Kumar Gala b493f484df arch: arm: soc: Cleanup Kconfig inclusion per SoC
When we included SoC specific Kconfig files we do something like:

gsource "arch/arm/soc/arm/*/Kconfig.soc"

However, we should do that inside an if block for that SoC family so as
to limit SoC family specific options to only being visible when that SoC
family is selected.  So we simply move the gsource and related items
inside the if SOC_FAMILY_<SOC> block.

Fixes: #7452

Erwan Gouriou 081c9c3bec scripts: extract_dts_includes: Generate'_0' defines only when needed
Indexed defines were systematically generated even when there
was only one element to generate.
So we ended up generated a lot of _0 defines.
Then we needed to generate aliases to these _0 indexed defines,
in order to get useful defines.
For instance:
 #define GPIO_LEDS_0_GPIO_FLAGS_0	4
 #define GPIO_LEDS_0_GPIO_PIN_0		5
 #define GPIO_LEDS_0_GPIO_FLAGS		GPIO_LEDS_0_GPIO_FLAGS_0
 #define GPIO_LEDS_0_GPIO_PIN		GPIO_LEDS_0_GPIO_PIN_0

This commit allows to generate _0 indexed define only if a
property has more than one elements to define.
Aliases generation to _0 indexed defines are also removed.

Note: IRQ are left untouched since this is frequent to handle
multiple IRQs in a driver

Ulf Magnusson 547ed9b563 kconfig: Make 'source' non-globbing and use 'gsource'
Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:

  - The patch needs to be maintained separately

  - Misspelled filenames are silently ignored, as they look like glob
    patterns that don't match anything

Fix it as follows:

  1. Replace all 'source' statements that use wildcards with 'gsource'

  2. Remove the custom Kconfiglib patch so that 'source' no longer globs

The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.

source's that use environment variables that might contain glob patterns
were manually changed to gsource.

Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.

Kumar Gala ad18f84f50 arch: arm: Refactor CONFIG_CORTEX_M
Clean up Kconfig so each SoC just selects the specific Cortex-M
implementaiton rather than having to select both CORTEX_M and
CORTEX_{M0, M3, M4, etc.}.

Michael Hope a8a36a23fc spi: sam0: use Device Tree for configuration.
Switch the SoC device tree to define a single entry per SERCOM instead
of one per mode.

Define a Device Tree binding for the SAM0 SPI and use it instead of
Kconfig for enabling / disabaling instances

Switch the Arduino Zero, Adafruit Feather M0 Basic Proto, and
Trinket M0 to use the new defintion.

Add the APA102 LED that's on the Trinket as a test.

Michael Hope 247782a7b3 sam0: move the UART and SPI configuration into pinmux.
Also pull out the SERCOM pads configuration to defines.  Note that the
SAM0 has a two level configuration - a signal (like TX) is mapped to a
pad, and then a pad is mapped to a function on a pin.
