Kumar Gala 5a8a06661d drivers: gpio: cleanup select HAS_DTS_GPIO
All GPIO controller drivers support DTS so we can select HAS_DTS_GPIO
at the GPIO driver subsystem level rather than for each specific driver.

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.

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 e65f8ba1f2 kconfig: gpio: Remove lots of redundant GPIO dependencies
Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

Maureen Helm 5dc584975b drivers: gpio: Select HAS_DTS_GPIO in various drivers
Selects HAS_DTS_GPIO in various gpio drivers that already support dts,
similar to how we select HAS_DTS_SPI in spi drivers and HAS_DTS_I2C in
i2c drivers.

Ulf Magnusson f912dfebea drivers: gpio: 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 ...'

Piggyback a missing 'source "drivers/gpio/Kconfig.imx"'. This file
wasn't included anywhere previously.
