27c035fff4 drivers: spi: use CPU clock frequency in configuration on CC13XX/CC26XX
The SPI peripheral should be configured using the CPU clock speed and
not the system clock speed. This used to be fine because they were the
same before #19232, but now that the system clock is RTC-based (which
has a different frequency), we can no longer make that assumption.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Same deal as in commit 677f1e6db9 ("config: Turn pointless/confusing

overlooked) stuff.

Also clean up formatting a bit, replacing spaces with tabs and
shortening the header.

975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

f43bae38e8 dts: Use separate compatibles for Nordic SPI/SPIM/SPIS peripherals
This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.

Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:

* dts/bindings/spi/
  new binding for "nordic,nrf-spim" is added and common fields for all
  3 types of Nordic SPI peripherals are extracted to a shared file

* dts/arm/nordic/
  "compatible" properties in spiX nodes are updated (when there is no
  choice as only one type of SPI peripheral is available) or replaced
  with a comment pointing out that the proper type of peripheral needs
  to be picked at some upper layer

* drivers/spi/
  spi_nrfx_spim driver is updated with the new form of macros generated
  from dts

* boards/
  all spiX nodes in dts files for boards equipped with an nRF chip are
  updated with the proper "compatible" property, according to the type
  of SPI peripheral that is currently selected for the board by the
  corresponding Kconfig choice option (SPI_x_NRF_SPI*)

075c94f6e2 kernel: Port remaining syscalls to new API
These calls are not accessible in CI test, nor do they get built on
common platforms (in at least one case I found a typo which proved the
code was truly unused).  These changes are blind, so live in a
separate commit.  But the nature of the port is mechanical, all other
syscalls in the system work fine, and any errors should be easily
corrected.

5f481bb042 drivers: rearrange for standard use of extern "C" in private headers
Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.

Only updated in headers that already had support for drivers built with
a C++ compiler.

The spi_dw.h file defines macros to declare functions, then uses them
within a file that may have out-of-tree overrides.  In this case we
leave the including file extern "C" active for backward compatibility.

Background from issue #17997:

Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.

Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

This commit solves an issue where the NSS must be set before the
mode on the stm32mp157c_dk2, else LL_SPI_SetMode won't affect the

stm32mp1x (and stm32h7) LL function SPI_Init seems to also define
first the NSS then the mode, unlike other STM32 boards where this
is not specified.
Changing the order shouldn't have bad repercussions on other boards,

This adds support for the async API for SAM0 SERCOM SPI using
DMA to drive the device.  This implementation does the reload
for both transmit and receive in the receive DMA handler.
Doing this simplifies the implementation but means that the
transmit drains completely, resulting in the SPI clock pausing
between buffers while both are reloaded in the receive handler.
