Ulf Magnusson 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*/# /'

Ulf Magnusson 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.

Kumar Gala 8a50048b2b kconfig: serial: sam0: Convert to use new kconfigfunctions
Convert use of dt_int_val to dt_compat_enabled.  As we want to
remove dt_int_val.

Kumar Gala 4e7863dc41 dts: Make instance defines consistent
We generated a define for each instance to convey its existance of the
form:
	#define DT_<COMPAT>_<INSTANCE> 1

However we renamed all other instance defines to be of the form
DT_INST_<INSTANCE>_<FOO>.  To make things consistent we now generate a
define of the form:

	#define DT_INST_<INSTANCE>_<COMPAT> 1

We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses
to use the new form.

Fixes: #17650

Benjamin Valentin 4d89ff1232 drivers/uart: introduce SERIAL_SUPPORT_ASYNC option
Not all serial drivers support ASYNC operation and if they do,
they might not support it on every SoC.

Add the SERIAL_SUPPORT_ASYNC option to indicate ASYNC operation
is availiable.

Derek Hageman 55bb37e35c drivers: serial: sam0: Implement DMA async API
This adds support for the async API for SAM0 SERCOM USARTs using
DMA to drive the device.

Tested on SAMD21 with a few trivial programs and with
tests/drivers/uart/uart_async_api.

Benjamin Valentin 4d9486fc22 soc: sam0: Enable generic peripheral selection
Make sure that when e.g. CONFIG_SERIAL is set, CONFIG_UART_SAM0 is
selected automatically when the sam0 SoC family is used.

Ulf Magnusson 86c46864ee drivers: ethernet: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'
