #define AT_RENAME_NOREPLACE  0x0001

while glibc does

    # define RENAME_NOREPLACE (1 << 0)
    # define AT_RENAME_NOREPLACE RENAME_NOREPLACE

instead.  Same value in the end, but very different macro definition.

For absolutely no reason.

This has since been fixed in the glibc development tree, so eventually
we'll end up with the canonical expressions and no clashes.  But in the
meantime the broken headers are in the glibc-2.42 release and have made
it out into distributions.

Do a minimal work-around to make the samples build cleanly by just
undefining the affected macros in between the user space header include
and the kernel header includes.

6c84a61ac0 drivers/tty/vt: use umin() instead of min_t(u16, ...) for row/col limits
The row/column bounds (for a screen window box) are changed from
'offset one' to 'offset zero' and bound to the screen size using:
	v->xs = min_t(u16, v->xs - 1, vc->vc_cols - 1);
This has the side effect of converting zero to the limit.

A check I'm adding to min_t() reports that (u16)(v->xs - 1) (etc)
discards signiticant bits (because v->xs is promoted to 'int' before
the addition).
If v->xs is zero (it comes from userspace) it converts -1 to 0xffff.
This is then bounded to 'vc->vc_cols - 1' which will be fine.

Replace with:
	v->xs = umin(v->xs - 1, vc->vc_cols - 1);
which again converts a -1 to unsigned - this time to 0xffffffff,
with the same overall effect.

Whether zero is meant to mean the 'maximum size' is unknown.
I can't find any documentation for the ioctl and it pre-dates git.

Detected by an extra check added to min_t().

platform: arm64: thinkpad-t14s-ec: sleep after EC access
The ACPI ECRD and ECWR functions have a 10ms sleep at the end. It turns
out, that this is sometimes needed to avoid I2C transmission failures,
especially for functions doing regmap_update_bits (and thus read + write
shortly after each other). This fixes problems like the following
appearing in the kernel log:

leds platform::micmute: Setting an LED's brightness failed (-6)
leds platform::kbd_backlight: Setting an LED's brightness failed (-6)

The ACPI QEVT function used to read the interrupt status register also
has a 10ms sleep at the end. Without that there are problems with
reading multiple events following directly after each other resulting
in the following error message being logged:

Merge series from Andreas Kemnade <andreas@kemnade.info>:

Add a driver for the FP9931/JD9930 regulator which provides the
comparatively high voltages needed for electronic paper displays.

Datasheet for the FP9931 is at
https://www.fitipower.com/dl/file/flXa6hIchVeu0W3K

Although it is in English, it seems to be only downloadable
from the Chinese part of that website.
For the JD9930 there can be a datasheet found at
https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/JD9930_2D00_0.7_2D00_JUN_2D00_2019.pdf

To simplify things, include the hwmon part directly which is only
one register read and there are not other functions besides
regulators in this chip.

ASoC: codecs: wcd934x: add explicit soundwire depenency
WCD934x provides register read/write interface to soundwire controller via
slimbus. Eventhough there was no direct compile time dependency for
this so far, however after adding common wcd functions this dependency
became explict.

We can either move the soundwire specific bits from wcd-common to wcd-sdw.c or
something on those lines or explicity add this dependency in Kconfig.
Moving this wcd-sdw can fix reported compile issue but it does not make
sense to select this codec without soundwire configs.
Given the fact that WCD934x is very much providing soundwire functionality
it is better to specify the soundwire dependency explicity in Kconfig
which should also fix the below compile time error with combination
of wcd934x a built-in and soundwire a module and also allow this codec
selection only when soundwire is available.

Error log:
wcd-common.c:undefiined reference to `sdw_write'
sound/soc/codecs/wcd-common.o: in function `wcd_bus_config':

252f83d547 arm64: tegra: Device tree changes for v6.19-rc1
This contains a bunch of additions and improvements for older devices.
 Tegra210 devices now have empty reserved-memory nodes to improve inter-
 operability with certain bootloaders. These chips now also support more
 multimedia engines. A new variant of the Jetson Nano is also added.
 
 Jetson TX2 sees some improvements. PCI endpoint mode is improved for
 Tegra234 so that reset interrupts are properly routed.
 
 A new RTC device is added starting with Orin.
 
 Rounding things off is a flurry of small fixes for DT validation and USB
 OTG mode.

96710819d0 hwmon: (vt1211) Convert macros to functions to avoid TOCTOU
The macros IN_FROM_REG, TEMP_FROM_REG, and RPM_FROM_REG evaluate their
arguments multiple times. These macros are used in lockless show functions
involving shared driver data, leading to Time-of-Check to Time-of-Use race
conditions.

For example, RPM_FROM_REG checks if a value is 0 or 255, and then uses it
in a division. If the value is modified by another thread to 0 after the
check but before the division, it causes a divide-by-zero error.

Convert these macros to static functions. This guarantees that arguments
are evaluated only once (pass-by-value), fixing the race conditions.
Adhere to the principle of minimal changes by only converting the specific
macros involved in these lockless contexts.

3350e81c62 MediaTek ARM64 Device Tree updates
This adds support for new boards and variants based on different
 already supported MediaTek SoCs, and improves support for current
 boards.
 
 In particular:
  - New machines:
     - MT7988 BananaPi R4 Pro eMMC and SD router board with support
       for both Key-M and Key-E M.2 slots through DTB Overlays
     - MT8370 Grinn GenioSBC-510 (GenioSOM-510 + GenioBoard Edge AI)
     - MT8390 Grinn GenioSBC-700 (GenioSOM-700 + GenioBoard Edge AI)
  - New variant: MT8395 MediaTek Genio 1200 EVK with UFS
 
 ...preparation for new SoCs (MT8196 Kompanio Ultra, a clone of the
    MT6991 Dimensity 9400, and MT6878 Dimensity 7300) with the
    addition of GCE/PIO definitions
 
 ...improvements for already supported SoCs and machines:
  - MT7622/7981b/7986a/7988a gain support for reading SoC UUID from
    eFuse, used to generate a persistent MAC address on boards that
    don't have any factory-assigned addresses.
  - MT7986 BananaPi R3 gets changes to its default fan PWM speed to
    improve compatibility with cheaper fans (usually coming with the
    heatsink+fan combos)
  - The MT7981b OpenWRT One router sees general support improvements
    with the enablement of its UART-0 console and correct pinmuxing
    for the same, addition of reserved memory for Trusted Firmware A,
    its SPI NOR Flash (for recovery system, WiFi eeprom data and ETH
    MAC address from factory), and board LEDs.
  - MT8365 gets support for its Mali G52 MC1 GPU, which gets enabled
    in the MediaTek Genio 350 EVK board
 
 ...and a dt-bindings warning fix for MT8183 machines through trivial
 changes to rename the audiosys and afe nodes to reflect bindings.

Samsung DTS ARM64 changes for v6.19

1. ExynosAutov920:
 - Add more clock controller nodes.

2. Google GS101:
 - PMIC clock
 - Mark ACPM (Alive Clock and Power Manager) firmware node as clock
   provider and use its clocks.  Add also Devicetree binding headers
   with clock its clock indices used in DTS (kept as separate branch).
 - Add more SYSREG (syscon) regions.
 - Correct several blocks address space sizes and APM SYSREG's starting
   address.

3. Exynos7870:
 - Enable display over DSI and several display planels.
 - Few cleanups.

platform/x86: ayaneo-ec: Add suspend hook
The Ayaneo EC resets after hibernation, losing the charge control state.
Add a small PM hook to restore this state on hibernation resume.

The fan speed is also lost during hibernation, but since hibernation
failures are common with this class of devices, setting a low fan speed
when the userspace program controlling the fan will potentially not
take over could cause the device to overheat, so it is not restored.

platform/x86: ayaneo-ec: Move Ayaneo devices from oxpec to ayaneo-ec
Currently, the oxpec driver contains Ayaneo devices. Move them to the
new ayaneo-ec driver, which is dedicated to them.

As this driver supports charge inhibition for Ayaneo, add support for it
for the AIR, AIR 1S, AB05-Medoncino, AIR Pro, and Kun, referenced from
the out-of-tree ayaneo-platform driver.

In addition, update the readmes of oxpec to reflect this change.

platform/x86: ayaneo-ec: Add controller power and modules attributes
The Ayaneo 3 features hot-swappable controller modules. The ejection
and management is done through HID. However, after ejecting the modules,
the controller needs to be power cycled via the EC to re-initialize.

For this, the EC provides a variable that holds whether the left or
right modules are connected, and a power control register to turn
the controller on or off. After ejecting the modules, the controller
should be turned off. Then, after both modules are reinserted,
the controller may be powered on again to re-initialize.

This patch introduces two new sysfs attributes:
 - `controller_modules`: a read-only attribute that indicates whether
   the left and right modules are connected (none, left, right, both).
 - `controller_power`: a read-write attribute that allows the user
   to turn the controller on or off (with '1'/'0').

Therefore, after ejection is complete, userspace can power off the
controller, then wait until both modules have been reinserted
(`controller_modules` will return 'both') to turn on the controller.

platform/x86: ayaneo-ec: Add charge control support
Ayaneo devices support charge inhibition via the EC. This inhibition
only works while the device is powered on, and resets between restarts.
However, it is maintained across suspend/resume cycles.

The EC does not support charge threshold control. Instead, userspace
software on Windows manually toggles charge inhibition depending on
battery level.
